Independent tests confirm permeation resistance

Tests conducted by an independent laboratory show that Tyvek L1431N fabric has a high barrier performance that provides excellent protection against liquid permeation.

Protective coveralls can all look the same making selecting the best protection a challenge. Permeation tests (according to EN ISO 6529 - Method A) were conducted to determine the breakthrough times of commonly used chemicals with Tyvek, MPF (Microporous Film) and SMS (Spunbond-Meltblown- Spunbond) - materials that are frequently used for type 4, 5, and 6 single-use chemical protective clothing. Tests revealed that Tyvek offers long-term protection of up to eight hours.

To further help in the selection process DuPont has developed a series of videos featuring Professor Victor Tytonius, the cyber scientist who specialises in worker protection. View the videos at: www.differentprotection.tyvek.com
