Long life polyurethane insulation boards, large carrying capacity. Due to the use of polyurethane elastic rope sieve skeleton material, coupled with polyurethane itself has a very high elastic modulus, high strength to absorb impact, high abrasion polyurethane board manufacturers, which has a high tensile strength polyurethane insulation sheet wholesale, its carrying capacity is more than 2.5 times the rubber sieve. Its life compared with ordinary metal sieve increase 8-10 times that of stainless steel screen surface is three times the price of polyurethane insulation sheet is 3.9 times of natural rubber, is the world's best wear resistance of the screen surface material . Polyurethane sieve material is a polymer organic production of elastomers, with excellent abrasion resistance, flex resistance, carrying capacity. Polyurethane sieve production of raw materials through a special treatment to ensure the long-term under alternating loads never delamination. Improve the flame retardant properties of polyurethane material, there are two methods. One flame retardant in the material. Currently used more halogen and phosphorus flame retardant, the presence of dioxin emissions during combustion, increasing the toxic fumes. If pure phosphorus flame retardants, inorganic nanocomposite flame retardants and other species, the polyurethane retardant building materials, low toxicity, low smoke effect. PU board manufacturers, Tsinghua plastic (certified), polyurethane insulation sheet provided by the Engineering Plastics Co., Tsinghua ShangYinXian. ShangYinXian Tsinghua Engineering Plastics Co. (www.tyqhgc.com) is Anyang, other leaders, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. Tsinghua engineering leadership with the staff warmly welcome all inquiries negotiations to create a better future Tsinghua engineering.
