Work temperature

From 100ºC to 200ºC

Advantages

Resistance to corrosion
Molding diversity


ADVANTAGE

The mechanical and magnetic values will vary depending on the materials. These materials used in the injected magnets are mainly polyamides (PA6-PA11-PA12).

This type of injected magnets are more resistant to corrosion than sintered materials, for this reason they can be used in most applications without special coatings.

WORK TEMPERATURE

With this type of injection materials maximum temperatures of 100ºC of work are obtained for PA12 and approximately 120ºC for PA6. For working temperatures of 200 ° C, polyphenol is used, which allows good behavior at high temperatures. Epoxy resins that can be used up to temperatures of 120ºC.
