Gaskets for Lithium-Ion Batteries
This is developed for achieving long term seal performance.
Products that deliver a sophisticated blend of material and processing properties.
These weldless products deliver a highly reliable, long-lasting seal with an elastic surface because they are manufactured with a high-molecular-weight grade of fluororesin PFA polymer using a proprietary hot-press molding technique (patent No. 3916728)
Blend of material
Fluororesin PFA with a superior properties deliver a highly reliable.
1. It maintains the great stress cracks resistance with calking seal has the characterization of high-molecular-weight for many years.
2. About a thermoplastic resin, it has the highest and a temperature resistance. Low-temperature properties are steadfast and hard temperature range of -200℃.
3. It has a high level of water repellency. Its not inducing fixing of water.
4. Excellent chemical resistance that provides compatibility with almost all chemicals and solves.
5. Flame-retardant is not only UL94 V-0 certification but also has the highest limiting oxygen 95Vol% therefore its more difficult to fire them flammable electrolytes.
6. In high current environment, it has more than 600v CTI that tracking dielectric breakdown occurs and it has the highest level to a plastic resin.
Manufacturing properties
A heat press molding manufactured products getting the most blend of material out of method to realize seal extended period of time.
1. General molded resin products provoke heat-shrink under constant temperature but our products keep perfect sealing by effects of plastic memory to expand the surfaces of the seal.
2. It’s the risk of cracking and the penetration liquid to a minimum. And there is no weld and skin layer unlike injection molding.
3. Its to improve a gas barrier raising crystallinity by the surfaces of the seal is compressed.
