SOFPRENE® TPE-S (TPS) - Superior Elasticity and Versatility

Celanese TPE-S Sofprene® T is a thermoplastic elastomer based on SBS (styrene-butadiene-styrene), suitable for injection moulding or extrusion. Sofprene® T TPS is also ideal for 2K moulding with PP (standard grades) and PS (special grades).

General Information: The elastic characteristics of thermoplastic elastomers like Sofprene® T are key properties. For TPE families, the most important general properties include:

• Hardness: Measured in Shore A or Shore D.
• Compression Set: Describes the elastic properties of Sofprene® T TPS. It measures the permanent deformation of the polymer under a specified load and temperature for a measured time. The lower the percentage value, the better Sofprene® T TPS resists permanent deformation and is thus more elastic.
• Density: Varies greatly grade by grade and significantly influences the final part price.
   

TPS (TPE-S) Sofprene® T Offers a Wide Range of Grades:

• Hardness range from 25 Shore A to 40 Shore D
• Low temperature limit down to -50°C
• Maximum continuous temperature up to 60°C
• High transparency grades
• Density range from 0.90 g/cm³ to 1.25 g/cm³
   

Main Sofprene® T TPS Properties:

• High elastic recovery at low and room temperatures
• Limited UV resistance
• Excellent colourability
• High thermal and electric insulation values
• Good abrasion resistance
• Specific rheology for each type of processing
