Multiple thickness options range from 20mm to 50mm. Self-adhesive backing is optional for fast, convenient DIY installation without extra glue. Widely applied for wall soundproofing of recording studios, KTVs and meeting rooms, as well as noise reduction and heat preservation for air ducts, fans and various HVAC machinery.
The unique egg-crate bump surface increases sound contact area, disperses sound waves and consumes acoustic energy inside closed micropores. It effectively eliminates indoor echo and reverberation, greatly improving indoor acoustic environment, far better than flat ordinary foam.
Compact closed-cell structure brings low thermal conductivity, stable heat preservation effect. It repels water penetration and prevents condensation on pipes and equipment surface, avoiding damp damage to facilities.
Formulated with high-efficiency flame retardant raw materials, the product meets B1 fire-resistant standard. It self-extinguishes once leaving open flame, no molten drop spreading, improving safety for indoor and industrial installation.
Made of NBR+PVC composite, the foam boasts outstanding oil resistance, corrosion resistance and anti-aging property. Soft and resilient, it resists cracking or permanent deformation after long-term extrusion and service.
Lightweight texture can be freely cut into any shape with common knives. Optional self-adhesive backing allows direct pasting after peeling protective film, no extra glue required, saving construction time and labor cost.
