  1. What chemical testing has been done on Tychem® BR?

    DuPont has submitted Tychem® BR to third party testing against the ASTM F1001 Chemical Test Battery, as well as additional common hazardous chemicals. (To view a list of chemical permeation data, please refer to the permeation database.)   Go to top



  2. In what applications is Tychem® BR used?

    Light to moderate splash in industrial settings, petrochemical processing, and remediation.  Go to top



  3. How should Tychem® BR be disposed of?

    Disposal of garments made of Tychem® BR should be handled in the same manner as the hazard for which it was used. Discarded Tychem® BR garments should be mutilated to prevent unauthorized reuse.  Go to top



  4. What is the shelf life of Tychem® BR?

    DuPont™ Tychem® garments contain materials, including gloves, for which there is no specific shelf life data available. It is suggested that garments be labeled and retired to "Training Use Only" after five years. Garments may be used as long as they pass the ASTM F1052-97 pressure test and pass a full visual inspection. Uncontaminated garments that do no pass a pressure test or fail a visual inspection should be retired and labeled "For Training Use Only" or be discarded.  Go to top



  5. Will Tychem® BR discolor with age?

    There is no evidence that Tychem® BR fabrics will discolor with time.   Go to top



  7. Will ultraviolet rays damage the material?

    Yes, ultraviolet rays can damage most chemical suit materials; however, in order for damage to occur the material would have to be exposed to direct ultraviolet rays for weeks at a time.  Go to top



  8. Can garments made of Tychem® BR be reused?

    DuPont considers Tychem® garments to be limited-use garments and reuse is based on both an evaluation of the physical state of the garment and also the level and type of chemical exposure. The permeation tests indicate breakthrough time after the material has been exposed. The duration is from the initial chemical exposure NOT the total hours a garment is worn.  Go to top



  9. Can garments made of Tychem® BR be repaired?

    DuPont limited-use suits are not designed to be repaired. The suits are inexpensive, and being made from film laminates, are not designed for long-term, repeated wear.

    DuPont recognizes that in some instances minor repairs may be necessary on a new suit or a suit worn, but not contaminated. In these cases, contact DuPont Protective Apparel Customer Service for information and costs of associated with such repairs. DuPont will accept no suit returns without prior arrangement and documentation.  Go to top



  10. Are garments made of Tychem® BR flame resistant and/or flame retardant?

    No, Tychem® fabrics are not treated for flame resistant or flame retardant and should not be used in potentially flammable or explosive environments. Tychem® Reflector is the only fabric to pass the Flame Impingement Test (ASTM F1358).  Go to top



  11. Can garments made of Tychem® BR be recycled?

    No, these products are made from several different thermoplastic resins. They should never be put in with paper waste, which will be re-pulped. These products are not readily biodegradable.   Go to top



  12. Will new chemicals be tested against Tychem® BR?

    Yes, we will order additional testing as interested customers request chemicals be tested for specific needs.

    DuPont will test a chemical against Tychem® BR at no charge, on a confirmed order of at least four Level A suits or four cases of Level B coveralls.   Go to top
