Phenolic Paper laminate SRBP Material - Heron Brand

Phenolic Paper laminate

Paper/phenolic resin laminated plastic

(SRBP – Synthetic Resin Bonded Paper)

Heron Brand Tufnol is a first class electrical insulating material with very low moisture absorption. It is especially suitable for use in humid or tropical environments, where its electrical properties are retained to a high degree. It has excellent electric strength, very high insulation resistance after immersion in water and is designed to meet the highest electrical standard for phenolic paper materials in BS and IEC specifications. It machines well and can be hot punched in thicknesses up to 3.2mm.

What is Heron Brand used for?

Heron Brand is used in electrical applications where high insulation performance is required, with stable properties in a moist or humid environment. Items such as terminal boards, mounting plates, cover plates and insulating spacers have frequently been made. This grade has been largely superseded by the use of epoxy and other materials in such applications and is retained in our range for instances where it is needed for particular specification requirements.
