Talking about TPE Sealant Strip for Building Outer Window
Jan 05, 2019

  With the development of doors and windows curtain wall industry, people pay more and more attention to the physical properties of doors and windows. Sealant strips for doors and windows play a very important role in the five properties of doors and windows. The quality of sealant strips will affect the performance of doors and windows, and then affect the service life of doors and windows.

  With the development of the industry, the door and window sealant strip has been improved better. The application of EPDM strip has gradually changed from rubber and plastic strip, which was cheap at first, to PVC strip.

  At present, the sealant strip products used to replace EPDM in the market have appeared, and have begun to be applied to engineering practice. That is thermoplastic elastomer material, commonly known as TPE sealant strip, this material not only has the processing properties of thermoplastic plastics, but also has the physical properties of vulcanized rubber. It can be said that it is an advantage combination of plastics and rubber. Its advantages can be summarized as follows:

  1. It can be processed by general thermoplastic forming machine without special processing equipment.

  2. Production efficiency has been greatly improved. It can be vulcanized directly by rubber injection moulding machine, and the time is shortened from 20 minutes to less than 1 minute. Because the vulcanization time is very short, the extruder can be used to vulcanize directly, and the production efficiency is greatly improved.

  3. Easy to recycle and reduce costs. The waste produced in the production process and the final waste can be directly returned to reuse; the used TPE can be simply recycled after recycling, reducing environmental pollution and expanding the source of renewable resources.

  4. energy saving. Most thermoplastic elastomers do not need vulcanization or have short vulcanization time, which can effectively save energy.

  5. Wider application areas. Because TPE has the advantages of both rubber and plastics, it opens up a new application field for door and window curtain wall industry. As a kind of energy-saving and environmental protection sealing material, the development prospects are very promising.
