Product Description
Hollyseal® PVC foam tapes are made of soft, closed-cell PVC foam of 130±20 kg/m3 density with a pressure-sensitive adhesive on one side, which provides excellent sealing of air, water, light, etc., gap-filling and shock absorption for the installation of structural components at various compression levels. In addition, the density, hardness, and compression rebound of the foam can be adjusted to provide performance in a variety of applications. It is suitable for various applications such as automotive sheet metal damping and sealing, water tank sealing, HVAC sealing, door and window weather stripping, electrical and electronic damping and sealing, power battery sealing and cushioning, die-cutting gaskets, etc. Dustproof, waterproof, 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 Structure
Product Features
●Excellent vibration damping 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)
