 The polyphenylene ether compounds (PPE) VESTORAN® are amorphous materials with high heat deflection temperature.
VESTORAN® compounds and the parts produced from them have the following properties:
- very low water absorption
- hot water-resistant
- resistant to alkalis and acids
- very low mold shrinkage
- very low tendency to warp
VESTORAN® has proved to be highly suitable for production of coil bodies for vehicle electricity on account of its high dimensional stability, heat deflection temperature, dielectric strength, and ability to bond well to insulating compounds (epoxy resins). In addition, its low water absorption makes it a good choice for producing impellers for water pumps, for example, in engine cooling, but also for applications in machinery and engineering. Further applications include relay sockets, distributor cabinets, and large capacitor cases.
Plastic-Rubber Composites (K&K)
Most types of VESTORAN® are highly suitable for producing parts by means of the plastic-rubber process (K&K process), a particularly economical process patented by Evonik Degussa and Daicel-Evonik for producing thermoplast-elastomer composite materials. In contrast to conventional hard-soft composites, K&K composites dispense with adhesion promoters. Special compounds of the VESTORAN®, VESTAMID® D, and PA 6-3-T-based TROGAMID® blends series create strong and durable bonds between materials and rubber compounds, without the need for special pretreatment.
Applications of K&K composites with VESTORAN® include, for example, vibration dampers, seals and switch diaphragms.
Detailed information on the K&K process and suitable compounds is also provided in this brochure.
