Antimony Trioxide Substitutes

Antimony trioxide alternative flame retardant fully considers the characteristics of PVC leather, PVC profiles, cable materials, and PVC/NBR foam rubber. It is scientifically compounded with multiple inorganic flame retardant components without affecting physical properties, enabling complementary performance to reduce the amount of flame retardant used, and achieve the goals of improving material flame retardancy, processing performance, and physical mechanical properties.
I. Product Performance:

II. Application Instructions:
Recommended dosage: 3 - 10% Wt flame retardant + 3 - 5% Wt antimony trioxide.
