First, what are the outdoor water pipe anti-freezing insulation material

1, rubber sponge: soft, cold, flame retardant, shock absorption and other advantages. 2, polyethylene: its production process is more special, but also has the advantages of cold, heat insulation, anti-condensation, etc. 3, composite silicate: belongs to the high efficiency of the thermal insulation material, can withstand high temperatures of seven hundred degrees Celsius. 4, rock wool pipe: very suitable for outdoor chemical industry, ships, petroleum equipment.
