TPE Elastomers 2nd generation | ||||||||
The thermoplastic elastomers can be divided into: blends and block copolymers. Block copolymers are chains of molecules with various segments, which by cooling are organized into "hard" and "soft" segments. The 2nd generation thermoplastic elastomers are: TPE-S (Styrene block copolymer) TPE-U (Polyurethane thermoplastic) TPE-E also as TPC-ET (Thermoplastic polyester elastomer) TPE-A (Thermoplastic Polyester -Polyamide) TPE-O (Thermoplastic polyolefin elastomer) TPE-V (vulcanized thermoplastic polyolefin elastomer) The different types of TPE are differentiated by their properties. The TPC-ET are distinguished by good properties of mechanical and chemical resistance, the TPU by their values of resistance to abrasion; however, these two types have an optimization potential, especially in CS (Compression Set) at high temperatures. TPS is modifiable in different characteristics. However, uses in oil and at high temperatures are a challenge for these materials. TPAs stand out for their resilience but like TPUs they are not easy to process. Vulcanized thermoplastics (TPV) are a series of high-performance elastomers that combine the desirable characteristics of vulcanized rubber, such as flexibility and low compression, with the ease of processing thermoplastics. | ||||||||
TPC-ET | ||||||||
TPE-E thermoplastic polyester elastomers can be manufactured in various forms, from soft to rigid. By altering the plasticizer ratio (such as polyalkene glycol ether) you can get a Shore hardness range between D 25 and D 72. The useful temperature range of TPC-ET is between -60 ° and 125 ° C. It is frequently selected for the manufacture of cables due to its excellent performance under dynamic load. The high resistance of TPC ET to the bending load and its resistance to impact are also crucial factors in its favor. It is also resistant to chemicals, oils and solvents. | ||||||||
TPE-U | ||||||||
Thermoplastic polyurethane, also known as PUR or polyurethane rubber, is one of the best known thermoplastic elastomers. It is easy to process and has excellent mechanical and chemical properties. TPU has preference when we manufacture flexible cable assemblies. | ||||||||
TPE-O | ||||||||
The behavior of TPE-O under mechanical load can vary widely and can be modified to suit individual requirements. Although these polyolefin elastomers are less suitable for high temperature applications, their excellent electrical characteristics make them very attractive. | ||||||||
TPE-A | ||||||||
Polyamide thermoplastic elastomer is similar to TPE-E because it also has good mechanical and chemical properties, but has the additional advantage of greater resistance to acidic and basic environments. | ||||||||
TPE-S | ||||||||
TPE-S is very similar to polyolefin thermoplastic elastomers. In some cases, however, it provides an even greater elasticity when subjected to bending. | ||||||||
