Abstract:
The essence of the technical solution lies in the fact that the composite contains from 58,5 to 88,5 weight % of polypropylene, from 10 to 40 weight % of natural fibres of cellulose (the length of the fibres from 0,2 to 2 mm) and from 1 to 1,5 weight % of silicon-based additive and from 0,1 to 0,5 weight % of additive based on dialkyl peroxides, which acts as a chemical catalyst. The obtained composite is supplied in the form of granules and is designed for a wide range of technologies for processing of plastics, for example injection.
Abstract:
Invention relates to a multilayer article comprising successively: a non-woven layer of fibers (3) comprising at least 50% by weight of at least one biodegradable polymer melting point of which is below 220°C; a layer of food-safe adhesive (2); a cellulose-fiber based support (1 ).
Abstract:
The present invention provides a fiber-reinforced resin composition, which provides a molded article having a good mechanical strength. The fiber-reinforced resin composition contains a resin-adhered long fiber bundle including (A) a thermoplastic resin and (B) a rayon fiber, wherein the rayon fiber of the component (B) satisfies the following requirements (b1), (b2) and (b3), and the resin-adhered long fiber bundle is obtained by adhering and integrating the thermoplastic resin of the component (A) in a molten state to and with a strand of longitudinally-arranged rayon fibers of the component (B), and cutting the strand into a length of 3 to 30 mm, (b1) a fiber diameter of 5 to 30 μm; (b2) a tensile elongation of 10% or more; and (b3) a flat shape with a ratio between a major axis length and a minor axis length (major axis length/minor axis length) in a width-directional cross section of 1.1 or more.
Abstract:
A process of manual, semi-automatic and fully-automated integration of discrete components into a container that results in fast, reliable, cost-effective, and scalable production of composite containers is disclosed. The process can be embodied in manufacturing equipment that has a series of stations and may be called an assembly device. The equipment can produce containers, tubs, canisters, cartridges, etc. which are easily separated into different bio-degradable or compostable parts. Other container types are possible and are contemplated.
Abstract:
The invention relates to reinforced epoxy nanocomposites, for example, cellulose nanocrystal (CNC)/epoxy nanocomposites, and methods for preparation thereof.
