Polyolefin composition suited for metal coating by flame spraying

Process for repairing plastic coatings of metal pipes

Disclosed is a process for coating the inner surface of metal containers by deposition of specific polyolefin compositions on the separate parts of the containers, subsequent assembly of the parts and melting of the polyolefin compositions.

Process for coating the inside surface of metal containers with

Disclosed are functionalized polyolefins prepared by mixing a polyolefin with a concentrate and extruding the resulting blend, where the concentrate is in the form of olefin polymer particles coated with a mixture of additives including:

Concentrates suitable for the preparation of functionalized polyolefins

Polyolefin compositions, capable of developing substantial dielectric heat including (percent by weight):

Polyolefin compositions suitable for sheets and films which are sealable

Apparatus for coating the interior surfaces of metal containers by electrostatic deposition of specific polyolefin compositions on the separate parts of the containers prior to assembly of the containers and melting of the polyolefin compositions, which includes

Apparatus for coating the inside surface of metal containers with

Parts of coatings made of plastic material on metal pipes, that have either been removed or damaged, are repaired by using one or more segments of a hollow cylinder having an inside radius equal to the outside radius of the metal pipe and an outside radius equal to the sum of the outside radius of the metal pipe plus a length from 80% to 120% of the thickness of the coating, said hollow cylinder segments being made up of a polymer composition, preferably foamed, comprising (percentages by weight):

Process for repairing plastic coatings on metal pipes

Process for coating metal pipes, where the coating materials used are specific polyolefin compositions partially crosslinked by grafting the polyolefin backbone with an alkenyl-substituted alkoxysilane and then reacting the grafted polyolefin with water.

Process for coating metal pipes with polyolefin materials

Polymer composition comprising a propylene polymer matrix containing (percentages by weight with respect to the total composition):

Polypropylene composition with a high content of heavy mineral

Disclosed is a process for repairing removed or damaged parts of plastic coating on metal tubing characterized in that the coating material or the adhesive for patches or bands is an adhesive polymer composition comprising by weight:

Process for repairing exposed or damaged parts of a plastic coatings on

Process for cross-linking polypropylene, propylene copolymers, polyethylene, ethylene/propylene and ethylene/propylene/diene elastomeric copolymers and mixtures of said elastomers with above said thermoplastic polyolefins, which consists in modifying the polymer in the molten state, by the addition of 0.01%-10% by weight of carboxylic acid, possibly in the presence of a generator of radicals and by the subsequent salification with metal ions of the thus grafted carboxylic groups. The polymer products thus obtained display considerably improved characteristics under heating. In particular, there are obtained improved processability and elastic recovery characteristics for thermoplastic rubbers.

Method for improving the characteristics of polyolefins under heating

Mica-reinforced polyolefinic compositions including from 30 to 90% by weight of polyolefin, from 70 to 10% by weight of mica and from 0.01 to 7% by weight, referred to the weight of the polyolefin and of the mica, of a maleammic acid or of a maleammic silane.

Mica-reinforced polyolefin compositions comprising a maleammic silane

Glass fibers for the production of reinforced polymers, characterized in that said fibers have a coating comprising, besides a film forming agent of polyolefinic kind and a silane, also a bis-maleamic acid such as N,N'-hexamethylene-bis-maleamic acid, N,N'-dodecamethylene-bis-maleamic acid or N,N'-isophoron-bis-maleamic acid. The invention also concerns blends consisting of 50-90% by weight of a crystalline polyolefin, e.g. polypropylene and 50-10% by weight of said coated glass fibers.

Glass fibers for the reinforcement of polyolefins and reinforced

A process for promoting the adhesion of polyolefins to metals, glass sheets, cement, asbestos or polar polymers (polyamides, polyesters, ethylene-vinyl acetate copolymers, etc.), which consists in modifying the polyolefin by reaction with 0.01%-7% by weight of a compound selected from the group consisting of bis-maleamic acids, bis-fumaramic acids, alkyl esters of said acids in which the alkyl radical has from 1 to 12 carbon atoms, and precursors of said acids or esters, and successively heating at temperature at which the polyolefin is applied to the support to be coated. The main applications concern the lining of pipes or other manufactured metal articles in order to protect them against chemical and atmospheric agents.
