The present invention discloses a composition that may be extruded or injection moulded, comprising a chemically modified hardwood lignin and a polyester. The chemically modified hardwood lignin constitutes 10 to 50 weight-% of the total weight of the composition.

The invention relates to an injection-molding composition comprising at least one polyolefin, at least one delignified wood pulp fiber, at least one maleic anhydride-grafted polyolefin and at least one metal oxide chosen from oxides of alkaline earth metals or of zinc.

An object of the present invention is to provide a golf club grip having high tensile strength in the outer layer and little entrainment of air between the outer layer and the inner layer. The present invention provides a golf club grip comprising a cylindrical portion composed of a cylindrical inner layer and a cylindrical outer layer covering the inner layer, wherein a ratio (E′.sub.23/E′.sub.60) of a storage modulus (E′.sub.23) at 23° C. of the outer layer to a storage modulus (E′.sub.60) at 60° C. of the outer layer, measured with a dynamic viscoelasticity measuring apparatus under measuring conditions of an oscillation frequency: 10 Hz, a strain amplitude: 0.05%, and a tensile mode, ranges from 1.20 to 1.32.

The invention relates to a cellulose-reinforced polypropylene resin composite material, a preparation method therefor and use thereof. The cellulose-reinforced polypropylene resin composite material comprises, relative to the total weight of the composite material: 65 wt % to 85 wt % of polypropylene resin; 10 wt % to 20 wt % of a cellulose filler; and 1 wt % to 10 wt % of dyed rayon, wherein the color of the dyed rayon is different from that of the polypropylene resin. The cellulose-reinforced polypropylene resin composite material of the invention is environmentally friendly and simple to process, and has a simple molding process. The article prepared therefrom has excellent physical and chemical properties, uniform matte appearance and two-color effect.

The present invention relates to a sizing composition for mineral fibers, especially glass fibers or rock fibers, containing a liquid phenolic resin having a free formaldehyde content, expressed with respect to the total weight of liquid, of 0.1% or less and an extender.

Preferably, the liquid phenolic resin is mainly composed of phenol-formaldehyde and phenol-formaldehyde-amine condensates and has a water dilutability, at 20° C., at least equal to 1000%.

Another subject of the present invention is the insulating products based on mineral fibers treated by said sizing composition.

A bioplastic composition may contain certain biodegradable and renewable components. In some examples, the bioplastic composition includes at least one kind of aquatic macrophyte biomass, which may contain a native composition of protein and carbohydrates, in a blend with one or more types of biodegradable or durable thermoplastic polymers. The aquatic macrophyte composition may provide a balance of both polymeric and reinforcing properties to the blended bioplastic not typically exhibited by terrestrial feedstock such as soy meal or corn starch. Such a bioplastic composition may be formed into molded articles using extrusion, injection molding, compression molding, or the like.
