Ensoft® TPE-S - Thermoplastic Elastomers

Versatile and High-Performance Elastomers

Produced by Ravago, Ensoft® TPE-S is part of a wide range of thermoplastic elastomer grades, including TPE-S, TPE-V, and TPE-O. These elastomers are manufactured at Ravago’s factories in Turkey and Germany under the brand names Enflex®, Ensoft®, and Sconablend®.

Thermoplastic elastomers (TPEs) are a unique class of materials that combine the key processing and recycling properties of thermoplastics with many of the physical properties of thermoset rubbers, such as elasticity, low compression set, and high flexibility.

Ensoft® TPE-S: Ensoft® TPE-S consists of styrene-diene copolymers. The unsaturated butadiene styrene (SBS) copolymers are 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.

Key Features of Ensoft® TPE-S:

• 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 specialty grades

• Ease of processing (no pre-drying is required) and recyclability

Ensoft® TPE-S is suitable for various applications and processing methods such as blown and cast films, extrusion coatings, and lamination. These elastomers offer a versatile solution for industries requiring high-performance materials with excellent processing characteristics.
