1P/13 Tufnol
1P/13 Tufnol is an electrical insulating material where electrical requirements are moderate. 1P/13 Tufnol has higher mechanical strength than other grades in this range and greater impact strength. 1P/13 Tufnol is easy to machine and can be hot punched up to 3.2mm thick. Applications:
A wide range of electrical insulation applications at low voltage. It can also be used for applications with less demanding mechanical duties.
