Hindustan Nylons Standard Fluoromers Pvt. Ltd. Manufactures Glass Fibre made Fillers. Hindustan Nylons Standard Fluoromers Pvt. Ltd. Is an ISO 9001:2008 certified company. The Glass Fibre made Fillers improves the creep resistance of Polytetrafluoroethylene- PTFE, both at low and high temperature. It is chemically stable [except to strong alkalis and hydrofluoric acid - HF].It has little effect on the electrical properties of PTFE, and improves its wear and friction behavior. A not uncommon problem with glass-filled PTFE is discoloration of the finished parts, in particular on the inside of large billets. The glass used in PTFE compounds has been treated by a proprietary process to reduce this discoloration.
