About us

Invul (injection and vulcanized elastomers) is a company specialized in the design and manufacture of molded silicone parts..

Invul was founded at the end of the 90's in Bilbao (Spain), with the name of Invultrans, as a study for the application of silicone rubber used as electrical insulation for the electrothecnical sector of medium and high voltage ; It was unknown in an industrial way in Spain, until that moment.

The application of silicone, as insulation component, offers an alternative to similar application materials (resins, porcelain, glass insulators) improving the insulation properties and durability. In order to expand their facilities, Invul moved its factory, in 2007, to the town of Guriezo in Cantabria (Spain), increasing its area from 500 m2 to 1500 m2.
