FAQ

1. Is it possible to wash Recycled Tyvek® / Recycled GreenShield™ or MaxShield™ garments?
   Our garments are inexpensive and designed to be disposed of, thus DuPont does not recommend
   washing.
2. Are Recycled Tyvek® / Recycled GreenShield™ or MaxShield™ garments anti-static or static dissipative?
   No. Our garments are not anti-static treated.
3. How can I dispose of Recycled Tyvek® / Recycled GreenShield™ or Maxshield?
   The recommended method of disposal is burial in a landfill in accordance with applicable local, state, national, EC and/or federal regulations.
4. Are Recycled Tyvek® / Recycled GreenShield™ or Maxshield garments flame resistant or flame retardant?
   No, Tyvek® garments are not flame resistant or flame retardant and should not be used around heat,
   flame, sparks or potentially flammable environments.
5. Can Recycled Tyvek® / Recycled GreenShield™ or Maxshield garments be used for welding applications?
   No, Tyvek® garments should not be used for welding applications. Tyvek® garments are not flame
   resistant or flame retardant and should not be used around heat, flame, sparks or potentially
   flammable environments.
6. How much chemical protection will Recycled Tyvek® / Recycled GreenShield™ or Maxshield garments provide?
   Tyvek® garments are acceptable for situations involving dry hazardous particles and aerosols.
7. Can Recycled Tyvek® / Recycled GreenShield™ garments be used in clean rooms?
   No. The recycled line cannot be sold in clean rooms.
8. Recycled Tyvek® / Recycled GreenShield™ or Maxshield garments discolor in storage or before use?
   Recycled Tyvek® / Recycled GreenShield™ or Maxshield garments may turn yellow after long-term exposure to oxidizing gases, such as nitrous oxide and exhaust from internal combustion engines.
9. What is the shelf life of Recycled Tyvek® / Recycled GreenShield™ or Maxshield garments?
   Tyvek® garments have a shelf life of at least 5 years based on hyperbaric oxidative degradation studies. High temperature, oxidizing gases, wet, cold, ultraviolet and ionizing radiation will significantly impact the long-term life of garments made of Tyvek®
10. How fluid repellent are Tyvek® garments?
    Tyvek® garment material will resist water penetration up to 1.5 psi and liquid penetration by blood at a similar level. Low surface tension liquids will penetrate at lower pressures.
11. Are Recycled Tyvek® / Recycled GreenShield™ or Maxshield garments available in other colors?
    Recycled Tyvek® / Recycled GreenShield™ or Maxshield garments are available only in white.
12. How long can recycle Tyvek® / Recycled GreenShield™ or Maxshield garments be used before discarding?
    All recycle Tyvek® / Recycled GreenShield™ or Maxshield garments are designed for limited-use; the actual use time will vary depending on work conditions and hazards present.
13. Can MaxShield™ and Tyvek® be recycled?
    Yes, non-contaminated garments used in clean room operations can be recycled for non-hazardous applications. Contact Garment Recovery Systems for additional information.
14. Are Recycled Tyvek® / Recycled GreenShield™ or Maxshield garments?
    Shoe and boot covers made of Tyvek® / Recycled GreenShield™ or Maxshield have a good coefficient of friction (CDF) and are skid resistant.
15. Can Recycled Tyvek® / Recycled GreenShield™ or Maxshield garments be used for paint spraying
    applications?
    Yes, testing on isocyanate spray paint systems show that Tyvek® can be used with isocyanate-based paints, under proper conditions. Garments made of Tyvek® are not appropriate in spray applications if they become soaked with overspray and back splatter. The well-designed spray booth should not result in excessive overspray and back-splatter. Some two-part, isocyanate-based, spray paints contain hexamethylene diisocyante (HMDI) and aliphatic isocyanate oligomers. In many isocyanate paint formations, there is less than 0.1% free HMDI present in the hardener component of the paint formulation which quickly reacts upon mixing with the other component. The aliphatic isocyanate oligomers have low vapor pressure and are present as an aerosol during spraying. Particle barrier testing demonstrates the barrier of Tyvek® to micron sized aerosols. If conditions during the spray operations do result in excessive wetting of the garment, then breathable film products, such as NexGen® or monolithic film products such Tychem® QC or CPF® 1 should be considered.
16. Can I receive discount pricing?
    Miller’s Precision Enterprises, Inc. pricing structure is set up on a Tier basis. The more cases that are purchased at a time the more cost effective the purchase cost is.
