HT-6210 and HT-6220 are low
durometer solid silicones formulated to be a
transition between a firm silicone sponge and
traditional medium hardness Shore A
durometer material. The unique product
softness is designed into the produc t enabling
the material to solve sealing and design issues
within various industrial markets. BISCO HT-
6210 and HT-6220 are available in various
thicknesses and manufactured in roll form to
allow fabricators to easily convert the material
to the proper dimensions.
Features and Benefits
Soft and compressible for superior sealing
performance
Flexible, yet durable enough to perform
under stringent conditions
Tight thickness tolerances for greater
reliability
Wide temperature range means the
material will work in harsh environments
Applications
Underwater lighting gaskets
Digital camera lens gasket
Battery hatch seals
