TPE-S, Shore A25, natural



Unter dem Handelsnamen KEBAFLEX / S vertreiben wir ein Sortiment an thermoplastischen Elastomer-Compounds auf Basis SEBS/PP. KEBAFLEX / S ist in verschiedenen Shore-Härten von unter A10 bis über D50 verfügbar und wird wegen der kostengünstigen Verarbeitung im Spritzgussverfahren gerne als Ersatz für Gummi eingesetzt. Es ist weich und flexibel, frei einfärbbar, zeigt ein gutes elastisches Verhalten bis 100°C und bietet eine angenehme Haptik. Es steht ein breites Sortiment an modifzierten Compounds zur Verfügung, z.B. haftungsmodifzierte Typen für 2K-Spritzguss, bedruckbare Typen, Varianten mit optimiertem Druckverformungsrest, usw.

Pre-drying Recommendation:

May be required to remove surface moisture:
Dryer type: dry air dryer
Temperature: 80°C
Drying time: 2 – 4 h
Residual moisture: <0.02

Temperature recommendation:

Melt temperature: 220 – 250°C
Tool temperature: 20 – 40 °C

General processing instructions:

Due to the pronounced structural viscosity of KEBAFLEX / SG 25 A.1, high injection speeds and short injection times should be aimed for. Very good venting of the cavity is a basic requirement for achieving high injection speeds and good surface quality.

The relatively high viscosity requires high injection speeds and medium injection pressure. To avoid high internal stresses and to improve the 2K adhesion, the holding pressure should be kept as low as possible and the holding times of injection pressure and holding pressure should be as short as possible.
