PE Special Flame Retardant Masterbatch

Flame retardant masterbatch is an additive used for polyethylene (PE) materials. It can effectively improve the flame retardant performance of plastic products and is widely applied in processes such as film blowing, injection molding, extrusion and wire drawing. Its main components are environmentally friendly bromine-based, antimony-based or phosphorus-based flame retardants. It features low addition dosage, good dispersibility, no precipitation, and no impact on the transparency and mechanical properties of materials. The product complies with environmental standards such as RoHS and REACH, with a flame retardant rating reaching UL94 V-0.

3. Product Application: 

Suitable for polyolefin materials such as LDPE, HDPE, LLDPE and EVA. 

It is especially applicable to scenarios with high fire protection requirements, including construction safety nets, cable sheaths, automotive wiring harness tubes, flame-retardant tarpaulins, foam insulation pipes and other similar products. 

4. Notes on Use: 

1) Packaging and Storage: Adopt paper-plastic composite packaging bags, 25KG per bag. Store in a dry and cool place. Keep the package sealed when not in use to prevent contamination, direct sunlight and moisture. 

2) Transportation Requirements: Avoid severe collision and keep away from fire sources. 

3) Processing Suggestion: It is recommended to perform purging treatment before processing to ensure uniform mixing.
