Rubber Lining

: http://mining-spare-parts.com/2-1-rubber-lining.html

The raw materials are imported, such as butyl rubber (USA EXXON MOBIL 1066, Japan JSR 268), natural rubber (Vietnam SVR 3L), chloroprene rubber (Japan DENKA M40). According to differences of compounds, the rubber lining has the following types: HNR, SNR, IIR and CR. According to the vulcanization methods, the rubber lining can be divided into press vulcanization, atmospheric pressure vulcanization and prevulcanization type. Seawater resistant, sodium hypochlorite resistant or low calcium and magnesium specialty rubber linings are also available.
