Outside electronics and telecommunication products, if high sealing demands, mostly choose silicone rubber housing sheet + backed adhesive 3M tape for better sealing. IP grade (Ingress Protection) is well known as sealing protection grade.
Some silicone rubber housing washer for electric products is made of anti-fire rubber materials, like silicone, EPDM materials etc, and some auto products need NBR, HNBR materials etc for anti-oil function.
