Ensoft® TPE-S consists of styrene-diene copolymers. The unsaturated butadiene styrene (SBS) copolymers are of the lower cost and performance members of this group whereas hydrogenated/saturated styrene-ethyl-butyl-styrene (SEBS) and styrene ethyl-ethyl-propyl-styrene (SEEPS) are the higher cost high performance members. Compounds of these copolymers incorporate suitable thermoplastics (such as PP, PE, PS), oil and fillers in a co-continuous phase morphology.
Ensoft® TPE-S offers:
- Hardness range from 5 Shore A to 60 Shore D (SBS 30 Shore A to 45 Shore D)
- Service Temperature: -50 to +110°C (dynamic; SBS -50°C to +70°C) -50 to +130°C (Static/Peak; SBS -50 to +110°C)
- Excellent ozone, UV and weather resistance due to saturated elastomeric phase; SBS has moderate UV, ozone and weathering resistance due to the presence of double bond
- Chemical resistance to many aggressive mediums
- Low compression set and good elasticity in a wide temperature range
- Adhesion to a broad range of polar and non-polar substrates such as PP, PA, ABS, PC, PS…
- Broad product range including soft touch, expandable, high temperature resistant, low compression set, halogen free FR and many other speciality grades
- Excellent colourability
- Good elasticity, tear strength compression set at low-med temp
