December 30,2017 to stay at work, in the face of the end of 2017, the heart is full of all kinds of ups and downs, this year has grown a lot, bear a lot, then still can not block me to share TPETPR material performance and related information So today we are going to talk about the difference between TPE and EPDM. TPE is one of the most widely used materials in our life. What is the difference in performance between TPE and EPDM. What are the differences between the properties of TPE and EPDM First, Thermoplastic elastomer TPE generally called TPE material, basically belong to the Thermoplastic elastomer. STYRENIC TPE, also known as TPS, is a block copolymer of Butadiene or Isoprene and Styrenes with properties similar to those of SBR rubber. Advantages: High Elasticity of rubber, and it can be processed by injection molding; environment-friendly, non-toxic, safe, excellent colorability, soft touch, weather resistance, fatigue resistance and temperature resistance, superior processability, no vulcanization, can be recycled to reduce costs, can Be injection molding, and PP, PE, PC, PS, ABS and other Matrix material coating adhesion, can also be formed separately. DISADVANTAGES: SBS AND SIS is the biggest problem of poor heat resistance, the use of temperature can not exceed 80 °C. At the same time, its strength and elongation, weather resistance, oil resistance, wear resistance and so can not be compared with rubber. Second, processing technology comparison Thermoplastic elastomer has good processing properties, can be extruded, injection molding, blow molding processing into various products, but EPDM processing method is relatively simple to a lot. For example, TPE and EPDM have different processing technology: 1. THERMOPLASTIC ELASTOMER TPE: Plastic extruder rising to the set temperature → feeding extrusion → cooling trough shaping → drawing and cutting → complete operation 1 ~ 2 people, Short Cycle, low energy consumption. 2. EPDM: Rubber cutting machine → batch weighing → mixing machine coarse mixing → mixing machine fine mixture with vulcanizing agent and vulcanizing agent → leaving the tablets for general 24 hours → re-cutting strips → cooling → putting them into extruder extrusion → entering the microwave vulcanizing section and hot air constant temperature box vulcanization → traction surface breaking → input of finished processing equipment THERMOPLASTIC ELASTOMER TPE equipment investment is low, can be processed with ordinary plastic processing equipment, processing costs are low. Thermoplastic elastomer TPE EPDM ordinary four-stage heating extrusion machine, open mixer, raw rubber cutting extrusion products, cooling water trough rubber extruder, indexing machine hot air thermostat, traction injection products ordinary plastic injection molding confidential mixer, open mixer, raw rubber cutting machine, rubber injection press expensive Thermoplastic ELASTOMER TPE has the same good elasticity and texture as EPDM There are many common characteristics between TPE AND EPDM: Excellent rubber properties, excellent weather resistance, bromine oxygen resistance, UV resistance, excellent sealing water resistance, due to the excellent processing properties of TPE and EPDM and there are many different. More on TPE raw material information please continue to pay attention to us, we will share a variety of TPE raw material performance information to you!
