Norseal silicone rubber, foam and SNS tapes for high‑performance sealing in NZ

Saint‑Gobain Norseal performance insulation and gasket materials provide long‑term sealing, cushioning and vibration control in demanding industrial, transport and electronics environments across New Zealand. Brown International supplies Norseal silicone sponge, silicone foam, solid silicone rubber and Norseal SNS adhesive tapes locally, backed by technical advice on grade selection, compliance and format.

What is Norseal and where is it used?

Norseal is Saint‑Gobain’s family of silicone rubber and foam products engineered for reliable gasketing, insulation and environmental sealing under temperature, weathering and vibration that quickly break down conventional elastomers. Typical Norseal applications include enclosure gaskets, access panel seals, transport and mass‑transit components, outdoor electrical cabinets, lighting, medical equipment interfaces and vibration‑damping pads in industrial machinery.

Key benefits of Norseal for gaskets and insulation

Norseal silicone rubber and foam products deliver excellent compression set resistance so gaskets maintain load and sealing performance after repeated cycling, reducing the need for frequent change‑outs. Many grades are recognised for flame retardance and low smoke and toxicity, meeting important standards such as UL 94 V‑0, FAR 25.853, NFPA 130 and UL 50E for electrical enclosures and mass‑transit uses.

Norseal silicone foam and sponge

Norseal silicone foam and sponge materials provide conformable, lightweight gasketing and insulation where compression recovery, fire performance and environmental sealing are critical. Low‑density foams such as Norseal F‑12 suit light gasketing and insulation, while medium‑density closed‑cell foams like Norseal F‑20 are designed for transportation and mass‑transit applications with higher mechanical demands.

Norseal solid silicone rubber

Norseal solid silicone rubber is specified where superior durability, dimensional stability and resistance to extreme temperatures and harsh environments are required. Reinforced grades with fibreglass offer additional strength for high‑pressure gaskets, press pads, conveyor belts and expansion joints, all while maintaining thermal stability over a wide temperature range and low compression set.

Norseal Silicone SNS tapes for gasketing and damping

Norseal Silicone SNS tapes, including Norseal 200A SNS, combine a compressible silicone sponge core with an aggressive acrylic pressure‑sensitive adhesive for demanding gasketing, sealing, cushioning and vibration‑damping applications. These tapes offer strong, flexible and weather‑resistant performance for environmental gaskets, vibration damping and thermal insulation, noise reduction, clamping of hot parts and reducing electrolysis between dissimilar metals in industrial, aerospace and electronics equipment.
