Tychem® 4000 S Coveralls

DuPont™ Tychem® 4000 S Serious protection you’ll love to wear

Comfortable and effective protection against a wide range of chemicals

The new DuPont™ Tychem® 4000 S coverall provides a new alternative for workers seeking safe and comfortable protection in more demanding applications. The garment’s fabric, comprising DuPont™ Tyvek® laminated with a chemical barrier film, presents wearers with optimum protection against a range of chemical environments and hazards while being supple and lightweight.

Tychem® 4000 S is ideal for chemical mixing, remediation and emergency response. It can be used in a variety of industries, including environmental clean-up operations, oil and gas, chemical engineering, hazardous material response teams and other emergency services.

Tychem® 4000 S offers a barrier to permeation by more than 100 chemicals

Tychem® 4000 S garments utilise a film laminated to Tyvek® fabric to achieve a barrier to permeation by a broad range of inorganic and organic chemicals, including phenol, ethanol and methanol.

Innovative smart design features, such as a double-zip and double-cuff systems, enhance the overall protection afforded by the garment.

A comfortable garment specifically designed for ease-of-wear

As well as providing high levels of protection, the suppleness and flexibility of the fabric results in a lightweight, comfortable garment that is easy to wear. Great care has also been placed in optimising the shape and fit of the garment, particularly when moving. Worker safety is also enhanced by the white colour of Tychem® 4000 S garments as it provides contrast across a wide range of natural backgrounds. In a laboratory study, Tychem® 4000 S received high overall ratings for visibility in dim light, bright light, and contrast with natural backgrounds.
