Product Description
Hollyseal® PVC foam tapes are made of medium rigid closed-cell PVC foam with a density of 250±30 kg/m3 and self-adhesive pressure sensitive adhesive on both sides, which provides excellent sealing of air, water, light and other substances, gap filling and shock absorption for structural component installation at different 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. for dustproof, waterproof, damping, cushioning, sound insulation, heat insulation, etc. With transparent PET film on the surface, it is more waterproof compared to the release paper and not easy to break and shatter when used.
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
●Sealing water, dust and air at 10% compression
●Perfect combination of flexibility, compliance and high strength abrasion resistance
●Excellent UV resistance and weather resistance
●Conforms to curves and irregular shapes
●Excellent vibration and sound dampening properties
●Customizable flame retardant rating (UL-94 V0; BS476:Part7:1997 Class1)
●Dimensionally stable under compression
●Provides insulating properties
