HT840 Flame Retardant Silicone Sponge Sheet
From £111.03 Exc VAT
HT840 flame-retardant silicone sponge sheeting (extra-firm density). This grade offers excellent sealing and durability with a higher tear and tensile strength than lighter grades.
Its memory and low-stress relaxation makes it an excellent gasketing material. Furthermore, its resistance to UV, ozone and extreme temperatures makes it ideal for use in all environments. HT840’s cell structure prevents penetration from fine particles and rain.
Please note: This sheet is supplied in 915mm Wide
This material is suitable for press pads requiring greater conformability and even-pressure distribution at high temperatures. Other applications include, but are not limited to gaskets, anti-vibration/cushioning, HVAC systems, anti-fogging seals and battery pads/cushions in the automotive industry.
This sheeting is 915mm wide and sold by the metre.
