Styrene-Butadiene-Styrene Based Thermoplastic Elastomer - SBS TPE 35A.

Polymer Type

Thermoplastic

Advantages

Higher elongation at break and better low temperature performance compared to other SBS grades (35A - 35D).

Disadvantages

Lower hardness, abrasion resistance, tensile strength and modulus compared to other SBS TPE grades (35A – 35D).
