IntroductionIntroduction andand PurposePurpose
Information and practical tips aboutThermoplastic Elastomers and processing guide.
Smart processing and smart choiceof polimeric compounds is possible with ; Understanding the raw material. Good analysis of the process Design of the final product

What is TPE?Thermoplastic Elastomers(TPEs) are the products which contains plastic
and elastromeric properties. TPEs are fast and economic proccesible materials as plastics, beside of their plastic behiavour advantages, TPEs contain also common-known properties of rubber such as physical and performanse behaviours.
