Halar Coated Diaphragm

We are recognized as one of the prominent manufacturers and suppliers of wide collection of halar coated diaphragm.

Combination of properties as a result of its chemical structure a a 1:1 alternating copolymer of ethylene and chlorotrifluoroethylene.
HALAR fluropolymer offers excellent chemical resistance and is not effected by aromatic, aliphatic & chlorinated solvents, it also doesna t react with Bases, Salts , Strong bases, Salt water, Hydraulic fluid , Lube oil , De ice fluid , Strong acids , Strong oxidants , UV light , Petroleum, Fungus. It has a little effect on Esters & Keytones, No known solvent dissolves or stress cracks the polymer at temperatures up to 120A C ( 250A F )
HALAR fluropolymer has good electrical properties, broad use temperature from cryogenic to 160A C (310A F) and meets the requirements of the UL a 94 V- 0 vertical flame test in thickness as low as 7 mils. It is a tough material with excellent impact strength over its broad use temperature range. HALAR ECTFE also maintains useful properties on exposure to cobalt 60 radiation at dosages of 200 megarads. It is one of the best fluropolymer for abrasion resistance.
