2023-03-09 mf_dqsh 1749




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 (1-25mm), hardness, and compression rebound of the foam can be adjusted to provide performance for various application scenarios.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
