The Difference Between PU Foam Sealing Strip And Traditional Seal Strip Is As Follows
May 12, 2018

The difference between PU foam sealing strip and traditional seal strip is as follows.

1) the use of advanced thermoplastic rubber Santoprene ® (TPE) or nitrile butadiene rubber and chlorosulfonated polyethylene composite with;

2) characteristics of ozone resistance, resistance to ultraviolet optical performance, good resistance to chemical solvent, using temperature range (60 ℃ to 135 ℃);

3) with strong tensile, tear resistance performance, temperature of use between - 10 ℃ -- 150 ℃ after the number of millions of music scratch will not burst;

4) after compression, the original shape can be restored quickly. Even in the harsh environment, it can maintain its original flexibility.

5) environmental protection rubber and plastic compound rubber, non-toxic, environmental protection, no pollution.

The traditional seal strip, due to the use of waste, substitute plasticizer and high filling amount, makes the rubber strip elastic, easy to be hard, and has a prickly smell, easy to migrate to make the frame material yellow, and the service life is short. Traditional sealing strips contain halogens, which contain heavy metals in the stabilizer, so it is not conducive to environmental protection. Therefore, traditional seal strips are eliminated or restricted in developed countries and in China.
