Thermoplastic Elastomers (TPE) are well known for their ability to be stretched repeatedly and still return to their approximate original size. Thermoplastics are generally low modulus, flexible and can usually be recycled.
Some applications are using thermoplastic elastomers as an alternative to traditional thermoset rubber materials, such as EPDM, SBR and NBR.rubbers. TPEs are also being used to improve impact strength of rigid thermoplastic materials.
Difference Between Thermoplastic and Thermoset Materials
Thermoplastic Elastomers are different from thermoset elastomers in that they become soft when heated and harden when cooled. This process can repeat itself many times. Thermoset Elastomers, on the other hand, undergo a chemical change during processing, becoming cross-linked and permanently fused.
THERMOPLASTIC VULCANIZATE | TPV
Thermoplastic vulcanizates are part of the thermoplastic elastomer family of polymers but differ because the rubber component is “vulcanized” or crosslinked, which creates favorable properties such as good compression set and heat resistance. Thermoplastic vulcanizates are processed like plastic but have the properties and performance capabilities of rubber.
TPV is closely related to EPDM in terms of performance, but also compare closely to other elastomers and can be a cost-effective, performance-enhancing alternative for another traditional rubber material.
– Good compression set
– Wide array of hardness options
– Excellent resistance to acids
– Oil, ozone, UV and flex fatigue resistant
– Excellent low-temperature performance
– Great Cost-saving alternative
– Custom Compounding: Can increase properties
Several industries turn to TPVs for their products, most prominently the automotive, HVAC, appliance, construction, industrial and sealing. Thermoplastic Vulcanizates are a fantastic alternative with great processing at an excellent price. TPVs can also be color-matched, providing additional opportunities for product creation and solutions. This innovative material is suitable for all industries, be sure to talk to your support team to see if TPV is a good material for you.
