PTFE Seals
Parakh Rubber House offers PTFE Seals. The PTFE material is characterized by a series of outstanding properties: PTFE has the widest working temperature range. The surface is slippery and repels most media. Its use is favoured in all cases where the retention of residues is to be avoided. PTFE is non-toxic at working temperatures up to + 200 °C. The coefficient of friction is very low against most opposing surfaces made of other materials. Stiction and friction are almost the same. The electrical insulating properties are outstandingly good. They are almost independent of frequency, temperature and weathering effects. The chemical resistance exceeds that of all other thermoplastics and elastomers. Thus the resistance to swelling is good in almost all media. Liquid alkali metals and a few fluorine compounds attack PTFE at higher temperatures and pressures. PTFE still has some elasticity and therefore it can be used for seals and constructional parts. With lip seals, provision must be made for a constant additional contact pressure by the use of springs or by other means. Grades: - High Performance Grade TEFLON/ FLUON/ HOSTAFLON/ HIFLON & PTFE is Filled With Graphite, Glass Fibres, Bronze And Carbon To Achieve Special Properties. Applications: - Gaskets, O-rings, Bushes, valve seats, Flate-rings, V-rings, Step-seals, Piston-seals, bellows, impeller, sleeves, hydraulic seals, etc.
