AT1600非石棉板材
This is comprised of non-asbestos fibre such as Kevlar and inorganic mineral fibre,machining with synthetic rubber.The asbestos are constrained in the environment-friendly industry,thus the non-asbestos product is the best alternative material.Application:water,steam,hot oil,lye,chemicals and hot atmosphere.

AT1700 Asbestos-Rubber sheet
Asbestos rubber sheet is usually cheap and easy to use.It is comprised by asbestos fibre,rubber,fillers and rubber additives.It can be used in water,steam,atmosphere,weak acid,strong alkali and neutral medium.User should particularly inform for strong acid medium use.Specifications for Asbestos rubber sheet are the same as Non-Asbestos sheet.The performances for Asbestos-Rubber Sheet are listed in Table 23:
