Artificial grass yarn is now more widely used raw material is polyethylene (PE), especially in the production of low-density polyethylene grass silk better. Polyethylene according to the polymerization method, high and low molecular weight, different chain structures, from high density polyethylene, low density polyethylene and linear low density polyethylene. LDPE (LOW DENSITY POLYETHYLENE, LDPE), commonly known as high-pressure polyethylene artificial grass, due to lower density, the softest material, mainly used in plastic bags, agricultural film. High-density polyethylene (HIGH DENSITY POLYETHYLENE artificial turf soccer field, HDPE), commonly known as the low-pressure polyethylene, with LDPE and LLDPE comparison, there are higher standards of temperature, oil resistance, vapor permeability and resistance to environmental stress cracking resistance, in addition to electricity insulation resistance and impact resistance and cold can be a good artificial turf football field, mainly used in blow molding, injection molding and other fields. Linear low density polyethylene (LINEAR LOW DENSITY POLYETHYLENE, LLDPE), is a copolymer of ethylene and a small amount of high-level Α- olefin polymerization in the presence of a catalyst. LLDPE and LDPE similar appearance, some transparency is poor, but the surface gloss, low temperature toughness, high modulus, flexural stress crack resistance and artificial turf football field construction, better impact strength at low temperatures and so on. Linear low density polyethylene and low-density polyethylene similar performance, but a number of characteristics of both high-density polyethylene, combined with the production of low energy consumption, and therefore extremely rapid development, has become one of the new synthetic resin most impressive. With the change of time, artificial turf industry in the early 1980s before being open to the rapid development in the world. In the early 1990s, China started the artificial turf market, sports artificial floor in the country began to promote the use of the course. With the movement of the artificial turf in the country to promote the use of large numbers of foreign fast artificial turf brands tore into the Chinese market, in this environment, the country will also gradually nurture a number of national sports artificial turf manufacturers. Artificial turf stadium construction, artificial grass, Camry sports provided by the Dongguan City Camry sports facilities Engineering Limited.
