Castable polyurethane elastomer (CPUR) is the most important one of the three major processing types of polyurethane elastomer. Its dosage accounts for 6o% ​​of the PUR. It has multiple chemical structures, easy to adjust viscosity, excellent processing technology, and easy investment The advantages of industrial production, easy to use and fast curing are very suitable for making large and complex components. Polyurethane wear-resistant lining is produced by casting polyurethane elastomer technology. The high-pressure polyurethane foam board has high efficiency, and is especially suitable for the absolute heat treatment of large-area and special-shaped objects. High-efficiency spray polyether compound is composed of foaming agent, catalyst, domesticating agent, flame retardant, foaming agent and so on. Polyurethane high-pressure foam board is used for substrates of various shapes, whether it is flat, front or top, whether it is a round, spherical or other complex objects with irregular shapes, can be directly spray foamed, without expensive molds manufacturing cost. Polyurethane board manufacturers contain a large group of polymers with more urethane group characteristic structures on the molecular main chain. It is a polymer material between plastic and rubber. It has a large elongation and hardness range. Wide, wide range of formula adjustment, with excellent wear resistance and mechanical properties. Because of its good fire and moisture resistance, polyurethane composite board is also commonly used in the edge banding core material of other material composite board. The polyurethane edge banding composite board uses high-quality color-coated steel plate as the surface material, and continuous rock wool and glass wool as the core material The density rigid foamed polyurethane is filled with tongue and groove. After high-pressure foaming and curing, it is automatically compacted and made of super-long double cover tape. It has better fireproof and thermal insulation effect than traditional cotton hanging maintenance materials. More durable performance, convenient installation and elegant appearance. Is the pioneer of steel construction maintenance materials.
