ABSTRACT:
A protective material comprising a layer of vinylidene chloride or saran or polymer or copolymer of vinylidene chloride between two layers of polyethylene or other polyolefin to provide protection against both permeation and breakthrough. A cloth backing or inner layer can be added to this material for comfort. The material can be modified with a reinforcing material such as fiberglass or scrim cloth. Inclusion of an indicator substance between layers, or impregnated in a layer, provided further protection by warning the user of permeation and breakthrough. This material can be utilized in protection clothing such as gloves, as enclosures for instruments and equipment, as a container, and in other applications. The material is preferably formed by first surface oxidizing one or more layers of polyethylene and/or vinylidene chloride or saran or polymer or copolymer of vinylidene chloride, or removing halogen sites from a layer of vinylidene chloride or saran or polymer or copolymer of vinylidene chloride, and then pressing the layers of vinylidene chloride and polyethylene together under heat and pressure such as 330 degrees Fahrenheit at 400 PSI. The protective material can include one or more layers of polyolefin including an electrically conductive material, for electrostatic discharge protection.
