Chemical Resistance
Dureflex® brand polyurethane film may offer better chemical resistance in comparison to flexible PVC. However, several factors can impact performance, so each potential application must be evaluated before a formulation is selected. Factors that influence chemical resistance include full immersion or intermittent contact with various agents, temperature, gauge, pH level, molecular weight, hardness, and whether the film is a polyester- or polyether-based product.
Polyester- and polyether-based Dureflex® polyurethane film provide excellent resistance to the following:
Polyester polyurethanes *
Sulfuric acid (20%); ASTM fuel A; oil #1, #2 and #3; butane; dioctyl phthalate; ethylene glycol; gasoline (100% octane); kerosene; turpentine; saturated calcium chloride solution; Freon 12; hydrogen sulfide (5%); Mr. Clean®; saturated sodium chloride solution; and synthetic perspiration
Polyether polyurethanes *
Acetic acid (5%); ASTM fuel A; oil #1 and #2; butane; ethylene glycol; kerosene; detergent oil 20W; non-detergent oil 20W; transmission oil 20W; turpentine; Clorox® (5%); saturated calcium chloride solution; Freon 12; hydrogen sulfide (5%); saturated sodium chloride solution; synthetic perspiration; Tide® detergent (1%); and water
* At room temperature, exhibits little to no change, or slight loss in properties and swelling
Applications include: seals; gaskets; flexible hoses or chutes; belting; hazardous material gear; tank and pipe linings; settling pond linings; and glove box ports.
