B9129 Composite Neoprene Rubber Faced Phenolic Cotton SRBF

Material Details

Grade: B9129. (Type: Composite / Specialist / Other Grades)
Description: Phenolic Cotton. Neoprene Rubber Faced SRBF
Comments: The B9 family of products are high performance composite sealing/insulating materials designed to meet specific needs, primarily in the Oil and Gas distribution industries. B9129 combines the sealing properties of Neoprene with the strength and insulation properties of a medium weave SRBF laminate.
Conventional materials can cause problems due to either with being too soft to withstand the compressive forces of the mating surfaces or too hard to form a satisfactory seal. The thickness of the sealing rubber face(s) on Attwater B9 laminates is kept to a minimum (typically 0.4mm). This combined with the high compressive strength of the core eliminate the compression effects normally associated with softer materials. This makes the product capable of withstanding compressive loads in excess of 30,000 psi.
The product also acts as electrical insulation between the mating surfaces reducing electrolytic effects, which can lead to corrosion.
The Attwater Group also manufactures a complementary range of insulating bushes and washers to enable complete insulated flange joints to be assembled.
Other grades of rubber are available on request.
