KEBAFLEX H / SPBT 60 A.01 natural
TPE-S, Shore A70, modified for adhesion to PBT and polyester elastomer, also for extrusion applications
TPE-S - KEBAFLEX / S
Under the trade name KEBAFLEX / S we market a range of thermoplastic elastomer compounds based on SEBS/PP. KEBAFLEX / S is available in various Shore hardnesses from below A10 to above D50 and is often used as a substitute for rubber due to its cost-effective processing by injection molding. It is soft and flexible, freely colorable, shows good elastic behavior up to 100°C and offers a pleasant feel. A wide range of modified compounds is available, e.g. adhesion-modified grades for 2K injection molding, printable grades, grades with optimized compression set, etc.
Typical areas of application
- Sealing elements
- Haptic components
- Cables and connectors for media-carrying systems
- Electrical and electronics industry
- Household appliances
- Mechanical Engineering
- Furniture industry
- Sports & Recreation
- good haptics
- adhesion modified

General processing instructions:
The relatively high viscosity requires high injection speeds and medium injection pressure. To avoid high internal stresses, and to improve 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.
A compound temperature at the upper limit also improves adhesion.
Very good venting of the cavity is a basic prerequisite for achieving a high injection speed and, consequently, good adhesion and good surface quality.
The selected barrel capacity should not exceed 5 – 6 shots to avoid thermal material damage.
The melt should be sheared sufficiently, for this purpose the use of melt screens can be useful. This improves homogeneity and positively influences the surface quality of the extrudate.
