Product Description
Hollyseal? PVC foam tapes are made of ultra-low density (80±20kg/m3) very soft closed cell PVC foam with self-adhesive pressure-sensitive adhesive on one side, which provides excellent sealing of air, water, light, etc., gap filling and cushioning of structural components 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. 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
●Flame retardant grade can be customized
●Extremely low density, slow rebound
