  Why are thermoplastic elastomers becoming more and more useful and widespread nowadays? Let's look at the advantages of thermoplastic elastomer TPE

  (1) Can be processed by general thermoplastic molding machines, such as injection molding, extrusion molding, blow molding, compression molding, recirculation molding, etc.

  (2) Can be vulcanized by rubber injection molding machine, and the time can be shortened from about 20min to less than 1min.

  (3)Can be vulcanized by press-out machine, with fast press-out speed and short vulcanization time.

  (4)The scraps produced during the production process (escaped burrs, extruded waste rubber) and the final scrap can be directly returned for reuse.

  (5) Used TPE, old products can be reused after simple regeneration, reducing environmental pollution and expanding the source of resource regeneration.

  (6)No vulcanization, saving energy, for example, energy consumption of high-pressure hose production: 188MJ/kg for rubber and 144MJ/kg for TPE, which can save more than 25% energy.

  (7) self-reinforcing, the formula is greatly simplified, so that the influence of the compound on the polymer constraints are greatly reduced, and the quality performance is easier to grasp.

  (8) for the rubber industry to open up new ways to expand the application of rubber products.

  Thermoplastic elastomers are now more and more widely used, in addition to the application of automotive and other industries, the following is introduced: thermoplastic elastomers as medical materials must meet the conditions of what

  Medical materials are in contact with human tissues, blood, body fluids, etc., and some are even permanently implanted in the body. Therefore, these materials must have excellent bio-replaceability (mechanical properties, functionality), biocompatibility and blood compatibility. Thermoplastic elastomers likewise need to meet the following basic conditions.

  (1) Be chemically inert and not react due to contact with body fluids.

  (2) Not cause inflammation and foreign body reactions to human tissues.

  (3) It will not cause cancer.

  (4) Does not cause allergic reactions of a metaplastic nature.

  (5) Good hemocompatibility, non-hemolytic and non-clotting.

  (6) Will not lose physical and mechanical properties such as tensile strength and elasticity even after long-term implantation.

  (7) Can withstand the necessary disinfection measures without deformation.

  (8) Easy to process into the desired, complex shape.
