Hollyseal® Soft Microcellular Crust Door and Window Sealing PVC Foam

Hollyseal® PVC foam is a closed-cell PVC foam designed to provide an economical solution for sealing light, air, moisture, etc. The foam can be adjusted in terms of density (110kg/m³ to 500kg/m³), softness (Shore 00 5° to 99°), and resilience to provide p


Product Description

Hollyseal® low and medium density foam is a soft, closed-cell PVC foam that provides excellent sealing against water, dust, light and other substances at various compression levels, and also provides cushioning and shock absorption during the installation of structural components. The surface of the foam can be protected with self-adhesive pressure-sensitive adhesive, paper or release film according to the needs of use. In addition, the density (180±20 kg/m³), thickness (1-25 mm), 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.
