Lead Acid Battery Separator
LAB Separator for 
OVERVIEW
The importance of lead-acid batteries cannot be understated. They are used in many different applications, including in automobiles and forklifts. Generally, ultra high molecular weight polyethylene (UHMWPE) in a molecular weight range from 3 to 5 million g/mol is generally used as a raw material for the battery separators that are important components of lead-acid batteries.
It is necessary for the UHMWPE to be high quality to ensure long-term safety in operations in all kinds of conditions. SUNFINE™ boasts optimal grade designs and high quality that enables customers to provide high product quality.
