What material is TPR? What is the difference between TPR and TPE? At present, many people still confuse TPR with TPE. In fact, TPR and TPE are different in concept extension. TPE refers to thermoplastic elastomer, which is a general name for a large class of materials, including TPR. Then this article will give you a specific explanation of what material TPR is. What is the difference between TPR and TPE?
1. what material is TPR?
TPR, which means thermoplastic rubber, is called Thermo-plasticrubber in English. some users in Asia call the mixed elastomer materials based on styrene elastomers SEBS and SBS TPR. however, for the convenience of distinguishing, domestic TPE and TPR manufacturers call SEBS-based blending modified elastomer TPE and SBS-based blending modified elastomer TPR. this is different from that of some users in Asia.
TPR material is a kind of thermoplastic soft rubber which has rubber elasticity and can be directly processed and molded without vulcanization. It has the resilience and good wear resistance of common rubber, excellent anti-skid and shock absorption performance, but its softness and comfort are superior to rubber. In addition, TPR materials are inferior to vulcanized rubber in tensile strength, fatigue resistance and mechanical properties.
In addition, the price of TPR materials ranges from 12,000 yuan to 35,000 yuan/kg, and the price will be higher if there are special requirements, such as food grade, flame retardant grade and high temperature resistance grade. Therefore, when the customer asks the supplier for the price, the supplier will generally ask the customer what products to make, what physical properties and environmental protection requirements are required, and the user can provide the sample or physical properties table and environmental protection standards, so that the supplier can make targeted quotations.
Second, what is the difference between TPR and TPE?
1. the substrates of TPE and TPR are different. TPE is based on SEBS and TPR is based on SBS.
2. Production technology: TPE processing temperature is slightly higher than TPR.
3. Different weatherability: TPE has better weatherability and TPR is relatively poor, which is why many high-end products in the market are made of TPE materials instead of TPR.
4. Appearance: TPR bright surface, TPE foggy surface, and good hand feeling.
5. The application range of TPR is narrower than that of TPE.
Because TPR material meets the environmental protection testing standard, it can replace PVC material, and is used as the first choice of raw materials in many industries such as adult products, medical treatment, automobile, electronic communication, etc., and it produces products such as sex toys, medical equipment (medicine stoppers, medical catheters), industrial appliance handles, various handles, luggage cart casters, sports equipment (tension belts, yoga mats, etc.), which are widely used.
