Characteristics of thermoplastic elastomer materials
1. can be processed by general thermoplastic molding machine without special processing equipment.
2. The production efficiency is greatly improved. It can be vulcanized directly by rubber injection molding machine, and the time is shortened from about 20min minutes to less than 1 minute; Because the required vulcanization time is very short, it can be vulcanized directly by extruder, and the production efficiency is greatly improved.
3. It is easy to recycle and reduce the cost. Wastes (burrs, rubber extrusion) and final wastes generated in the production process can be directly returned for reuse; Used TPE products can be recycled after simple regeneration, which reduces environmental pollution and expands the source of renewable resources.
4. Save energy. Most thermoplastic elastomers do not need vulcanization or the vulcanization time is very short, which can effectively save energy. Take the energy consumption of high-pressure hose production as an example: rubber is 188MJ/kg, and TPE is 144MJ/kg, which can save energy by more than 25%.
5. The application field is wider. Because TPE has the advantages of both rubber and plastic, it has opened up a new application field for rubber industry.
6. It can be used to strengthen and toughen plastics. The self-reinforcing property is great, the formula is simplified, the influence of the compounding agent on the polymer is less, and the quality and performance are easier to master. However, the heat resistance of TPE is not as good as that of rubber. With the increase of temperature, the physical properties are greatly reduced, and the application scope is limited. At the same time, the compression deformation, elastic recovery and durability are worse than those of the same rubber, and the price is often higher than that of similar rubber. Nevertheless, the advantages of TPE are still outstanding, and various new TPE products are continuously developed. As a new rubber raw material with energy saving and environmental protection, its development prospect is very promising.
Advantages of TPE material:
1. Easy processing, no need for vulcanization, greatly improved production efficiency and short molding cycle.
2. 100% recycling, reducing the cost, is an ideal material to replace rubber and silica gel.
3. The performance is relatively stable, with good temperature resistance (service temperature range -50- 100℃), aging resistance, chemical resistance and solvent resistance.
4.TPE materials do not introduce heavy metals or add toxic phthalate plasticizers in the production process, and meet the environmental protection tests such as ROHS, REACH, EN7 1, PAHS and FDA. It is the best material to replace PVC.
5. Save energy. Most thermoplastic elastomers do not need vulcanization or the vulcanization time is very short, which can effectively save energy.
Conclusion: Through Bian Xiao's introduction above, I believe everyone is interested in T? Have a certain understanding of the characteristics and advantages of pe materials. Tpe material is a very high-quality thermoplastic material. Toys and sports equipment made of tpe materials not only look very beautiful and elegant, but also have strong practicability, extensibility and elasticity. Bian Xiao suggested that you choose some tpe materials of big brands, because the quality of tpe materials of big brands is relatively reliable. I hope that the above introduction can help you understand the characteristics and advantages of ppt materials.
