Fiberglass Paste Mat

AGM Battery Separator

Fiberglass Paste Mat

The fiberglass paste mat is an essential component in the construction of lead-acid batteries, particularly in the design of the negative (or sometimes positive) plate. It can contribute to the overall performance and longevity of the battery.The fiberglass paste mat in a lead-acid battery plays a crucial role in ensuring proper electrolyte distribution, active material support, and overall battery performance. It contributes to the battery's ability to deliver reliable power over its operational lifespan and helps maintain consistent performance through various charge and discharge cycles.

    The mat material made of glass fiber and acrylic acid has the following characteristics:


    A high performance paste paper is prepared from an acid - resistant fiber.The acid resistant fiber is alkali free acid resistant glass fiber. It has effectively solved the problems of lead-acid battery paste paper poor temperature resistance, easy bonding to plates, high water content, weak acid absorption ability and different dissolving rate of sulfuric acid under existing technology: This paper paste plate has strong ability of acid absorbing and liquid protection and has good flexibility, high porosity, be advantageous to the battery formation, effectively reduce the battery internal resistance, acid and high temperature resistant, non-stick to plate, using it in the production of lead-acid battery does not have the problem of initial small discharge current, with superior performance of no late self-discharge, no difference of battery capacity and low temperature. 


    The internal resistance of fiberglass past mat is smaller than the pulp paste board paper, the structure is stronger than the pulp paste board paper, post-discharge not easy to fall off. paste paper price moderate, suitable from general performance requirements to high performance requirements of lead-acid batteries.Width can be divided according to customer requirements.
