Plastic welding rods TPO - Thermoplastic elastomers based on olefin
TPO (thermoplastic elastomers based on olefin) are materials that consist of a soft elastomer and a hard thermoplastic component. TPO is soft and can be plastically deformed when heat is applied, which enables processing by plastic welding, injection molding and extrusion. Thermoplastic copolyester elastomers have a wide range of uses, for example in bumpers, body seals, components, handles, hoses and seals.
Thermoplastic elastomers are plastics in which elastic polymer chains are bound into thermoplastic material. Copolymers are used either as random or as block copolymers. The former consist of a crystallizing main polymer such as B. polyethylene, the degree of crystallization by a randomly installed along the chain comonomer such. B. vinyl acetate is reduced to such an extent that the hard phase in the finished material no longer has direct contact. As in conventional elastomers, they then act as isolated cross-linking points. TPO is difficult to paint, print and stick on. The melting point of thermoplastic copolyester elastomers is approx. 200°C, the long-term use temperature is max. 100°C.
