Polypropylene foil-bonding agent-metal composites are disclosed, in which polypropylene modified by carboxyl groups and/or anhydride groups is used as bonding agent. In order to produce the polypropylene foil, polypropylene random copolymers are used which are constituted of 90 to 99 % by weight, preferably 93 to 99 % by weight, propylene and 1 to 10 % by weight, preferably 1 to 7 % by weight, com...

An insulating composition comprises a polyolefin, preferably polypropylene, and hollow microspheres, at least some of which have been pre-treated with a chain-scission agent and, optionally, a functionalizing agent for the polyolefin, before addition to the polyolefin melt. The provision of the chain-scission on the microspheres enables the microspheres to be compounded substantially without break...

Disclosed are films or sheets comprising a crystalline propylene polymer composition which is comprised of, by weight, (A) from about 30 to 65% of a copolymer of propylene with a C4-8 alpha-olefin containing from 80 to 98% propylene, and (B) 35-70% of a co- or terpolymer of propylene with ethylene and, optionally, a C4-8 alpha-olefin having an ethylene content of 5 to 10% when ethylene is the sole...

A resistor has a resistor body (11) of polycrystalline silicon and electrical terminals (23, 15) arranged on and/or in the resistor body (11), so that a resistor portion (13) is formed between the terminals and produces the useful resistance of the resistor. The material of the resistor body is doped with dopants of both acceptor type and donor type. In order to block the charge carrier traps at g...

The static field is given a voltage of up to 60 000 volts. The water current is fed to a vertically flowing flue gas current after it has passed the static field. The device incorporates a feed conduit (1) for the flue gases, components (2) connected to a voltage source (3) for producing a static electrical field in the feed conduit, a sepg. conduit (5) connecting to the feed conduit, and a compon...
