PU is polyurethane, PU leather is the skin of polyurethane. Nowadays, garment manufacturers use this material to produce garments, commonly known as imitation leather garments. PU is the abbreviation of English loyal urethane, chemical Chinese name polyurethane has good quality, good bag More imported PU leather;

PU leather is a second layer of leather which is generally cowhide on the reverse side. It is coated with a layer of PU resin on the surface, so it is also called film cowhide. Its price is cheaper and its utilization rate is high. With the change of the process, it is also made into various grades, such as imported two-layer cowhide. Due to its unique craftsmanship, stable quality and novel variety, it is the current high-grade leather, and its price and grade are no less than the top layer of leather.

PU leather and leather bags have their own characteristics. PU bags have beautiful appearance, good care, low price, but not wearable and easy to break; leather is expensive, troublesome, but durable.

Conductive foam wraps the conductive cloth on the flame-retardant sponge. After a series of treatments, it has good surface conductivity, which can be easily fixed with the adhesive tape.

Cover the device. Shielding materials with different cross-sectional shapes, mounting methods, UL ratings and shielding effectiveness are available.

Conductive foam can be divided into: aluminum foil cloth foam, conductive fiber cloth foam, gold-plated cloth foam, carbon coated cloth foam, etc.

Conductive foam features and advantages

RoHS compliant

Improved Z-axis resistivity improves shielding performance to over 90dB over a wide frequency range

Applicable thickness 0.039" (1mm), 0.060" (1.5mm), 0.079" (2 mm), 0.098" (2.5 mm), 0.125" (3.2mm), width 0.250" (6.4mm)

Large compression range, up to 60% of original thickness

Also has UL94 HB and V0 flame retardant rating

Suitable for a variety of standard configurations, including D-subs, USB port, IEEE 1394, SCSI and RJ 11. (also for thin sheets and rectangular shapes)

Can be die cut into the desired shape

Punching I/O, rectangular liners and panel liners are available with or without conductive adhesive

Low residual deformation guarantees long-term performance of the product

Widely used in PDP TV, LCD display, LCD TV, mobile phone, notebook computer, MP3, communication cabinet, medical equipment and other electronic products as well as military and aerospace

Aluminum foil foam is an aluminum foil cloth made of soft aluminum foil and glass fiber instead of conductive cloth wrapped flame retardant foam. The surface impedance is ≤0.016Ω, with excellent shielding performance of metal, its temperature resistance can reach 130°C, and the lower cost can meet the demand of product cost pressure. The aluminum foil cloth has excellent performance of conductive foam, and the shielding performance exceeds 100db high elasticity, which reduces the conductive impedance of the contact surface and resists corrosion, and improves the compatibility of the metal plating of the connector assembly.

CR foam is a general-purpose special rubber. In addition to the good physical properties of general rubber, it also has excellent properties such as flame resistance, oil resistance and chemical resistance, so it plays an important role in various synthetic rubbers.

Main features:

1, with excellent sealing, to avoid gas release and atomization.

2, excellent resistance to compression deformation, that is, the elasticity is durable, can ensure that the parts have long-term shock protection.

3, with flame retardant, no harmful toxic substances, no residue, no pollution, no corrosive to metal.

4, can be used in a variety of temperature ranges. It can be used from minus 40 degrees Celsius to 90 degrees.

5, the surface has excellent wettability, easy to bond, easy to make, easy to die.

6. Engineered polyurethane formulations offer a wide range of moduli - 2-90 psi @ 25% deviation - to meet more design flexibility requirements.

Can be customized according to customer requirements, fit a variety of imported tape, good viscosity, products used in communications. Computers. Household appliances. Calculators. Electronic toys and various electronic controllers and other fields


EPE is also known as pearl cotton. Polyethylene foamed cotton is a non-crosslinked closed cell structure and is a new environmentally friendly packaging material. It consists of low density polyethylene glycol by physical foaming to produce a myriad of independent bubbles. It overcomes the shortcomings of common styrofoam, such as fragility, deformation and poor recovery. It has many advantages such as water-proof, moisture-proof, shock-proof, sound-proof, heat preservation, good plasticity, toughness, recycling, environmental protection, strong impact resistance, etc. It also has good chemical resistance. It is an ideal substitute for traditional packaging materials. Widely used in electronic appliances, instrumentation, computers, audio, medical equipment, industrial control chassis, lighting, crafts, glass, ceramics, home appliances, painting, furniture, alcohol and gift packaging, hardware products, toys, fruits, leather shoes Packaging of various products such as packaging and daily necessities. After adding antistatic agent and flame retardant, it shows its excellent performance.

EPE pearl cotton is also widely used in the elastic lining of handbags and bags, industrial production of sound insulation, insulation materials, agricultural insulation materials, aquaculture floating equipment, sports equipment protection mats, waterborne life-saving equipment, home, hotel floor decoration , padding, etc. Its pipes are widely used in air conditioners, baby carriages, children's toys, furniture and other industries.

Adhesive products of EPE and various fabrics are good interior finish materials for a variety of vehicles and homes. The composite product of EPE and aluminum foil or aluminized film has excellent anti-infrared ultraviolet light ability, and is a substitute for some chemical equipment refrigerators and camping equipment.
