Product Description 

Hollyseal® low density foam is a soft, closed-cell PVC foam that provides excellent sealing against air, water, light and other substances at various compression levels, as well as cushioning and shock absorption for the installation of structural components. The surface of the foam can be protected by self-adhesive pressure-sensitive adhesive, paper or release film according to the needs of use. In addition, the density (130±20 kg/m3), thickness (1.5-25mm), hardness, and compression rebound of the foam can be adjusted to provide performance for a variety of applications. It is suitable for various applications such as automotive sheet metal vibration damping sealing, water tank sealing, HVAC sealing, door and window roof weather stripping, electrical and electronic vibration damping sealing, power battery sealing and cushioning, die-cutting gaskets, etc. for dustproof, waterproof, vibration damping, cushioning, sound insulation, heat insulation, etc.


The main types of PVC foam we produce, they are:

●Fast recovery foam - material recovers immediately after compression

Slow recovery PVC foam - ideal for filling irregular surfaces


Product Features

●Excellent shock absorption and sound insulation performance

Good compression rebound and adhesion

●Highly conformable to curves and irregular shapes

●Excellent UV resistance and weather resistance

●Sealing water, dust and air can be achieved at 30% compression

Release paper on non-adhesive surface reduces dimensional changes during application

●Flame retardant rating can be customized (UL94 V-0; BS476:Part7:1997 Class1)
