Olefinic Based Thermoplastic Elastomer - Ol TPE 65A

Polymer Type

Thermoplastic

Advantages

Exhibits both elastomeric performance of vulcanised rubber and processing simplicity of thermoplastics. Highest elongation at break and best low temperature impact resistance of the olefinic based TPE’s ( 65A  - 93A ).

Disadvantages

Lowest hardness, abrasion resistance, tensile strength and modulus of the olefinic based TPE's ( 65A  - 93A ).
