PU is polyurethane, PU skin is polyurethane skin. Now clothing manufacturers widely use this material to make garments, commonly known as imitation leather clothing.PU is the abbreviation of English ploy urethane, the Chinese name of chemical polyurethane, its quality is also good and bad, and good bags are mostly imported PU skin.
PU leather is usually the second layer of leather on the reverse side. It is coated with a layer of PU resin on the surface. Therefore, it is also called the film skin. Its price is cheaper and its utilization rate is high. With the change of technology, it has also been made into various grades, such as imported two layers of cowhide. Because of its unique technology, stable quality and novel varieties, the price and grade of the top grade leather are no less than that of the top layer of leather.
Conductive foam is coated with conductive cloth on the flame retardant sponge. After a series of treatments, it has good surface conductivity and can be easily fixed on the screen with adhesive tape.
On the device. Shielding materials with different profile shapes, installation methods, UL grades and shielding effectiveness are available.
Conductive foam material can be divided into: aluminum foil cloth foam, conductive fiber cloth foam, gold plated cloth foam, carbon coated cotton foam, etc.
Widely used in PDP TV, LCD display, LCD TV, mobile phones, notebook computers, MP3, communication cabinet, medical equipment and other electronic products, as well as military and aerospace fields.
Aluminum foil foam
Aluminum foil foam is made of soft aluminum foil and glass fiber composite aluminum foil cloth instead of conductive cloth wrapped flame retardant foam. The surface impedance is less than 0.016 Omega, which has excellent shielding performance of metal. Its temperature resistance can reach 130 degrees centigrade. The lower cost can meet the demand of product cost pressure. Aluminum foil conductive foam performance is excellent, shielding performance over 100dB high elasticity, reduce the contact surface conductive impedance corrosion resistance, improve connector compatibility of metal plating.
CR foam is a general purpose special rubber. It has excellent properties such as flame retardant, oil resistant and chemical resistant. It has an important position in all kinds of synthetic rubber.
EPE pearl cotton
EPE is also known as pearl cotton. Polyethylene foam cotton is a non cross linked closed cell structure, and it is a new environment-friendly packaging material. It is made of low density polyethylene (PE) with numerous independent bubbles generated by physical foaming. It overcomes the shortcomings of ordinary foam, such as fragile, deformed and poor recovery. It has many advantages such as water and moisture proof, shockproof, sound insulation, heat preservation, good plasticity, strong toughness, recycling, environmental protection, and strong crashworthiness. It also has good chemical resistance. It is an ideal substitute for traditional packaging materials. It is widely used in packaging electronic products, instruments, computers, acoustics, medical devices, industrial control boxes, lighting, handicrafts, glass, ceramics, household appliances, spraying, furniture, wine and gift packaging, hardware products, toys, melon and fruit, leather shoes, packaging, daily necessities and other products. With the addition of antistatic agents and flame retardants, its superior performance is achieved.
EPE pearl cotton is also widely used in the elastic lining of handbags and bags, industrial production of sound insulation, heat insulation materials, agricultural insulation materials, floating equipment for aquaculture, protective pads for sporting goods, aquatic life rescue equipment, family, guesthouse floor decoration, cushion and so on. Its pipes are widely used in air conditioning, children's cars, children's toys, furniture and other industries.
EPE and all kinds of textile adhesive products are good interior decoration materials for all kinds of vehicles and living rooms. EPE and aluminum foil or aluminized film composite products have excellent anti infrared ultraviolet ability. They are substitutes for some chemical equipment cold storage and camping equipment sunshade.
