Types and Characteristics of Foam Sealing Strips
Dec 01, 2018

     Foam sealing strip is a kind of sealing strip which makes use of the characteristics of some materials to make its internal air holes appear by processing. It is divided into EPDM foam sealing strip, silica gel foam sealing strip and PU foam sealing strip. Foaming sealing strip is a kind of sealing strip which makes use of the characteristics of some materials to make its internal air holes appear by processing. It is divided into EPDM foam sealing strip, silica gel foam sealing strip and PU foam sealing strip. The foamed sealing strip is formed by microwave vulcanization process at one time, with a smooth and beautiful surface and no contact marks. It has good elasticity and compressive deformation resistance, and excellent aging resistance. Excellent flame retardant performance, low smoke and low toxicity, stable product performance, high dimensional accuracy.


  Characteristics of foamed seals:

  1. The foamed sealing strip is light, strong and tough, and has strong toughness.

  2. Low thermal insulation and conductivity, with superior thermal insulation.

  3. The foamed sealing strip has independent bubble structure and low water absorption.

  4. It has excellent cushioning and impact resistance and can be used as cushioning material.

  5. Foamed seals have excellent weatherability. EPDM sponge can pass ozone resistance test (50 PPHM * 40.C * 72 hours).
