What are the types of foam
Foam can be divided into the following types according to the different materials:
1. PU foam (polyurethane) pu foam is made of polyurethane foam. 2, conductive foam
Conductive foam is coated with conductive cloth on flame retardant sponge. After a series of treatments, it has good surface conductivity. It can be easily fixed on the device to be shielded with adhesive tape. Shielding materials are available in different profile shapes, mounting methods, UL grades and shielding efficiency.
Conductive foam according to the material can be divided into: aluminum foil fabric foam, conductive fiber fabric foam, gold plated fabric foam, charcoal plated fabric foam, etc. 3. Aluminum foil foam
Aluminum foil foam is made of soft pure aluminum foil and glass fiber composite aluminum foil cloth instead of conductive cloth wrapped flame retardant foam. Surface impedance ≤0.016Ω, with excellent metal shielding performance, its temperature resistance up to 130℃, low cost, can meet the needs of product cost pressure. Aluminum foil cloth conductive foam excellent performance, shielding performance more than 100db high elasticity, reduce the contact surface conductive impedance corrosion resistance, improve the connector assembly metal coating compatibility. 4. korel foam
Korel (microporous polyurethane foam) is a high-tech foam with excellent compressibility, high resilience, moisture resistance and chemical resistance produced by Saint-Gobain Group in France. This foam is divided into K series and E series. And can fully meet the needs of a sealed, energy-absorbing environment. It can stick pressure sensitive glue on one side according to the demand, which avoids your glue operation and has a higher cost performance. PET-FLLM or paper as the support surface ensures the flatness of foam, which is suitable for all kinds of die cutting processing.
