Rigid Polyurethane Plastic Extrusion Profiles For Sound Insulation

Rigid Polyurethane Extrusion Light In Weight Excellent Sound Insulation

Dectription

Polyurethane (PU), the full name of polyurethane, is a polymer compound. It was made by Otto Bayer in 1937. Polyurethane is divided into two categories: polyester type and polyether type. They can be made into polyurethane plastics (mainly foamed plastics), polyurethane fibers (called spandex in China), polyurethane rubbers and elastomers.

Soft polyurethane is mainly a thermoplastic linear structure, which has better stability, chemical resistance, resilience and mechanical properties than PVC foam materials, and has less compression deformation. It has good thermal insulation, sound insulation, shock resistance and anti-virus performance. Therefore, it is used as packaging, sound insulation, filter material. Rigid polyurethane plastic is light in weight, excellent in sound insulation and thermal insulation, chemical resistance, good electrical properties, easy processing, and low water absorption. It is mainly used in construction, automobile, aviation industry, thermal insulation structural materials. The performance of polyurethane elastomer is between plastic and rubber, oil resistance, wear resistance, low temperature resistance, aging resistance, high hardness and elasticity. Mainly used in shoe industry and medical industry. Polyurethane can also be used to make adhesives, coatings, synthetic leather, etc.

Polyurethane appeared in the 1930s. After nearly 80 years of technological development, this material has been widely used in the field of home furnishing, construction, daily necessities, transportation, and home appliances. 
Polyurethane (PU) was first developed by German scientists in the 1930s. German scientists polycondensed liquid isocyanate and liquid polyether or glycol polyester to form a new type of material. Polyolefin materials are not the same, scientists named it polyurethane. With the end of World War II, the chemical manufacturing industry in the United States flourished, and in the 1950s, flexible polyurethane foam was synthesized, which was an important milestone in the chemical industry at that time, and provided a solid foundation for the future development of the polyurethane industry. technical basis.

Products Produced

Manufacturers mold plastic pallets into an array of shapes, including: profiles, PVC channels, plastic strips, and plastic tubing. They use shapes like these to create a wide range of finished products, such as: engine components, auto exterior trim (decorative or functional), electronic housings, fencing, window frames, wire insulation, deck railings, plastic films, thermoplastic coatings and more.

ABS extrusion profiles can be obtained by the extrusion process of Acrylonitrile Butadiene Styrene with lightweight and high impact resistance. The most advantage of the extruded ABS profile is the excellent homogeneous glossy and matte surface. Also, ABS profiles can also be co-extruded with some special types of rubber or PMMA. It is also possible to obtain extruded profiles that include a rigid and flexible section. So it is also widely used for automotive, appliances, furnishings, construction, toys.
