Characteristics
Divided into foam structure: open foam and closed cell foam.
Open-cell foam: soft texture, high water absorption, high compression rate, suitable for sound-absorbing sealing applications, such as earphone compression sponge, air-conditioning seal, etc.
Closed-cell foamed cotton: independent foaming, low compression residual rate, low water absorption, heat insulation and cushioning performance is good, dust-proof, suitable for electronic products, sealing dust, waterproof, shock absorption, etc.
Application Area
Shock absorption foam: component loss prevention, shock absorption, motor damping
Dustproof foam: dustproof between lens and LCD, Camera
Sound insulation and sound absorption: combined with screen mesh for Speaker
Conductive foam: used to fill conductive shielding.
Gasket and filling: shock absorption, skid resistance, filling.
