UltraCarb
Introduction
UltraCarb is a powdered inorganic flame retardant composed of two main components: hydromagnesite and magnesium carbonate hydroxide. It features a unique three‑stage flame‑retardant mechanism:
Release of crystalline water
Release of carbon dioxide
Formation of a hard carbonized layer on the surface, which blocks the fire source and rapidly interrupts combustion reactions.
Applications
UltraCarb can be widely used in PE, PP, EVA, PVC, NBR, EPDM, CR, CPE, silicone rubber, and various synthetic resins.
Typical addition level: 10–60%, depending on customer requirements.
