Norseal F-12 and F-20 silicone foam rubber provide excellent flame retardance (UL 94 V-0) with low toxicity and smoke generation in a conformable expanded cellular material.
Norseal F-12 has a modified cell structure and is produced in a low density for light gasketing and insulation applications.
Norseal F-20 has a finer cell structure (closed cell) and produced in a medium density for Mass Transit and Transportation applications.
Available thicknesses range from 1/32” (0.8mm) to 1” (25.4mm). The standard colour is grey for both F-12 and F-20, but other options like white and black are available, with minimum quantity requirements.

Reinforced Solid Rubber
Norseal silicone rubber reinforced with fiberglass increases the product’s dimensional stability for high-pressure applications, while functioning over a wide temperature range. Most products feature different solid silicone rubber durometers (hardness) on both sides of the fiberglass reinforcement. We also offer a product with a closed cell silicone sponge on both sides of the fiberglass substrate. Materials can be supplied in yard goods and sheets, with and without pressure-sensitive adhesive on one side.Thicknesses range from .032” (.81mm) up to .125” (3.17mm). Products are designed for various ranges of pressure and temperature resistance.
Press pads for PCB laminations
The Norseal silicone solid rubber line includes specification grade, high-performance grade and electrically conductive grade products. Products range in thicknesses from .012” (.031mm) to .500” (12.7mm) in durometer, hardness from 30-70 on the Shore A scale. Materials are provided in both flat sheet stock size 36”x36” (914mm x 914mm) and flat yard goods in 36” (914mm) continuous length rolls. Temperature ratings generally range between -100°F to + 500°F (-73°C to + 260°C).
Often referred to as red rubber because the earliest offerings were all red in color, Norseal silicone solid rubber also comes in clear, grey, black and green, with minimum quantity restrictions. Many Norseal silicone solid materials meet the most popular solid rubber specifications, including ZZR-765 and A-A-59588 (ZZR-765 is now a listing within A-A-59588).
Release material for packaging and composite moulding
The Norseal full line of closed cell expanded silicone sponge rubber for a variety of gasketing, cushioning, insulating and protective applications, over a wide temperature and environmental range. Our experts can help you choose the proper product for your requirements, including formulations designed for general gasketing, flame retardant cushions, specification grade, solvent resistant gaskets and weather seals.
Key benefits of our closed cell sponge include thermal stability over a wide temperature range, excellent compression set resistance, ozone and UV resistance. Saint-Gobain subjects all of our closed cell sponge products to a special final cleaning process that lowers the material out gassing for cleaner operation.
