    4. Enhanced Elasticity; Resilience in Compression of Active materials 
    5. No impurities present; Chemically clean & pure
    6. Very low weight loss; does not disintegrate inside the battery
    7. Excellent Oxidation Resistance; very long life
    8. Dimensionally stable; does not get affected in sulphuric acid inside the battery
    9. Very small pore size; Ensures retention of active mass & avoids shedding
    10. Mechanically very strong; no failures due to bursting of tubes
    11. Engineered Profile; Ease of use in shop floor  

    Microtex Energy Bags (Pluri Tubular Woven Gauntlets) used in 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 famous 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 Pluri Tubular Bags issued in 1975 by the Trademarks & Patent Registrar, India

MICROTEX PT Bags  for tubular battery are regularly tested in house for dimension stability, oxidation resistance, electrical resistance, tensile strength and are found to surpass our specifications.

Microtex is an ISO certified company

Engineered woven gauntlets - PT Bags for tubular battery

What are PT Bags?

  • PT Bags, Pluri Tubular Gauntlets or Tubular Bags as they are commonly called are oxide holders for the tubular battery positive plate. A spine grid replaces the flat grid in a flat plate battery; the spine grid is inserted in one end of the PT Bag and filled with oxide from the other end, completely enclosing the spine grid which makes it protected from corrosion. The open end is locked with a plastic bar and you have a tubular positive plate – which are very robust and has a very long life compared to a flat plate battery.

Microtex have been manufacturing Pluri Tubular bags since 1969

Microtex pluri tubular gauntlets

  • Available in a variety of profiles
  • PT Bags or Pluri Tubular Bags or just Tubular Bags are used as oxide holders in Industrial Tubular battery plates in Lead acid batteries. It is a vital component of the Lead acid battery made from polyester fabric it ensures the high performance requirements of heavy duty traction batteries and standby stationary cells. The tubular bag surrounds the rod shaped electrodes called spines joined at the top to form a bus bar, and filled with lead oxides, one end serves as the bus bar and the open end is locked with a plastic bottom bar. The tubular bag construction is highly microporous and ensures free flow of electronic ions during the chemical reaction when the plates are charged or discharged, for a high performance of the battery. The fabric design ensures that the active material shedding is practically eliminated and as the spines are covered by the active material, corrosion is much slower and inhibited compared to flat plate batteries. Although the recent lower cost non woven gauntlets have taken a space in the market because of lower costs, the woven gauntlets are superior in strength and will not rupture easily in Tubular gel batteries with a designed life of 20 years.
