Cartridge Construction

BetaPure utilizes state of the art fiber technology combined with innovative process technology to provide a clean, rigid filter structure with consistent and reproducible filtration characteristics.

BetaPure is available in two bicomponent fiber systems
1. Polypropylene/Polyethylene
2. Polyester/Copolyester

BetaPure is constructed using long, bicomponent fibers, each fiber having an inner core of polypropylene and an outer sheath of polyethylene, BetaPure performance Engineered "Z" Grades have special integral inserts designed to achieve precise removal characteristics and optimize flow and service life. The bicomponent fibers can be thermally bonded because of the difference in melt temperatures between the two components. Heating the matrix to the melt temperature of the polyethylene sheath, but below that of the polypropylene core, causes the fiber to fiber bond at each contact point, without fiber shrinkage or polypropylene degradation. The high degree of fiber to fiber bonding eliminates the need for a core support and any possibility of media migration.

Polyester BetaPure is constructed by using long bicomponent fibers of polyester and copolyester. This fiber matrix has wide solvent and chemical compatibility and is suitable for many high temperature applications.
