Versatile Open Cell Polyethylene Acoustic Foam with High Processability and Temperature Tolerance
Acoustic Absorption Foam -Open Cell Polyethylene Acoustic Foam - CTF
Acoustic Absorption Foam (TGD 3510 PO Foam) is a foam product obtained through the processes of blending polyethylene with foaming agents and auxiliaries, followed by extrusion and foaming. Further processing includes laminating with aluminum film and adhesive backing to produce the final acoustic foam.
Noted for its corrosion resistance, sound absorption, and thermal insulation properties, the foam is predominantly utilized in noise-reduction applications, such as in automobiles, high-speed trains, and large-scale air conditioning systems.
Features:
- Lightweight & Eco-friendly: Environmentally friendly with chemical resistance.
- Acoustic Performance: High open-cell structure for effective sound absorption.
- Thermal Insulation: Low thermal conductivity (≤0.04 W/mk) ensures efficient insulation.
- Processability: Compatible for bonding and die-cutting, enhancing manufacturing versatility.
- Temperature Tolerance: Operates effectively between -50°C and 80°C.
- Safety: UL94 HF-1 certified for fire retardancy, ensuring safety in use.
