BISCO® HT800-HT840 Flame Retardant Silicone Sponge sheet

Product Codes: BISCO HT-800SH, BISCO HT-820SH, BISCO HT-840SH

Product Description

BISCO® HT800-840 are medium to extra-firm grades of silicone sponge. They are highly versatile and suitable for sealing and protecting communication, electronics and lighting enclosures in outdoor environments. These materials have excellent memory and low stress relaxation which reduces maintenance costs associated with gasket failure caused by compression set and material softening. The compact cell structure of BISCO® HT-800 – HT-840 grades provide exceptional sealing performance against penetration from wind-driven rain, fire and fine particles. They also offer exceptional vibration isolation and shock reduction in transportation vehicles and electronic components.
