Interstate Specialty Products die cuts cellulose acetate membrane filters for water filtration and purification, reverse osmosis, and many other applications.

Interstate Specialty Products die cuts cellulose acetate membrane filters from sheets and rolls into discs and other shapes. For over 50 years, we’ve been using precision die cutting to create custom cellulose acetate (CA) membrane filters at our Made in the USA company in Sutton, Massachusetts.

Today, our converting capabilities include cleanroom cutting for medical, pharmaceutical, and other high-purity applications. Digital knife cutting of cellulose acetate membranes into disc filters is also available, and can provide tight tolerances without tooling costs.

Die Cut Cellulose Acetate Membrane Filters

Die cut cellulose acetate membrane filters exhibit high strength, low static charge, and good resistance to heat. They can be sterilized repeatedly without loss of integrity, and are a good choice for very low aqueous extractables. Applications include water filtration and water purification systems.

Die cut cellulose acetate membranes are also recommended for use some acids and alcohols. These die cut membrane filters from Interstate Specialty Products are a proven alternative to thin-film composite reverse osmosis membranes.

Custom Cellulose Acetate Membrane Filters

Ask Interstate Specialty Products if custom die cut cellulose acetate membrane filters are right for your application. If you need greater resistance to low molecular weight alcohols, die cut nitrocellulose filters made of mixed cellulose esters may be a better choice because of their higher porosity and flow rates.

Laboratory applications for die cut cellulose acetate membrane filters include biological and clinical analysis that requires maximum protein recovery. This semipermeable membrane material is available in diacetate and triacetate grades, or blends of the two.
