Acid/Alkali Resistant Conveyor Belt
Shandong Longyuan Rubber Co,.Ltd is located in Dongying city, Shandong province, which is one of the leading manufacturers in development,design ,manufacturing and marketing of rubber products in china.
In order to meet the clients’requirement to convey materials with chemical corrosiveness, when design and manufacture, we use nylon, cotton or EP fabric as core, which makes the belt with good elasticity, troughability and low elongation. And adopt chemical resistant materials mixed with rubber as cover, which makes the belt with good performance in acid and alkali-resistance.
Application:chemical factory, chemical fertilizer factory, paper mill, mining industry, etc.
