Plastic additives Industry Information
The versatility of plastic materials comes from the ability to mold, laminate or shape them, and to tailor them physically and chemically. There is a plastic suitable for almost every application and we find plastics everywhere in our daily life. Thermoplastic resins such as PVC, polyethylene (PE), polystyrene (PS), polypropylene (PP) or acrylonitrile-butadiene-styrene-copolymer (ABS) are exposed to different sources of degradation: from thermal degradation during processing to photoinitiated decomposition. Consequently, the lifetime and durability of these plastics would be significantly reduced. Evanstab® products are powerful secondary antioxidants to prevent photooxidative degradation of polymers but can also be utilized in the manufacturing of tin-sulfur stabilizers required for thermoplastic processing of polyvinylchloride (PVC).
Plastics Secondary Antioxidants
Protection against photoinitiated degradation is mandatory for lifetime extension of polymers. Evanstab® secondary antioxidants offer superior performance in the protection of polymers against photooxidative or thermal degradation.
Plastics PVC-Heat Stabilizer
Heat stabilizers are required during extrusion processing of PVC to prevent thermal degradation of PVC. Evanstab® products are mandatory for the manufacturing of highly efficient tin-sulfur heat stabilizers.
