TPE advantages and disadvantages

- Jun 21, 2019-

TPE Advantages:

1.It can be machined by a general thermoplastic molding machine,don't need special processing equipment.

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

3.The vulcanization can be formed by an extruder, and the extrusion speed is fast and the vulcanization time is short.

4.The waste generated in the production process can be directly returned for reuse.

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

6.Energy saving. Most of the thermoplastic elastomers do not need vulcanization or vulcanization for a short time, which can effectively save energy. Take the production of high pressure hose as an example: rubber is 188MJ/kg and TPE is 144MJ/kg, which can save more than 25% energy.

7.The self-reinforcing property is large, and the formula is greatly simplified, so that the influence of the compounding agent on the polymer is greatly reduced, and the quality performance is easier to grasp.

8.Open up new avenues for the rubber industry and expand the application of rubber products

TPE Disadvantages:

The heat resistance of TPE is not as good as that of rubber. As the temperature rises, the physical properties decrease greatly, so the scope of application is limited. At the same time, the compression deformation, springback, and durability are equivalent to rubber, and the price is often higher than that of similar rubber.
