Filtration Foams for
the World

Our filter foams are designed with the future in mind. We pay close attention to emerging trends and incorporate them into our product and process development. Environmental considerations are fundamental to filter foams. Keeping contaminants contained, filter foams play a vital role in keeping our environments comfortable and clean.

By continually reimagining how products are utilized, we continually develop new methodologies and formulations adding value across the board to consumers, manufacturers, and the environment.
The FilterPore Series consists of thermal reticulated polyurethane foams – open-cell foams that offer consistent pore size, are strong and easily fabricated, durable, and customizable. The flexible skeletal foam structures are extraordinarily versatile materials that can be fabricated into a multitude of different products and applications customizable to meet filtration requirements. They can also be combined with other types of media to produce unique compositions to meet unique needs.

WITP foam filters present high-quality characteristics such as high tensile, elongation, and low tear properties, making them compatible with fabrication techniques such as cutting, shaping, stapling, tacking, stitching, cementing, laminating, and grommeting.

Polyurethane Foams

Transportation

Our polyurethane foam products accommodate air seals, water seals, and gasket seals. 

Lightweight, open-cell structures with low combustibility offer effective seals for automotive lights, side mirrors, ducts, exterior and interior applications.

 

Ceramic Foam Filters

Foundry

Our high-quality FilterPore™ ceramic foam filters were developed to remove impurities from molten metal in the casting process at foundries.

Purification Filter Foams

Industrial Water Treatment, HVAC Systems

Our polyurethane foam filters prevent unwanted contaminants
and particulates from entering an environment. 

This cell-controlled technology prevents particles from passing through systems such as municipal water treatment facilities and industrial HVAC systems (Heating, Ventilation and Air Conditioning).
