Plastic Injection moulding is when the desired plastic raw material – PVC – is melted at desired temperature and state of viscosity where it can be injected from either 1 or multiple points into the mould. The mould for injection moulding is essentially filled by the material i.e. PVC compound. Items such as Gumboots, shoe soles, bath plug and floor tiles are all examples of plastic injection moulded products.
How is PVC made?
When it comes to PVC, it is important to know what exact process or part of the PVC chain you are referring to. There is the creation of PVC in terms of Polymer, PVC Resin in powder form and there is PVC Compound in granule form.
In essence, PVC is a thermoplastic with incredibly low crystallinity.
PVC Polymer
The creation of PVC begins with chlorine and ethylene which combines to create Ethylene Dichloride which then goes through a process called thermal cracking to create Vinyl Chloride Monomers (VCM). The VCM then goes through the process of resin conversion, also known as, polymerization which then creates what we know as Poly-Vinyl-Chloride (PVC).
PVC Resin
When PVC is in a powder form it is commonly known as PVC resin. PVC resin is commonly used in making of thermoplastics such as PVC compounds, which is the granules and pellets that you would see in manufacturing processes of PVC compounds or PVC products.
PVC Compound
Rigid PVC compound is essentially the combination of PVC powders, stabilizers, fillers, and additives which take the final form of solid and hard small granules/pellets. Flexible PVC compound is the combination of PVC polymer, plasticisers, stabilizers, and fillers additive which take the final form of softer granules/pellets or powder form with a combination of all the above additives
The manufacturing process of injection moulding is when the desired material – for example, PVC compounds/granules – is melted to a state of viscosity where it can be injected from either 1 or multiple points into the mould.
The manufacturing process of extrusion is when the desired plastic material is gradually melted in an extruder at desired and calculated temperatures and pressed through a die to form into profiles and tubes of any required length – for example, an aluminium window gaskets, wire or cable sheathing and pipes.
PVC Compounds come in various forms for a variety of applications and industries.
It is of vital importance to understand the key differences between the types of PVC Compound – or as some may know it PVC Granules/Pellets – before making your purchase. An important item to discuss with your supplier is the processing that the PVC will go through, e.g. extrusion or injection moulding to ensure the grade of the product suits processing type.
To get an easy understanding of the different types of PVC and what they can go into manufacturing, we can split it into three basic categories.
Flexible
A softer PVC compound carefully formulated and created to suit the manufacturing of “flexible” items such as footwear, gumboots, gaskets, irrigation products, tubes, hoses and cables.
Semi-Rigid PVC Compound
A PVC compound that is firm yet still has an element of flexibility which prevents the product from cracking or snapping. Applications that would require a semi-rigid PVC compound material could be items such as wire coating, gabions, fittings and floor tiles.
Rigid PVC Compound
A Rigid PVC compound would be for the purpose of manufacturing a hard and stiff product that has little to no room for flexibility. Items such as pipe fittings and pipes, appliance components, wall mounts or outlet boxes, bottles and containers, window frames and edge banding and many more!
PVC is highly durable because it is a non-abrasive, light material and stable. Additionally, It has non-corrosive properties, making it suitable for long-term use. It has a resistance to water and can be moulded or formed into different shapes or sizes.
PVC is an extremely safe material to use, with many practical applications as opposed to other types of plastic. This material is manufactured according to industry regulations and standards and must meet certain quality levels to be allowed for public use. For example, vinyl compounds can be used in footwear, healthcare, food, and beverage packaging.
Due to the high durability, longevity, and safety of PVC, it is quite versatile. The flexibility and make-up of PVC allow it to be made to specific requirements. So essentially, it can be as tough as you want it to be, and its thickness and weight are dependent on its use.
PVC is a highly recyclable plastic, and it can be processed several times and can have two to three new use functionalities. The recycling process does not affect its base, making it an essential material for sustainable and eco-conscious businesses.
PVC is also affordable because of how low-cost the material is. There is a minimal skill required for installation, and because of its durability, it makes for a fuss-free maintenance material.
It is important to understand the product that needs to be manufactured and the characteristics it should have. PVC is a good and safe plastic to use for a variety of items but depending on the product, it is also possible that PVC may not be the right choice. Here at IPC (Innovative Pvc Compounds) we have a team of experts that have years of experience in plastics, and specifically in PVC material who can advise if PVC is the right material for your requirements.
PVC is a diverse material which can be utilised for a variety of practices and procedures in the medical and healthcare industry. Polyvinyl Chloride (also known as PVC) as a type of plastic is used in the medical industry because it is cost effective for manufacturing of disposable items while still maintaining high quality for intimate human use. PVC is also easy to clean and sterilise and replace if required, making it a hygiene necessity in such environments. Both PVC raw materials and end products for the medical industry must follow strict manufacturing guidelines and protocols to ensure the utmost safety for the end user of the product. All additives must be of medical quality grade.
PVC comes in a variety of forms to suit various sectors and applications.
The most common forms are PVC pellets/granules, PVC dry blend/powder and emulsion/liquid PVC. These types of PVC are used in different sectors for different applications that are most suited for a particular form of PVC to manufacture a certain product.
IPC (Innovative Pvc Compounds) specialize in virgin grade PVC compounds in pellet/granule form and service a variety of industries and sectors that manufacture further products from our PVC compound material.
The mould in the blow moulding process would be a cavity which would be filled by the material of the product i.e. the pvc compound. In the blow moulding process, the air blows the material internally – like a balloon – which covers the inner side of the mould to create the shape of the desired product. Injection moulding, however, is when the material is melted to a state of viscosity where it can be injected from either 1 or multiple points into the mould. The mould for injection moulding is essentially filled by the material i.e. pvc compound.

When it comes to the manufacturing industry, many businesses around the world use PVC to make products for the footwear, gaskets, cling film, automotive and even medical fields and more. PVC has many uses for everyday purposes, and the material can be found in many different everyday products we may not realize such as footwear (gumboots and shoe soles), profile gaskets for aluminium doors and windows, interlocking floor tiles (such as those in factories and retail display stores, garages, and workshops!), hose pipes and tubes, electrical, construction, and automotive parts and components. PVC is also used in medical items such as catheter bags, blood bags and tubing. The uses for PVC are so vast that it is almost impossible to list them all!
Black PVC is a compound that contains the pigment carbon black. White PVC is a compound containing a white pigment titanium dioxide.
Plastics has become a vital part of our lives and surrounds us in more ways than before. Plastic types such as PVC are used in the automotive industry because it is more practical, economical, durable and can be made UV resistant if required. Take a moment to think of your car and how many parts of it are made of plastics, now imagine that all those little pieces were made of much more expensive materials – it has a ripple effect and makes the automotive too expensive for the general consumers to purchase. Plastics can also be made to be lightweight but still maintain durability and strength which is important to the automotive industry.
PVC stands for PolyVinyl Chloride and it is a type of strong and durable raw material that is used to create many plastic products. It is versatility ranges from being hard and brittle to soft and malleable. PVC is one of the most widely used plastics globally because of its versatility, durability, and affordability. PVC material is used in a wide range of industries including Footwear, Automotive, Electrical, Plumbing, Medical/Healthcare and Food industries.
PVC is the abbreviation for Poly Vinyl Chloride. PVC a synthetic thermoplastic polymer and comes in different forms such as Rigid or Flexible PVC. These are plastic compounds containing hydrogen, carbon, and chlorine. These types of compounds – or granules – have many applications, and we specialise in the plastics used for footwear, safety shoes, gumboots, wire coating, floor tiles, electrical and plumbing fittings, for the moulding and extrusion industries.
Here at IPC, we specialize in the manufacturing and supply of flexible, semi-rigid and rigid PVC granules to various industries.
There is a fundamental difference between PVC and HDPE which is the basic chemical composition that creates these two polymers. PVC is short for Polyvinyl Chloride and HDPE is an abbreviation for High-Density Polyethylene. These two types of plastic are vastly different in a lot of ways including their strength, weight, durability, and flexibility.
White PVC includes an additive called titanium dioxide which essentially strips the compound/granule of any hue that should still be there from the natural form of the PVC. Grey PVC is created by adding pigment additives to the compound which creates an enhance the colour required.
The key differences in PVC pipes and Polyethylene pipes is the different types of plastic that each have their own advantages and disadvantages. Essentially the key differences between these two materials is that PVC pipes/fittings are usually more cost effective and usually used in pressurized and suspended water systems. PE pipes and fittings are generally more costly as they are created to withstand regular extreme temperatures and fluctuations as well as high pressure.
Plasticized PVC refers to the fact that the material when manufactured into a product will be flexible in some way or form. The plasticizer is an agent that allows for the PVC to be softer and thus more flexible and can vary across products accordingly. The less plasticizer used, the more Semi-Rigid and Rigid the product becomes.

Strength and durability can be engineered to be as strong as you require within the characteristics of plastic.
One can identify a PVC plastic by checking the density, however this can vary across grades of PVC that was used in the manufacturing of the product.
One can also use the burn-test. The material burns but extinguishes itself on removal of the flame. The flame colour will be yellow with a green base and the odour will be acrid (unpleasant/pungent). The fumes will also be acidic, and you may smell a faint chlorine odour.
