China sound absorption thermal insulation sheet Supplier, Factories

Kingflex acoustic insulation sheet is open cell elastomeric foam,based on synthetic rubber (NBR). It is a vinyl sound barrier mat loaded with naturally occurring minerals. This Sound Insulating Sheet is free of lead, unrefined aromatic oils and bitumen. It is excellent at reducing the transmission of airborne sound and in enhancing the insertion loss performance of pipe insulation by providing a barrier to noise.

Acoustic Sheet Packaging and Quality Control
Frequently Asked Questions (FAQ)
What are the primary applications of this sound absorbing insulation sheet?
This material is designed for universal sound absorption, making it ideal for HVAC Ducts, Air Handling Systems, Plant Rooms, and Architectural Acoustics.
How does this product prevent corrosion under insulation (CUI)?
The advanced open-cell design and thermal insulation properties minimize moisture build-up and stress concentration, significantly reducing the risks related to corrosion under insulation.
What safety certifications does the insulation sheet meet?
The insulation sheet meets Class 1 BS476 Part 7 and V0 UL 94 standards. It is fireproof, self-extinguishing, produces no flaming drops, and does not propagate fire.
Is this insulation safe for indoor air quality?
Yes, it is completely non-fibrous and fiber-free. It prevents fiber migration and dust dispersion, ensuring healthy air quality in indoor and commercial environments.
What is the difference between the low density and high density variations?
Low-density sheets (≥160 KG/M³) offer lower thermal conductivity, while high-density sheets (≥240 KG/M³) provide higher tensile strength (90-150 kPa) and structural stretch rates (60-80%), making them ideal for heavy-duty dampening applications.
What is the operational temperature range of these sheets?
Both density classes operate reliably and retain their physical integrity within a temperature range of -20℃ to +85℃.
