Bakelite
Bakelite (phenolic) is recognized as a world-wide material. The applications are innumerable because of the wide variety of the assortment. Bakelite, an optimal construction material, is also a material that is easily machinable in accordance with customers' drawings.
 | Bakelite skeets are manufactured in three grades that are Etronit, Etronax G-tronax. Sheets can be supplied in various sizes up to 1250 x 2750 mm. and in thickness from 0.2 mm. to 150 mm. | |||||||||||||
