3. Used for production of PE coal mine pipe
Antistatic & antiflaming material
Special purpose material for production of HDPE coal mine pipe
Product introduction
It is a new-type product which is developed and produced with various functional additives added into the polyethylene resin through adopting new process and new formula. The material not only possesses excellent physical & mechanical property, but also possesses excellent flame resistant & antistatic properties and good processing property. Coal mining pipes manufactured with the material have good property of smooth inner and outer surface. The material widely applies to the production of pipes used for underground coal mine use water drainage, air supply, guniting and gas drainage, etc. Technical index of the material conforms to MT558.1-2005.
