Product Description

Introduction to Thermoplastic Elastomer Sealing Strip

Thermoplastic elastomer TPE/TPR, also known as artificial rubber or synthetic rubber sealing strip. Its products not only have the high elasticity, aging resistance, and oil resistance of traditional cross-linked vulcanized rubber, but also have the characteristics of convenient processing and wide processing methods for ordinary plastics. It can be produced by injection molding, extrusion, blow molding and other processing methods, and 100% of the nozzle corners are crushed and used directly for secondary use. It not only simplifies the processing process, but also reduces the processing cost. Therefore, the thermoplastic elastomer TPE/TPR material has become the latest material to replace the traditional rubber. Its environmental protection, non-toxicity, comfortable hand feel and exquisite appearance make the product more creative. Therefore, it is also a more user-friendly, high-grade new synthetic material, and it is also a world-wide standard environmental protection material.

The main use of thermoplastic elastomer

Thermoplastic elastomer is a new type of polymer material between rubber and resin. It can not only replace part of rubber, but also modify plastics. The dual properties and wide characteristics of rubber and plastic of thermoplastic elastomers make it widely used in the rubber industry to manufacture rubber shoes, rubber cloth and other daily products and hoses, tapes, rubber strips, rubber sheets, rubber parts and adhesives, etc. Various industrial supplies. At the same time, thermoplastic elastomers can also be used instead of rubber in the modification of general-purpose thermoplastic resins such as PVC, PE, PP, PS, and even engineering plastics such as PU, PA, and CA, giving the plastics industry a new situation.

The advantages of thermoplastic elastomers

(1) It can be processed by general thermoplastic molding machines, such as injection molding, extrusion molding, blow molding, compression molding, and transfer molding.

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

(3) It can be molded and vulcanized with an extruder, with fast extruding speed and short vulcanization time.

(4) The waste materials generated during the production process (escape burrs, extrusion of waste rubber) and the final waste products can be directly returned for reuse.

(5) The used TPE products can be reused after simple regeneration, reducing environmental pollution and expanding resource regeneration sources.

(6) There is no need for vulcanization, which saves energy. Take the energy consumption of high-pressure hose production as an example: rubber is 188MJ/kg, TPE is 144MJ/kg, which can save energy by more than 25%.

(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 and performance are easier to grasp.

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

Disadvantages of thermoplastic elastomers

The heat resistance of TPE is not as good as that of rubber, and its physical properties decrease greatly as the temperature rises, so the scope of application is limited. At the same time, the compression deformation, resilience, and durability are inferior to rubber, and the price is often higher than that of similar rubber. But in general, the advantages of TPE are still very prominent, while the shortcomings are constantly being improved. As a new type of energy-saving and environmentally friendly rubber raw material, the development prospects are very promising.
