Flex-Sil®

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.

Product Overview

CellForce® is a hybrid rubber/PE battery separator designed for industrial traction and deep discharge cycling in lead-acid battery applications. The highly flexible CellForce® combines the strength and handling characteristics of PE with the electrochemical advantages and reliability of rubber. This enables the battery assembly process to be more flexible while enhancing battery cycle life by positively affecting top-of-charge voltages and reducing normal in-service maintenance.

Ace-Sil®

With a life expectancy of up to 20+ years, Ace-Sil® is ideal for backup power applications used in telecommunications infrastructures, nuclear power plants, and military facilities. In use since 1934, Ace-Sil® is the only battery separator qualified by the U.S. Federal Energy Regulatory Commission (FERC) for use in certain nuclear applications.

Product Overview

Ace-Sil® is formulated from natural rubber, amorphous silica, sulfur, and other minor ingredients. Sulfur vulcanized to hard rubber form, Ace-Sil® is commonly utilized in float or standby applications for flooded lead-acid batteries with life expectancies of 20+ years. Process refinements have enabled patterns and thinner backwebs that lower electrical resistance and improve electrolyte mobility. Permanent wettability gives low resistance instantly upon exposure to even higher gravity electrolytes. Ace-Sil® offers superior physical characteristics for extended life.
