Protection, durability, and comfort

  • Pros: Excellent protection against particulate matter
  • Great splash resistance
  • Lightweight and durable

Tyvek is a general-purpose material that’s lightweight and versatile, resilient and durable. PPE made from Tyvek can provide inherent barrier protection against lead, asbestos, mold and a variety of airborne hazards.

Tyvek is best used in PPE for those in the medical industry, research and anywhere that requires sterile environments. However, Tyvek should only be used to protect against a light liquid splash. That’s why it performs best against dust, airborne particles and related hazards. Tyvek is available in coveralls, gloves and related PPE.

TYCHEM® Protective Apparel


Serged or sewn




Double taped

  • Pros: Excellent protection against most chemicals
  • Great splash resistance
  • Variety of seam options for more protection

Tychem serves as your ultimate chemical defense. It’s a reinforced material that defends against a wide variety of biological and chemical hazards. Accredited by third-party labs and tested for permeation effectiveness against hundreds of chemicals, Tychem was developed for your peace of mind. Note that Tychem garments are tested for its permeability, which is a very exacting test that measures how much hazard can move through the garment on a molecular level.

Tychem suits are also made using a variety of seam styles to match your needs, as different seams work better against different hazards. All this protection does come at a slight cost to comfort and weight, but Tychem remains the best option for heavier chemical work. Workers who wear full Tychem coveralls know they’re receiving the best possible protection against heavy chemical spills.
