Crypton uses a patented system to encase textile fibers with a proprietary copolymer formula P385. Crypton offers stain, moisture, mold, mildew, bacteria and odor-resisting protection. It is not a surface treatment, but a textile that is transformed through a series of processes. Initially embraced by the healthcare industry, Crypton is also used in hospitality and contract industries and rapidly gaining popularity in residential markets
Crypton does not contain any toxic chemicals, heavy metals or carcinogens that can be leached out with water or upholstery cleaners. Crypton Super Fabrics do not contain air polluting VOCs. Crypton uses no PFOAs (perfluorooctanoic acids) during its manufacturing process. Crypton uses no formaldehyde and does not contain vinyl.
Crypton is UFAC Class 1, and it passes the normal Cal. 117E and NFPA 260 requirements. Crypton can be treated to pass Cal. 133 (with components), IMO RES 16-52A, CRIB 5, Boston and New York Fire Codes, automotive FMVSS302 requirements, and aviation FAR25-853.
The test for breathability (ASTM-E96) measures the amount of vapor that can pass through the fabric. The pores formed in Crypton's treatment are large enough to let water vapor pass through but small enough to keep water out.
