Kraiburg TPE has developed a series of PIN flame retardant TPE with adhesion to polyamide compounds. There is a strongly increasing demand for multi-material components, bringing together both engineering plastics (for mechanical performance), in particular polyamides, and TPE’s (thermoplastic elastomers) for functions such as sealing, vibration or sound damping, soft-touch or grip. Kraiburg’s new PIN FR TPE series combining fire performance with excellent adhesion, enabling combination in complex multi-component parts. Adhesion was shown to depend on the properties of the polyamide, the flame retardants and on the glass fibres. UL94-V0 @ 3 mm was achieved, with a TPE compound offering low melt temperature (190°C) for easier processing. Peeling resistance of 2.5 N/mm and above (VDI 2019) was shown. Applications include electrical engineering components such as connectors, relay components or switch boxes. Further flame retardant TPE series, for example with adhesion to polypropylene, are available in the portfolio of Kraiburg TPE. Kraiburg TPE GmbH & Co. KG is a leader in specialist and industrial TPEs.
