Part I. TPE Introduction

  • 1. Standard definition of TPE

  • According to ISO 1382, Thermoplastic Elastomer is a polymer or a mixture of polymers which doesn’t need vulcanisation or reticulation when processed, but demonstrates similar properties as vulcanised rubber at service temperature. These properties disappear at processing temperature to allow the ulterior process possible, but reappear as the material returns to working temperature.

Part III. Applications of Multiflex

  • 3. Application in development

  • -- To enlarge our sight

  • Flooring application:

    • In Europe and U.S.A, “No PVC” is rather an action than a slogan, certain flooring producers has already engaged in looking for “environment friendly” substitute.

    • This application includes boat deck, hotel floor, and even supermarket floor!

    • Flame Retardance without halogen, which is quite difficult for a normal TPE-s to achieve, is the biggest handicap in this development project.

    • Certain Multiflex samples has already met the requirement, but unfortunately, the raw material supplier stops its supplying.

    • Some new material will be tested soon.

    • Economy is a very important condition for this application.

    • Nowdays, our most aggressive competitor in Europe is TCT, who focus his developing ability on SBS product.
