| Description: | Phenolic Paper. Neoprene Rubber Faced SRBP |
| 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. The products incorporate an SRBP or SRBF core with a chemically bonded Neoprene surface. 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 acts as electrical insulation between the mating surfaces reducing electrolytic effects, which can lead to corrosion. Attwater also manufactures a complementary range of insulating bushes and washers to enable complete insulated flange joints to be assembled. |
