Tyvek 1422 A Chemical Protective Coverall With Hood
Available size in M - XXL
Serged Seam This is a simple stitched seam. It is economical, but is generally not used for chemical/splash/liquid type protection as the seams are not designed to resist liquids. It is designed for dry materials/dusts.
Sewn and Bound Seam These seams are serged, and then an overlay is chain stitched through all the layers. This provides resistance to liquid invasion, and is appropriate for liquid threats.
Heat Sealed Seam The seam is sewn and then sealed with a heat activated tape. This method provides liquid proof seams, and is used for environments where contact, not splash risk is present. i.e. you might immerse your foot or leg in the liquid by accident briefly.
Heat Sealed Plus Seam – Same as the heat sealed seam, but it is also sealed on the inside of the suit as well providing extra protection. .
