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 artificial turf soccer field, 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, 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, electrical insulation and anti addition good impact resistance and cold resistance, 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 look like artificial turf soccer field, more transparency is poor, but good surface gloss, low temperature toughness, high modulus, flexural stress crack resistance and impact strength at low temperatures better advantages. 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. Beginning in the 1990s, China started the artificial turf market and development, China's artificial grass yarn market is divided into three stages artificial turf football field, the first stage, the domestic manufacturers of artificial turf began to appear, but the market is mainly for all imports artificial turf. The second phase, the number of domestic enterprises have gradually increased artificial turf, grass silk imports from abroad, at home knitting process, and the end of the import substitution era lawn. Artificial grass fibers while domestic companies are quietly breathless developed; at this stage of the grass fibers and Chinese companies began to explore the global market lawn, and gradually into Europe, the Middle East and other markets. The third stage, the domestic scale, the strength of lawn companies have the ability to produce grass fibers into the independent research stage. Artificial turf soccer field, Camry sports (certified), artificial turf provided by the Dongguan City Camry sports facilities Engineering Limited. Dongguan City Camry Sports Facilities Engineering Co., Ltd. (www.kmtyss.com) is Dongguan, related products leader, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs.
