Asbestos
Rubber Sheet/Oil-proof Asbestos Sheet
Item No.:ZD-GS1300/ZD-GS1310
Description:Asbestos
rubber sheet (asbestos joint sheet) is made of excellent asbestos,
rubber and other chemical materials.It is formed by rolling after
special mix-ture treatment .The thickness of asbestos rubber sheet not
larger than 0.5 to 5.0mm can be supplied.It is mainly for such media as
water and vapor.It is applicable to sealing and heat-insulation.Asbestos
rubber sheet is also used in the industries as machinery, automobiles,
farm, machinery and petroleum.Asbestos rubber sheet can be reinforced
with tin steel, copper, SS304 etc. wire mesh insertion.
