Why Does PVC Need Additives

To begin with, let’s make it clear that PVC only requires additives when manufacturing products out of the material. Additives are used to give desirable qualities to the final product according to the manufacturer. Some additives protect the PVC from excessive heat which is a natural by-product of the processing itself. This keeps things in control so that the final product be it PVC Pipes, Cables, Profiles, or anything else keeps itself strong and stable in shape and structure. So what is the most important PVC additive that’s used in just about every product while manufacturing? The answer is: Stabilisers.

Stabilisers

As the name itself suggests these additives stabilise the PVC while processing. Earlier, Lead based stabilisers were the norm because of their qualities as well as price. However, later on it was discovered that lead based stabilisers are harmful to human health as well as incredibly toxic to the environment. This made researchers look for a different way of producing this additive and the answer was CaZn stabilisers. Our own company has researched for years looking for the perfect stabilisers for great results.

CaZn stabilisers are just as good as Lead ones in terms of insulating qualities. They also have great mechanical and electrical capacities and the right CaZn stabiliser can provide just the right initial colouring to your PVC product. Moreover, they’re environment friendly and completely harmless to human health.
