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

Polymer Type

Thermoplastic

Advantages

Hard grade with accompanying abrasion resistance, higher tensile strength and flexural modulus compared with other SBS TPE grades (35A - 35D). Cheaper than 35A and 80 A. Good fatigue resistance.

Disadvantages

Inferior low temperature characteristics compared with other SBS TPE grades (35A - 35D).
