PVC Stabilisers are added either directly into PVC or in combination to prevent oxidation, chain scission, uncontrolled recombination, and cross-linking reactions caused by photo oxidation. Essentially, they protect PVC from the harmful effects of extreme temperature and ultraviolet radiations. PVC Stabilisers are of different types like Heat Stabilisers which are mainly used in Construction projects. Antioxidants are PVC Stabilisers that prevent oxidation of PVC from taking place due to atmospheric oxygen. Hindered amine light stabilizers are PVC Stabilizers that scavenge radicals produced by weathering. The next type of PVC Stabilisers are UV absorbers. They dissipate energy absorbed by UV rays. Antiozonants are PVC Stabilisers that prevent degradation of materials cause by Ozone gas present in the atmosphere. Lastly, PVC Stabilisers are available in the form of Organosulfur Compounds that thermally stabilize polymers.
PVC Stabilisers are mainly used in the manufacture of Pipes and Fittings, Window Profiles, Rigid and semi-rigid films, wires and cables, coatings, and flooring etc. PVC Stabilisers are available in the form of Heat and UV Stabilisers, Flame Retardants, Smoke Suppressants, Plasticizers, Processing Aids, Impact Modifiers, Thermal Modifiers, Pigments, and Fillers that are added to PVC for strengthening purposes. The applications of a PVC Stabiliser are in all places where PVC is used. PVC is widely used in construction material, medical devices, children’s toys, protective housing for cables and wires, manufacture of credit cards etc. PVC is also used in rubber seals, vinyl fabrics, and automotive parts. Impact Modifier/Processing Aid PVC Stabilisers provide softness and flexibility that PVC does not normally have.
