A coupling agent formulation for cellulosic material-polymer composites is provided. The formulation includes a) at least one organic peroxide; and b) at least one of i) at least one zinc-containing reagent; and/or ii) at least one silicon-containing reagent. The coupling agent formulations produce polymer matrix cellulosic material composites with improved strength and aging characteristics.

A method for producing products made of composite material, including the following operating steps: placing between a first mould and at least a second mould at least one layer of composite material fibre fabric and at least a first layer of composite material fibres, wherein a layer of non-polymerized, composite material resin, substantially free of hardener, is placed between the fabric layer and the first mould; injecting resin and hardener between the first mould and the second mould to impregnate the layer and the first fibre layer with the injected resin and polymerizing the injected resin and the resin layer with the injected hardener. A semi-finished item which can be used in this method and to a product made using this method and/or with this semi-finished item.

There is provided a polyolefin resin foam sheet having a plurality of cells which is formed by foaming a polyolefin resin, wherein, in the polyolefin resin foam sheet, the average cell sizes and the maximum cell sizes in the MD direction and the TD direction are each a predetermined value, and a ratio [TD strength at break/MD average cell size] and a ratio [MD strength at break/TD average cell size] are both 80 kPa/μm or more.

A process includes contacting a metallic acrylic salt with a polyolefin, forming a polyolefin composition. The process includes extruding the polyolefin composition, and pelletizing the extruded polyolefin composition. A production rate of pellets of the polyolefin composition may be equal to or greater than a production rate of pellets of the polyolefin prior to contact with the metallic acrylic salt without increasing extrusion pressure or motor amperes. The polyolefin composition may have a melt flow rate that is lower than the melt flow rate of the polyolefin prior to contact with the metallic acrylic salt. The metallic acrylic salt may only be contacted with the polyolefin to form the polyolefin composition during a start-up of an extruder and pelletizer.

A process for manufacturing a composite automobile part by overmoulding, over at least one surface of an insert (1) comprising a first plastic material, a layer of a second thermoplastic material, comprises the following successive steps: a) a step of positioning said insert (1) in a mould, and b) a step of moulding said second thermoplastic material over said insert. At least one of said first and second materials comprises an additive, said additive comprising a polymer to which carboxylic anhydride monomers are grafted. Said first and second materials are respectively based on polyamide and based on polypropylene, or vice versa and said second material comprises talc as mineral filler.

A multilayer film having Machine Direction Orientation (MDO) is prepared by first co-extruding a multilayer film, then stretching the multilayer film in the machine direction at a temperature lower than the melting point of the polyethylene resin that is used to prepare the film. At least one layer of the film is a first polyethylene composition having a density of from about 0.94 to about 0.97 g/cc and at least one second layer is prepared from a polyethylene composition having a lower density than the first polyethylene composition. This disclosure enables the manufacture of films having outstanding barrier properties (low Water Vapor Transmission Rate, WVTR, and low Oxygen Transmission Rate, OTR) and good physical properties.

An apparatus and process to maintain control of the temperature of low-melting compounds, high melt flow polymers, and thermally sensitive materials for the pelletization of such materials. The addition of a cooling extruder, and a second melt cooler if desired, in advance of the die plate provides for regulation of the thermal, shear, and rheological characteristics of narrow melting-range materials and polymeric mixtures, formulations, dispersions or solutions. The apparatus and process can then be highly regulated to produce consistent, uniform pellets of low moisture content for these otherwise difficult materials to pelletize.

A method of producing a directly blow-formed container. The method includes subjecting a multilayered parison having an inner surface formed of an olefin resin to direct blow forming, the olefin resin containing (i) an organic bleeding lubricant having a melting point of not higher than 50° C. in an amount of 5 to 10% by mass, and (ii) a high silica zeolite having a silica/alumina mole ratio of not less than 80 in an amount of 0.2 to 3.0% by mass.
