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.

Why Microtex are considered as leading
Battery Separator Manufacturers
Established in 1969, Microtex Battery Separators are known for its legendary quality
Microtex Battery Separator reviews are known the world over for its dependable & reliable performance in the battery. PVC Battery separator resistance is lowest & is made from a special grade of virgin poly vinyl chloride from the best PVC manufacturers globally.
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
