Our company's HL series flame retardant masterbatches are core materials for coal mine pipelines, including high-content red phosphorus flame retardant masterbatches, single flame retardant polyethylene pipeline special materials, antistatic polyethylene special materials, carbon nanotube antistatic and flame retardant dual-resistance special materials, and colored antistatic and flame retardant special materials. These are high-efficiency flame retardant products made from polyolefin as the carrier resin, through a blending and compounding technology using multiple synergistic flame retardants, primarily employing environmentally friendly and efficient coated phosphorus-based flame retardants, and obtained through a twin-screw extruder for mixing, extrusion, and granulation.

Our company's special antistatic and flame-retardant polyethylene pipe material for coal mines is designed according to the MT558.1-2005 standard. It uses high-density polyethylene as the base resin, compounded with high-performance conductive agents and non-toxic, environmentally friendly microencapsulated red phosphorus. It is a flame-retardant and antistatic polyethylene pipe material made through special micro- dispersion technology and blending process . It is suitable for the production of gas drainage pipes, positive pressure air ducts, negative pressure air ducts, shotcrete pipes, and water supply and drainage pipes in coal mines.
