It has a low volatility at high temperatures and high resistance to thermal degradation and can therefore be used without significant loss or decomposition in the polyolefin compounding and molding processes. It is especially suited for polyolefins and cold cured polyesters. It protects polymers from UV radiation helping to preserve the original appearance and physical integrity, especially for polyolefins and polyester resins. Packing 25kg/fiber drum; 25kg/carton, or as per customer’s request. Storage Containers should be kept tightly closed when not in use. Store it in a dry, cool, well-ventilated shady place.
