High Abrasion Resistance Industrial Asbestos Gland packing Low shrinkage
Descriptions:
Asbestos gland packing with PTFE is made of white asbestos fiber packing impregnated with PTFE dispersion. (addition of lubricant is optional.) Asbestos PTFE packing is soft in texture and suitable as the sealing of pumps for liquidated chemical. They have high wear-and scouring-resistance and compactness. Suitable for power stations, chemical, paper and pulp, food and pharmaceutical products.
It is braided from asbestos yarns impregnated with PTFE dispersion.It is a flexible, resilient,homogeneous and compact packing.The application is for the use in pumps adn valves for various kinds of chemicals(acid,alkali,oil,steam,ammonia,etc),such as sealing stuffing boxes on rotary, alternativemotion shefts, valves for coolants,medium index acids and alkalis, petrochemical and foodstuff industries.
