Can PE flame-retardant master batch be used for PE flame-retardant pipes?

The PE flame-retardant pipe is a high-tech product, which is processed and formed by extrusion with high-quality imported high-density polyethylene as the main raw material and adding appropriate additives. This product has the characteristics of corrosion resistance, impact resistance, high mechanical strength, long service life, excellent electrical insulation performance, etc., and can be widely used in fields such as buried high-voltage cables and protection sleeves for street lamp cables. 

Usage suggestions and precautions for PE flame-retardant master batch: 

A. Suitable processing temperature: LDPE: (180-200℃); HDPE: (190-220℃). 

B. Adding an appropriate amount of 15-20% talcum powder can reduce the cost and play a reinforcing role (Note: The addition amount shall not exceed 20%, and the talcum powder master batch has a better effect; Barium sulfate must not be added, otherwise the flame-retardant effect will be lost). 

C. The melting points of different new PE materials are different, so the addition ratio of the flame retardant will also vary slightly. When it exceeds the optimal addition ratio, the greater the addition amount, the worse the flame-retardant effect will be (Note: It is required to be new PE materials, and waste or old materials are not allowed).
