    摘要: The invention provides a process, and product thereof, for forming a chemically resistant fusion bonded seal between chemically dissimilar materials by use of a chlorinated polyolefin film for protective garments. The process involves placing the chlorinated polyolefin film between two dissimilar films such as a facepiece and the fabric film of the garment and applying heat and pressure. The resulting fusion bonded film composite is strong, flexible and upon the application of sufficient stress exhibits total cohesive rupture failure.

    摘要: The invention provides a process, and product thereof, for forming a chemically resistant fusion bonded between chemically dissimilar materials by use of an acid-based terpolymer for protective garments. The olefin terpolymers are preferably copolymers of an olefin, an acid and an ester. The process involves placing the olefin terpolymer film between two dissimilar films such as a facepiece and the fabric material of the garments and applying heat and pressure. The resulting fusion bonded film composite is strong, flexible and upon the application of sufficient stress exhibits total cohesive rupture failure.

    摘要: The present invention relates to antistatic polymers containing a mixture of a thermoplastic resin and about 8-20% by weight of conductive partially carbonized chopped linear carbonaceous fibers. The chopped carbonaceous fibers have a carbon content of about 70-85% by weight and an electrical resistivity of about 10.sup.-2-10.sup.3 ohm-cm. The composite has a surface resistivity of about 10.sup.4 -10.sup.10 ohms/square. These intermediate surface resistivities make the composite an excellent choice for use with plastic parts that come into direct contact with electronic components and circuitry.
