Medical & Healthcare TPEs’ Adhesion & Processing Characteristic
TPEs bond easily when processed either through overmolding or co-extrusion with most commonly used structural plastics, eliminating the need for additional adhesives and allowing for faster and more cost-effective processing.
One of the main areas of growth for TPEs is overmolding. Many product designers are utilizing TPEs to add a “soft touch” to a rigid material. KRAIBURG TPE, a global TPE manufacturer of a wide range of TPE products and custom solutions for multiple industries, offers the THERMOLAST H series HC/AP, developed specifically for healthcare and medical device applications in the Asia Pacific. The HC/AP series compounds have a hardness range of 30-90 Shore A and can be used in a variety of applications due to their wide range of hardness from soft to semi-rigid.
Especially for medical and healthcare applications, KRAIBURG TPE’s HC/AP series of TPE compounds can be over-molded to produce comfortable, non-slip, and abrasion-resistant handles, grips, and buttons.
Through multi-component injection molding and extrusion, the THERMOLAST H HC/AP series has good bonding with polypropylene (PP) and polyethylene (PE) resins, allowing for flexibility in product designs.
As such, the compounds can be over-molded to alter the surface feel, improve aesthetics, and cushion against vibrations.
All-round material solutions
Good haptics, soft-touch properties, and elasticity improve function and design, allowing medical device manufacturers to be more creative with their product applications.
KRAIBURG TPE’s HC/AP compounds have a good compression set and are thus fitting for sealing and closure applications.
Furthermore, the compounds can be sterilized in an autoclave at 121°C or with ETO (gas); and have good thermoplastics processing and flowability, stretching the possibility for more medical part designs.
The HC/AP series compounds are safe for use in medical applications and meet standards such as cytotoxicity ISO 10993-5, GB/T 16886.5, biocompatibility testing according to ISO 10993-5 and GB/T 16886.5, as well as a number of international food contact and medical standards.
Other properties such as good chemical resistance, good sealing, and no cytotoxic potential, as well as the ability to be colored into various chromatic effects, present KRAIBURG TPE’s HC/AP compounds as all-round material solutions for the medical and healthcare segments.
