Tufnol SRBP Material - Rolled Laminated Paper Tubes
Phenolic Paper laminate
Paper/phenolic resin rolled laminated plastic tubes
(SRBP – Synthetic Resin Bonded Paper)
The Tufnol range of rolled laminated paper tubes have been developed to complement the range of moulded tubes. RL tubes have good mechanical strength, low water absorption and are resistant to weathering and to chemical attack by mild acids and alkalis. They are used where electrical insulation is required and in many instances where the requirement is simply for a low cost, strong and rigid non-metallic tube.
Three grades are available:
- Grade RL P/1 – A low cost commercial quality grade, suitable for low voltage electrical applications and some mechanical uses.
- Grade RL P/2 – A good electrical insulator with good dielectric properties. Made to BS EN 61212 Type PF CP 23.
- Grade RL P/3 – Superior mechanical properties to Grade RL P/1, particularly with regard to its higher bursting strength. Machines well.
Application
- In general, Grade RL P/2 is used primarily for electrical insulation components such as bobbins, coil formers, insulating spacers and sleeving. The other grades are used for low voltage insulation and for low cost mechanical applications, such as handles on welding guns, structural components and containers for pyrotechnics, and similar items.
