Several frequently used polyurethane foam materials

Several frequently used polyurethane foam materials

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

Conductive Foam

Conductive foam is encapsulated on 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. Radiation protection materials with different appearances, installation methods, UL levels and shielding efficiency can be given.

According to the raw materials of conductive foam, it can be divided into: aluminum foil cloth foam, conductive fiber cloth foam, electroplated gold cloth foam, carbon cloth foam, etc.

Aluminum platinum foam

Aluminum-platinum foam is made of soft pure aluminum-platinum and glass fiber, and the conductive cloth is replaced by flame-retardant foam. The surface characteristic impedance is lower than 0.016Ω, and it has high-quality metal material shielding performance, and its heat resistance can reach 130 ℃, low cost, and can meet the cost and working pressure requirements of commodities. The conductive foam cotton of aluminum foil cloth has high-quality performance, and the shielding performance is higher than 100 db and high elasticity, which reduces the surface conductive characteristic impedance, resists corrosion, and improves the compatibility of the metal material coating of the RF connector assembly.

CR foam

CR foam is a 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, solvent corrosion resistance and other properties. It is used in various styrene-butadiene rubbers. fully play a key role.

It can be customized according to customer requirements. It is equipped with various imported tapes with good viscosity. The goods are used for communication, computers, electrical products, computing methods, electric toys and various electronic device control boards.

PU polyurethane foam material

PU matching leather is generally the second layer of leather on the back of the cowhide, and the surface is coated with a layer of PU epoxy resin, so it is also called coated cowhide. Low price and high usage rate. 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 level are not inferior to artificial leather.

Both PU leather and real leather products have their own characteristics. PU leather has a beautiful appearance, is convenient for medical care, and is cheap, but it is not resistant to wear and tear and is easily damaged; leather products are more expensive and inconvenient to maintain, but they are durable.

EPEepe pearl cotton

EPE is also known as epe pearl cotton. High pressure polyethylene foam is a non-chemical cross-linked closed pore structure and a new type of environmentally friendly packaging raw material. It consists of thousands of individual bubbles created by the physical polyurethane foam of low density polyethylene resin. It gets rid of the defects of general plastic foam wearing parts, deformation and poor turnover rate. It has the advantages of moisture resistance, shock 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.

Our common die-cut raw material foams are the categories I listed above. The appearance of foams looks simple, but the production process is actually very complicated. There are strict regulations at each stage, especially It is to pay attention to the operation of the die-cutting process.
