Thermoplastic elastomer (TPE) material is a prominent new type of environmental protection material. It is mainly divided into polyolefins (TPV, TPO), polyurethanes (TPU), polyesters (TPEE), polyvinyl chloride (TPVC), polyamides (TPAE) and other types of thermoplastic elastomers.
The main products used on the sealing strips are polyolefin (TPV, TPO) thermoplastic elastomers. The friction coefficient of this type of material and glass is small and the wear resistance is good. It can be used as the guide material for automotive glass guide grooves, door glass inner and outer sealing strips, and some auxiliary sealing strips.
The brutal growth and vicious competition of rubber foam seal companies have brought a tremendous negative impact on the rubber and plastics industry. The industry users and the media began to question the actual effect of
foam rubber sealing strip. The original advocacy became cautious. Market sales also slowed down for several years, and even some regions experienced a drop in sales. While domestic rubber foam seals are facing difficulties, foreign brands of rubber foam seals have secretly entered the Chinese market. Of course, despite the chaotic state of the market, major domestic brands are moving forward and gradually find their own. Direction of development.
Foam seal is a kind of sealing strip that uses the characteristics of certain data to make the internal pores appear. It is divided into EPDM foam seals, silicone foam seals, and PU foam seals. The foam sealing strip is molded by microwave vulcanization technology. The surface of the foam seal is beautiful and free from scratches. It has excellent elasticity and anti-shrinkage deformation, and it has excellent anti-aging function. In addition, the flame retardant function is excellent, low smoke and low toxicity. And the product features stable, high-precision scale.
