Mining Pipe Materials according as MT558.1-2005 standard, use PE80(100)grade high density polyethylene as the basic resin, introduce import compound flame retardant materials and super graphitized carbon black as the function agent. Its usage is convenient, simple and environment-friendly. It's the best material for the mining methane, aeration, water sewage and guniting piping. This material has good processing properties, high mechanical property and low flowingness, is the best mining pipe material.
