As you know from other articles that, thermoplastics and elastomers are different subgroups of polymer materials. But there is a polymer material that is called as thermoplastic elastomers which has very different chemical properties. In here, we will explaim these chemical properties and applications that derives from these properties.
What Are The Properties And Applications Of Thermoplastic Elastomers?
Actually, they are thermoplastic materials but have elastomeric behaviors. In elastomer market, they have very important place. Thermoplastic elastomers does not take their elastomeric behavior from their cross-linked molecular structure, they take their elastomer characteristics from their chemical connections between different phases in that are exist. These phases are soft and hard phases that they constitutes the thermoplastic elastomer.
They have block copolymer of styrene-butadiene-styrene block copolymer which is a very characteristic for this group. Thermoplastic elastomers includes different two materials that are not chemically incompatible to each other. So they for different phases. So chemical bondings between these phases constitutes the thermoplastic elastomer materials.
General applications of thermoplastic elastomers are; automotive molded parts, extruded tubes, wire coating and footwear.
- Properties Of Styrene-Butadiene-Styrene: The symbol of this polymer in market is ‘SBS’. It hase very important place in elastomer market which has market share of 12%. Service temperature limit is between -50C and 60C. At higher temperatures, it shows thermoplastic properties. Elongation at failure of SBS is around 400% according to its original shape. Tensile strength is 14 MPa.
These are the general properties and characteristics of thermoplastic elastomers. Do not forget to leave your comments and questions about thermoplastic elastomers below. Your precious feedbacks are very important for us.
