pH-Ene Nitrile Material Covering Rubber Conveyor Belt Convey Materials of Acid and Alkali

Model NO.: pH-ene Nitrile material covering rubber conveyor b Application: Industrial Component Cross-Section Shape: O-Rings Transport Package: Roll Origin: Weifang, Shandong, China Material: Silicone Rubber Effect: Hole with Seal Trademark: YM Specification: good quality HS Code: 40101200 pH-ene Nitrile material covering rubber Conveyor Belt convey materials of acid and alkali This kind of product is suitable for the acid and alkali contact condition, eg phosphoric fertilizer, abstracts salt from sea water The covering layer rubber is the mixture of rubber and plastic and filled with acid resistant and alkali resistant inert materials, which is much better than LDR acid and alkali resistant conveyer belt. The framework material is EP canvas, is more reliable and more alkali resistant and the cotton canvas core belt. Generally it is made into dng shaped.  Application:  Suitable for chemical industry such as fertilizer industry, paper making industry, cement industry etc. conveying acid/alkali-forming materials. Characteristics ·Chemicals and corrosion resistant and highly durable physical properties ·Good elasticity, small elongation at rated load ·High adhesion, good flexibility and trough ability;
