DHP 507 (CAS: 36265-41-5), chemically known as Didodecyl 1,4-dihydro-2,6-dimethylpyridine-3,5-dicarboxylate, is a premium-grade stabilizer specifically engineered for the protection of PVC polymers. By leveraging a unique nitrogen-containing ring structure and long carbon chains, DHP 507 offers exceptional dispersion and stability, making it an essential additive for high-performance polymer systems.
Designed to enhance the stabilizing properties of calcium organic systems and mixed metal stabilizers, DHP 507 operates at low dosage levels (0.05% to 0.2%) without compromising the clarity of transparent applications. From rigid building materials and soft PVC composites to high-precision medical devices and automotive interiors, it provides critical protection against thermal degradation and weather-induced aging.
