Commonly used foam types on the market

 

Foam is a polymer with many small cells. The solid phase is the polymer substrate. The small cells are filled with other vapors. The polyurethane foaming speed is low and the relative density is high. The key is for shock absorption. Possess sealing effect.

 

Polyurethane foam material

Polyurethane foam has high-quality expansion and high resilience, moisture resistance and acid resistance, and can thoroughly meet various environmental protection regulations such as airtightness and energy absorption. It can prevent the actual operation of self-adhesive according to the regulations of single-layer polyurethane resin, and has a higher performance and price comparison. It uses PET or printing paper as the supporting point to ensure the smoothness of the foam. It is suitable for various die-cutting production processes. .

 

PU polyurethane foam material

The surface of PU polyurethane foam is coated with a layer of PU epoxy resin. The price is low and the utilization rate is high. With the transformation of processing technology, it has also been made into various types, such as imported two-layer cowhide. Because of its distinctive processing technology, stable quality, novel types and other characteristics, it is a high-end leather product at this stage. The price and grade are not inferior to artificial leather.

Both PU leather and real leather products have their own characteristics. PU leather is beautiful in appearance, convenient for medical care, cheap, but not resistant to wear and tear, and easy to damage; leather products are more expensive, inconvenient to maintain, but durable.

 

Conductive foam

The conductive foam is encapsulated on the flame-retardant sponge with conductive cloth. After a series of solutions, it has excellent surface conductivity and can be easily fixed on machinery and equipment and shielded with tape.

The raw materials of conductive foam can be divided into: aluminum foil cloth foam, conductive fiber cloth foam, electroplated gold cloth foam, carbon cloth foam and so on.

 

Aluminum platinum foam

Aluminum platinum foam is made of soft pure aluminum platinum and glass fiber, using flame-retardant foam plastic instead of conductive cloth for encapsulation. The surface characteristic impedance is lower than 0.016Ω. It has high-quality metal material shielding performance, its heat resistance can reach 130℃, low cost, aluminum foil cloth conductive foam cotton has high-quality performance, shielding performance is higher than 100 db, and high elasticity, reducing the surface Conductive characteristic impedance, anti-corrosion, improve the compatibility of the metal material coating of the RF connector assembly.

 

CR foam

CR foam is a kind of general-purpose special rubber. It not only has the excellent physical properties of general vulcanized rubber, but also has high-quality flame retardancy, acid and alkali resistance, and solvent corrosion resistance. It is in a variety of styrene butadiene rubber Give full play to the key functions.

 

Can be customized according to customer requirements, equipped with a variety of imported tapes, good adhesion, CR foam is used for communication, computers, electrical products, calculation methods, electric toys and various electronic device control panels.

 

EPEepe pearl cotton

EPE is also called epe pearl cotton. High-pressure polyethylene foam is a non-chemical cross-linked closed pore structure, and it is a new type of environmentally friendly packaging raw material. It is composed of thousands of individual bubbles caused by the physical polyurethane foaming of a low-density polyethylene resin. Get rid of the defects of general plastic foam vulnerable parts, deformation, and poor transaction rate. It has the advantages of moisture resistance, earthquake resistance, sound insulation and noise reduction, heat insulation, good plastic performance, strong ductility, recyclability, environmental protection, impact resistance, etc., and its excellent acid resistance. It is an ideal substitute for traditional packaging products.
