Pawtucket, R.I. — Teknor Apex Co. has introduced a new series of thermoplastic elastomers for overmolding on plastic substrates that meet requirements for medical devices.
Medalist MD-30000 series medical TPEs bond effectively to polycarbonate, ABS, PC/ABS, CoPe, PET, PBT, ASA, SAN, PMMA, POM, nylon and polystyrene. Each compound in the series is chemically modified for adhesion to specific substrates. They can be processed with multi-shot or insert molding and are applicable for wearable devices, soft touch grips for medical device housings, handheld devices, seals and gaskets.
The new series includes grades with enhanced softness, translucence, low compression set for effective sealing properties and resistance to lotions and other chemicals encountered by wearable devices.
Three of the Medalist MD-30000 Series compounds were introduced earlier this year after successful completion of a joint project with Covestro LLC, in which the materials were overmolded onto medical grades of polycarbonate and PC alloys and tested for adhesion, processability, and chemical resistance.
The TPE series are available worldwide.
Teknor Apex also has developed an online resource for over-molding TPEs, which can be accessed at www.teknorapex.com/overmolding-academy. It contains basic information about over-molding and adhesion, guides to process and material selection, and case studies.
