A Beijing-based polymer polyurethane panels suppliers / polyurethane insulation board manufacturers DLA polyurethane macromolecular chain containing urethane-type repeating structural units, called poly-amino acid ester, the English called polyurethane, abbreviated PU or PUR. PU is a polyisocyanate with a polyether or polyester polyols reflected in a certain proportion of products. PU and PU sandwich panel color steel composite formation, mainly for industrial, civil construction insulation systems, has become the most widely used products PU system. Performance Performance PU elastomers: performance PU elastomer molding polyol synthesis between the performance of PU elastomers differ slightly. High mechanical properties of polyester PU, the oil is good, but poor water resistance; low temperature resistance and hydrolysis resistance polyether PU is better than polyester, but oil resistance, mechanical properties slightly worse. The mechanical properties of PU: PU elastomer hardness range is wide, can Shore A10 to D80, high elongation at break of 600% ~ 800%. The maximum Shore hardness of natural rubber only A70, elongation at break of 550%. Higher tear strength of the PU elastomer, large 2 ~ 5 times than natural rubber. Resilient PU elastomers, good damping effect. Abrasion PU elastomers, good for 3 ~ 10 times the natural rubber. First, the raw material composition and product testing starting polyether polyols, polyether polyols industrial products; isocyanate (industrial), curing agent, flame retardant additives, antistatic additives, pigments, reinforcing material.
