Attwater Group
Glass Based Laminates (SRBG)
Bakelaque technical laminates are manufactured to exacting quality standards using modern high pressure laminating techniques, which ensure consistently high quality and performance. Traditionally known for outstanding electrical insulating properties, glass reinforced sheets also have high mechanical strength, high rigidity and excellent chemical resistance. The sheets are relatively lightweight with a density of between 1.8 and 2.0, and can be machined into complex shapes to close tolerances. The thermosetting resins used to manufacture glass reinforced laminates perform well at elevated temperatures and exhibit low coefficients of
thermal expansion. Selected resins and specially treated grades of woven glass cloth are employed in the production of these high performance materials. High electrical strength, low moisture absorption, good dimensional stability and excellent mechanical strength are their main attributes.
Fabric Based Laminates (SRBF)
Bakelaque technical laminates are manufactured to exacting quality standards using modern high pressure laminating techniques, which ensure consistently high quality and performance. Traditionally known for outstanding electrical insulating properties, Bakelaque sheets also have high mechanical strength and excellent chemical resistance. The sheets are relatively lightweight and can be readily machined into complex shapes to close tolerances. The thermosetting resins used to manufacture Bakelaque laminates perform well at elevated temperatures and exhibit low coefficients of thermal expansion.
The fabric used in the manufacture of the Attwater range of SRBF laminate is woven from 100% cotton yarn and is of high quality. The weave varies from 40 threads per cm (very fine weave) to 16 threads per cm. The finer weave grades such as B10 and B10S exhibit improved surface finish, good electrical and physical strength and excellent machining characteristics. All grades have better load bearing characteristics than SRBP types and are used in a wide range of mechanical applications. Phenolic Cotton grades are golden brown, which darkens with age to mid brown.
