AI Overview
N-phenylmaleimide (N-PMI, CAS 941-69-5) is a high-efficiency heat-resistant modifier for PVC resin, typically used in 10-30wt% concentration to improve Vicat softening temperature by 10-25°C. It improves heat resistance, hardness, impact resistance, and processability in PVC, ABS, and PMMA, often acting as a comonomer or additive to increase thermal stability.

Is PVC resin a plastic?
It is a thermoplastic resin derived from salt (57%) and oil or gas (43%). It is the world's third-most widely produced synthetic plastic polymer, after polyethylene and polypropylene. PVC resin is often supplied in powder form. It is resistant to oxidation and degradation, which allows for a long storage period.
