Flex-Sil®

Flex-Sil®

The Antidote for Antimony Poisoning

Preferred by OE applications, Flex-Sil® offers excellent antimony suppression for increased life of flooded lead-acid batteries.

Flex-Sil® is made from natural rubber, amorphous silica, and other minor ingredients. Introduced in 1978, Flex-Sil® quickly became the battery separator of choice for many deep-cycle applications where the battery needed to overcome antimony poisoning, and is still the best option to increase battery performance and decrease maintenance costs.
