The conventional sponge tape for automobile wire harnesses is made of high-density flame-retardant sponge as the base material and coated with special pressure-sensitive adhesive after technical treatment, to achieve the effect of shock absorption and noise reduction. The base material of polyurethane (PU) sponge tape is polyether polyol and binary and ternary organic isocyanate, and the adhesive is polyacrylate pressure-sensitive adhesive, with a thickness of 2-5mm. Polyacrylate has strong adhesion and can also adapt to humid environments, high temperatures or heating conditions.✔ Very sound insulation and absorption ✔ Super shock absorption and noise reduction ✔ Strong water resistance ✔ Stable low temperature resistance ✔ Good flame retardancy ✔ Antibacterial ✔ Excellent aging resistance ✔ Strong impact resistance ✔ Aging resistance ✔ Good extensibility☞ There are various thickness, density and color options ☞ It can be rolled or die cut into various shapes ☞ The glue surface shall be flat, and there shall be no lack of glue on the glued surface ☞ High quality materials, the surface is flat and the section is smoothOrdinary PVC tape (high temperature resistant 85 ~ 105 ℃) can be used to bind or fix the harness to meet the requirements. In some special cases, sponge tape needs to be used: 1. When the harness is in direct contact with hard materials, but the harness cannot be completely fixed locally, sponge tape shall be used locally for cushioning, shock absorption, sound absorption and noise reduction. 2. If the harness plug-in (sheath) cannot be completely fixed during loading, sponge tape can be used outside the socket sheath for noise reduction.● Roof harness ● Air conditioning harness ● Door harness ● Casketing, cushioning, vibration control in speakers, electronic components and door frames ● Other places requiring shock absorption and noise reduction Name: Sponge Tape / Foam Tape Material: Polyurethane (PU) Adhesive: Acrylic acid Color: Black, Grey Width, Length and Thickness could be customized
