Materiales

Disponemos de una amplia gama de materiales y dedicamos importantes recursos a desarrollar nuevos materiales y a certificarlos bajo normativas de automóvil, Gas, Agua y otras aplicaciones.

Para las aplicaciones en contacto con agua potable contamos con certificaciones como WRAS, ACS, KIWA, W 270, NSF, ...
Para las aplicaciones en Gas contamos con certificaciones para los distintos rangos de temperatura de la EN 549 así como materiales certificados bajo UL 157, ...

Sabemos que en muchos casos, el correcto funcionamiento del sistema donde va montado nuestro producto depende en gran medida de las prestaciones del material utilizado y por esto somos muy sensibles a la hora de desarrollar los materiales y en asegurar los procesos de fabricación para que el material alcance sus propiedades óptimas.
