The disadvantages of tpes in comparison to conventional rubber materials include.
Thermoplastic rubber melting point.
Thermoplastic polyurethane tpu is a melt processable thermoplastic elastomer with high durability and flexibility.
Tpu provides a large number of physical and chemical property combinations for the most demanding applications such as automotive wires and cables breathable films for leisure sports and textile coatings weatherable non yellowing films etc.
A thermoplastic is a plastic polymer material and is commonly fossil based.
These elastomers combine the performance benefits of rubber with the easy processability of thermoplastics but are more versatile than either material.
Tpv is a dynamically vulcanized alloy consisting mostly of fully cured epdm rubber particles encapsulated in a polypropylene pp.
Thermoplastic elastomers tpe sometimes referred to as thermoplastic rubbers are a class of copolymers or a physical mix of polymers usually a plastic and a rubber which consist of materials with both thermoplastic and elastomeric properties.
The formal definition of a thermoplastic rubber or elastomer tpe is a polymer blend or compound which above its melt temperature exhibits a thermoplastic character that enables it to be shaped into a fabricated article and which within it s design temperature range possesses elastomeric behaviour without cross linking during fabrication.
Thermoplastic vulcanizates tpv are part of the thermoplastic elastomer tpe family of polymers but are closest in elastomeric properties to epdm thermoset rubber combining the characteristics of vulcanized rubber with the processing properties of thermoplastics.
A further option is to combine with the curable rubber monomers and oligomers which can be polymerized under the same conditions where the rubber vulcanization is performed.
Thermoplastic elastomers tpe sometimes referred to as thermoplastic rubbers tpr are either blends of two or more polymers or special types of block copolymers.
Manufacturers shape and fabricate tpe when temperatures reach their melting point.
A thermoset rubber would be probably suitable for a brief exposure to that temperature.
While most elastomers are thermosets thermoplastics are in contrast relatively easy to use in manufacturing for example by injection molding.
Bio based tpe solutions derived from sources such as corn sugar cane beet soya beans cellulose or vegetable oil or plants or algae are being introduced.
Melting at elevated temperatures.
Tpr performs similarly to vulcanized rubber and is reusable and recyclable.
It is lightweight and has good abrasion resistance good tear strength weather resistance and electrical properties.
