Battery Separators

Battery Separator manufacturers in India

Battery Separator Description: What is a battery separator? Battery Separators are microporous diaphragms placed between the negative and positive plates of lead-acid batteries to prevent any contact between them to avoid internal short circuit but at the same time allow free circulation of the electrolyte.

What is a Battery Separator?

Battery Separator material for T Gel battery & all lead-acid batteries

The PVC battery separator films was developed for the first time in India under the brand name MICROTEX with own know how and with indigenous designed machinery 50 years ago. The plant and machinery comprise battery separator sintering machines and other electrical
installations, with own captive power generators, for the smooth and automatic production of over a hundred million separators per
annum, the largest and most renowned manufacturers of PVC separator materials in India.

This kind of PVC battery separator requirements has a maximum pore size of less than 50-micron meter and lower electrical resistance of less than 0.16 ohm/cm sq. PVC battery separators are uniform in quality, free from holes, broken corners, splits, embedded foreign material, surface rupture, physical defects, etc. PVC battery separator have a very low electrical resistance which reduces internal loss saving on electric energy and improving battery performance.


The high porosity in the PVC battery separator ensures easy diffusion of electrolyte and movement of ions guaranteeing battery performance even at high discharge rates. Being completely non-reactive to acids, active materials and emitted gases, It enhances the active life of the lead-acid battery and is an ideal choice for Tubular Gel Batteries with a designed battery life of 20 years – PVC Battery Separator will not disintegrate unlike some other types of battery separator. Because of these tremendous benefits, PVC battery separator are exclusively used in Plantè Batteries, Tubular Gel Batteries, Flooded OPzS cells and Flooded Nickel Cadmium Cells.

Here is the perfect separator if you want trouble-free battery performance


Microporous battery separator requirements

MICROTEX PVC separators surpass IS specifications IS: 6071 1986 and have been tested and certified by the Central Electrochemical Research Institute, CSIR, Chennai to conform to IS specifications
Our chemical labs are equipped with state-of-the-art high-quality equipment to test our separators for all chemical, mechanical & electrical properties to ensure your batteries are made with the best quality separators.

MICROTEX battery separators, combining the outstanding characteristics of low electric resistance, chemical cleanliness, higher porosity,
Low pore size, superior corrosive resistance and with minimum level of oxidizable organics, make themselves extremely usable for
automobile, traction, stationary, train lighting, Locomotive starting applications and all other lead acid batteries.
