Tychem® LV


For quicker reference, a listing of all questions is given first, followed by questions and answers together.

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

    DuPont has submitted TychemŽ LV third party testing permeation testing against chemical agents that terrorist are likely to use, toxic industrial chemicals, and military chemical agents. (To view a list of chemical permeation data, please refer to the permeation database)  Go to top



  2. In what applications is Tychem® LV used?

    The low visibility of TychemŽ LV olive drab color helps maintain a low profile in critical domestic preparedness situations where high visibility is not desired.   Go to top



  3. How should Tychem® LV be disposed of?

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



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

    DuPont™ TychemŽ 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® LV discolor with age?

    There is no evidence that TychemŽ LV fabrics will discolor with time.  Go to top



  6. How does Tychem® LV compare to permeable military suits?

    TychemŽ LV has been tested against the six (6) most significant chemical warfare agents at exposure levels ten times those to which permeable military suits are subjected. Average breakthrough time of >12 hours was achieved with 100g/m(2) (total coverage) for all chemicals with the exception of Lewisite. Lewisite results >12 hours at 10 g/m(2) (standard test) and two hours at 100 g/m(2) total coverage.  Go to top



  7. Are garments made of Tychem® LV available in other colors?

    No, TychemŽ LV is available only in military olive green.  Go to top



  8. 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



  9. Can garments made of Tychem® LV be reused?

    DuPont considers TychemŽ 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. (See Test Methods/Standards, Decontamination Issues.) 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



  10. Can garments made of Tychem® LV 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



  11. Are garments made of Tychem® LV flame resistant and/or flame retardant?

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



  12. Can garments of Tychem® LV 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



  13. Will new chemicals be tested against Tychem® LV?

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