Why Microtex is considered the best
PT Bag Manufacturers in India
Established in 1969,
Microtex PT Bags are known for its legendary quality
Microtex PT Bags are known the world over for their dependable & reliable performance in the battery. PT Bags manufactured by Microtex are made from selected high-tenacity polyester yarns from the best of polyester yarn manufacturers. This ensures the tubular bags do not react to the harsh acidic environment inside the lead acid battery
What are Tubular Bags?
Microtex PT Bags (Tubular bags or multi-tube Gauntlets) used in the production of tubular battery plates are an innovative and welcome import substitute for industrial lead-acid battery manufacturers in India – pioneered by the manufacturers of the legendary Microtex battery and separators, 50 years ago. A result of the persistent and completely indigenous research and inventive enterprise of our founder Mr A Govindan, who held a Patent for the Tubular Bags issued in 1975 by the Trademarks & Patent Registrar, India.
- Engineered woven Tubular Bags are made from technical textiles & are used as oxide holders for the production of tubular positive plates in lead acid batteries.
- Microtex Tubular Bags are stringently tested in house for chemical and electrical properties, meeting and exceeding the norms. High-performance batteries made from our PT Bags have met the severe endurance test as per IS 1651 in Stationary cells and Life-cycle tests as per Indian Railway specifications for high cranking currents in Diesel Locomotive Starter Batteries.
- Microtex Tubular Bags are –
used in all tubular batteries like – - UPS, Inverter batteries traction battery manufacturers in India
- in high-end industrial applications like Railway Locomotive Battery, Train Lighting batteries and Signaling battery,
- in high-performance stationary cells – OPzS and OPzV with a designed life of 20 years – requiring a zero defect, zero failure of tubular bags,
- used by tubular battery manufacturers and for Tubular Gel battery applications both deep-cycle batteries demanding a robust construction of the Tubular Bag
- Regularly exported for naval applications in the manufacture of Submarine Batteries by world-class battery manufacturers
