[Classification of foam] Foam is divided into PU foam, anti-static foam, conductive foam, EPE, EPP, flame-retardant foam, anti-static EPE, PORON, CR, EVA, bridge PE, SBR, EPDM, XPE foam and IXPE foam, etc.
[The performance of the foam can be customized according to the needs of customers]
1. It is flexible and light in weight.
2. The anti-corrosion nickel coating can prevent electrochemical corrosion.
3. Low surface contact resistance.
4. Fast pressure sensitive fixation.
5. Customers can specify the length.
6. Numerous cross-section options.
7. UL class fire protection.
Introduction of common types of foam:
EVA foam and resin are characterized by good softness, rubber-like elasticity, good flexibility at -50°C, good transparency and surface gloss, good chemical stability, anti-aging and Good ozone resistance and non-toxic. Good blending with fillers, good coloring and molding processability.
EPE is also called pearl cotton. Polyethylene foamed cotton is a non-crosslinked closed-cell structure and is a new type of environmentally friendly packaging material. It has many advantages such as water-proof and moisture-proof, shockproof, sound insulation, heat preservation, good plasticity, strong toughness, recycling, environmental protection, and strong impact resistance. It also has good chemical resistance. Widely used in electronic appliances, instrumentation, computers, audio, medical equipment, industrial control cabinets, lighting, handicrafts, glass, ceramics, home appliances, spraying, furniture, wine and gift packaging, hardware products, toys, fruits, and leather shoes. Packaging, daily necessities and other products packaging. After adding anti-static agent and flame retardant, it shows its excellent performance.
Aluminum foil foam is made of flexible pure aluminum foil and glass fiber composite aluminum foil cloth instead of conductive cloth to wrap flame retardant foam. The surface impedance is less than or equal to 0.016Ω. It has excellent shielding performance of metal, and its temperature resistance can reach 130°C. The lower cost can meet the demand of product cost pressure.
CR foam is a general-purpose special rubber. In addition to the good physical properties of general rubber, it also has excellent characteristics such as flame resistance, oil resistance, and chemical corrosion resistance, so it occupies an important position in various synthetic rubbers.
EPP: Polypropylene plastic foam material is a highly crystalline polymer/gas composite material with excellent performance. With its unique EPP foam, EPP applications are becoming more and more extensive. IT products, electronic communication equipment, liquid crystal displays, plasma color TVs, precision electronic components, precision instruments and meters have all begun to use EPP as packaging materials in large quantities. The special and superior performance has become the fastest growing environmental protection new type of pressure-resistant cushioning and thermal insulation material.
Sponge is a porous material with good water absorption and can be used to clean things. Mix the foaming resin, foaming aids and binder resin (to make the finished product adhesive). The main sponges are: industrial sponges: foamed cotton, shaped cotton, rubber cotton, memory cotton, etc. Chemical sponge, soft polyurethane foam rubber.
