Paper/phenolic resin laminated plastic

(SRBP - Synthetic Resin Bonded Paper)

Good quality electrical insulation in moulded sections Swan Brand TUFNOL is a good quality electrical insulating grade, similar in performance to Kite Brand TUFNOL.  It is produced in solid moulded sections, such as rod, square bar, etc., to complement the Kite Brand range of sheet and hollow moulded sections (e.g. tube).

What is Swan Brand used for? This grade is used wherever a rod, bar or other solid moulded section of paper based laminate is required.  Items such as insulated end caps, turned spacers, mounting posts, electrode supports and insulated conveyor hanger posts often require a round rod section.  Also, Swan Brand rectangular moulded bar may be preferred for certain components, such as mounting blocks, where tapped holes are drilled in several different directions.
