Rechargeable batteries or secondary batteries contain active materials that can be regenerated by charging. When the energy produced by rechargeable batteries drops below optimum efficiency, secondary batteries may be recharged in a couple of ways, depending upon their construction. 

Lithium batteries are primary batteries with a lithium anode.  They are disposable.

Disposable primary batteries are replaced once the energy supply is depleted. Their energy is produced when the materials within the battery react and are exhausted.

Battery packs are constructed from two or more individual cells or batteries.

Industrial batteries translate chemical energy into electricity.

Thermoplastics and thermoplastic materials soften when heated and harden when cooled. They can withstand many heating and cooling cycles and are often suitable for recycling.

Filtration media and elements are designed to remove suspended particles from a process stream. This product area includes bulk filter media, cartridges, housing-only products, and housing and filter assemblies. 

Plastics and plastic materials are organic, synthetic or processed polymers that are supplied as raw materials or stock shapes. They typically consist of thermoplastic or thermosetting resins and can be made into many forms.

Plastic and rubber balls are sphere shapes that are used as check or ball valves, bearings, and in other applications.

Gas filtration elements are designed to remove particulates from a gaseous process stream. They are used in natural gas processing systems and gas extraction applications.

Filtration media is material that actively separates solids from a solution and/or binds select materials in a solution.

Liquid filtration elements are used to remove impurities from liquids. They are used in water treatment systems and fluid processing applications.

Organic, pharmaceuticals and fine chemicals contain carbon in their molecular structure.

Specialty fibers, fabrics and textiles are based upon a unique composition, weave, or technology, and are designed for specialized applications.

Panels and panel materials are composite structures which consist of multiple layers or skins bonded to or sandwiching a core material such as multilayer sheets, cored laminates or industrial structural panels.
