Brand information

SOFPRENE® TPE-S (TPS)

Celanese TPE-S Sofprene® Tis a thermoplastic elastomer based on SBS (styrene-butadiene-styrene) that can be processed either by injection molding or extrusion. Sofprene® T TPS is also suitable for 2K molding with PP (standard grades) and PS (special grades).

General info:
The Elastic characteristics of a thermoplastic elastomers like Sofprene® T tend to be reported as a key properties (unlike standard plastics). Therefore for the TPE families the most important general properties tend to be:

• Hardness : measured in Shore A or Shore D.
• Compression set : A value describing the elastic properties Sofprene® T TPS . Compression set 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 thus 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
• With low temperature limit down to -50°C
• With max continuous temperature up to 60°C
• High transparency grades
• Density range from 0,90 g/cm3 up to 1,25 g/cm3

MAIN SOFPRENE® T TPS PROPERTIES ARE:

• High elastic recovery within at low as well as room temperature
• Limited UV resistance
• Excellent colorability
• High thermal and electric insulation values
• Good abrasion resistance
• Specific rheology for each type of processing
