What’s the fiber materia of silt sock fabric HDPE?
HDPE High-density polyethylene (HDPE) is an environmentally friendly material, which is resistant to acids and bases, organic solvents, excellent electrical insulation, low temperature, can still maintain a certain degree of toughness. Surface hardness, tensile strength, rigidity, and other mechanical strength are very high. High density polyethylene (HDPE) is a thermoplastic polyolefin produced by copolymerization of ethylene. HDPE is typically manufactured using the Ziegler-Natta polymerization process and is characterized by the absence of branched chains in the molecular chain, resulting in a regular molecular chain arrangement and a high density. The process uses ethylene as the raw material in a tubular or kettle-type low-pressure reactor and initiates the polymerization reaction with oxygen or organic peroxide as initiator. Low water absorption; poor aging resistance, which can be greatly improved by adding antioxidants and UV absorbers to the resin. “Aging resistance can be enhanced by adding antioxidants and UV stabilizers to the resin.” Basic Properties High-density polyethylene (HDPE) raw material is an opaque white waxy material, lighter than water, specific gravity of 0.941 ~ 0.960, soft and tough, elongation, non-toxic, tasteless. Melting point is 142℃, decomposition temperature is 300℃. Flammable, can continue to burn after leaving the fire, the upper end of the […]
