Tychem® TK Technical Data Sheet - 1

CHEMICAL PROTECTIVE CLOTHING Our Highest Level of Protection NFPA 1991 Test Results (2005 Edition) Tychem® TK is specifically developed for protection against toxic, corrosive gases, liquids and solid chemicals. This high-performance chemical barrier fabric is ideally suited for industrial, HazMat, and domestic preparedness applications Tychem® TK offers proven protection with proven performance over a wide range of chemicals Tychem® TK exhibits outstanding chemical barrier properties An extremely durable fabric that's puncture- and tear-resistant, its barrier has been tested against 260 challenge chemicals with no observed breakthrough after exposures of up to 8 hours. Excellent permeation data from stringent ASTM testing substantiates the uncompromised protection available with Tychem® TK is available in totally encapsulated vapor protective Level A suits and liquid-splash protective Level B suits. It is also available in ensembles certified to the NFPA 1991 chemical/ biological option. The lime-yellow color of Tychem®TK is highly visible in both bright and dim light, offering greater safety in emergency situations Suit Visor Seams Visor Seams Gloves Test Chemicals Acetone pass pass pass pass pass Acetonitrile pass pass pass pass pass Anyhydrous ammonia gas pass pass pass pass pass 1,3-Butadiene gas pass pass pass pass pass Carbon disulfide pass pass pass pass pass Chlorine gas pass pass pass pass pass Dichloromethane pass pass pass pass pass Diethylamine pass pass pass pass pass N,N-Dimethylformamide pass pass pass pass pass Ethyl acetate pass pass pass pass pass Ethylene oxide gas pass pass pass pass pass n-Hexane pass pass pass pass pass Hydrogen chloride gas pass pass pass pass pass Methanol pass pass pass pass pass Methyl chloride pass pass pass pass pass Nitrobenzene pass pass pass pass pass Sodium hydroxide, 50% pass pass pass pass pass Sulfuric acid (cone.) pass pass pass pass pass Tetrachloroethylene pass pass pass pass pass Tetrahydrofuran pass pass pass pass pass Toluene pass pass pass pass pass Cyanogen chloride gas (CK) pass pass pass pass pass Phosgene gas (CG) pass pass pass pass pass Dimethyl sulfate (DMS) pass pass pass pass pass Hydrogen cyanide gas (HCN) pass pass pass pass pass Sarin (GEi)* pass pass pass pass pass Mustard (HD)** pass pass pass pass pass Liquefied Gases Ammonia (-70°C) pass NA pass NA pass Chlorine (-70°C) pass NA pass NA pass Ethylene Oxide (-70°C) pass NA pass NA pass "Cumulative permeation <0.00945 ug/cm2 in 60 minutes "Cumulative permeation <0.0011 ug/cm2 in 60 minutes

Tychem® TK Technical Data Sheet - 2

Permeation Data for ASTM Recommended List of Chemicals for Evaluating Protective Clothing Materials (ASTM F1001) Chemical Name Physical Phase Average Normalized Breakthrough Time, min Carbon disulfide Ethyl acetate Ethylene oxide Hydrogen chloride Methyl chloride Average Permeation Rate, µg/cm2/min Index of Codes: > = greater than; < = less than; L = liquid; G = gas Numbers reported are averages of samples tested by the ASTM F739 test method. Sample results do vary and therefore averages for these results are reported. For a complete list of permeation data, please visit our website at...
