This invention is concerning a structure body containing inorganic particles having an average particle diameter of 6 mm to 50 mm, and 6 parts by mass to 40 parts by mass of a resin with respect to 100 parts by mass of the inorganic particles.

A rock bag and method of manufacturing same are provided herein. In one embodiment, the rock bag has a first set of opposed sides, each side of which is substantially the same dimensions, a second set of opposed sides, each side of which is substantially the same dimensions, and a bottom side formed to operatively couple with the first and second set of opposed sides such that the rock bag forms an enclosure with five sides and an opening opposite the bottom side. And the material forming the sides comprises between 40% and 90% rock content.

A method for the manufacture and decoration of a mineral-filled resin shower tray with an external coating, including the steps of applying an external coating layer on the internal surface of a mould, casting a mix of resin and mineral filler on the mould, curing and drying the mix, and including the prior steps of disposing on the internal surface of the mould cavity a transfer film including on one of the sides thereof a pattern printed in ink, vacuum thermoforming the transfer film against the internal surface of the mould cavity, and the subsequent step of removing the film from the surface of the mineral-filled resin shower tray with an external coating.

In the method for manufacturing conglomerate stone slabs using the Bretonstone technology, in the variant where the starting mixture is enclosed between two paper sheets, the improvement consists in replacing each paper sheet with a containment element consisting of a paper sheet, one surface of which has, applied thereon, a film of plastic material which is impermeable to organic vapours, impermeable to the liquids and in particular to the liquid resin constituting the binder of said mixture, resistant to the catalysis temperatures of the said resin and resistant to hot solvents and chemical vapours. Preferably, said plastic material is water-soluble, in particular polyvinyl alcohol.

A polyvinyl halide compound, alone or alloyed with thermoplastic polyurethane, is used as a flexible layer for over-molding a rigid polymer substrate. Selection of types and amounts of calcium carbonate for the overmolding layer improves peel strength to achieve cohesive failure of the flexible overmolding layer rather than adhesive failure of the interface between the flexible overmolding layer and the rigid polymer substrate.

Provided a method for manufacturing an abrasion- and water-resistant multilayer panel, in particular an abrasion- and water-resistant flooring panel, including the steps: providing at least one plastic carrier plate, in particular a PVC carrier plate; applying at least one decorative layer to the at least one plastic carrier plate; applying at least one primer layer to the at least one decorative layer; and uniformly scattering abrasion-resistant particles onto the at least one primer layer applied to the decorative layer applying at least one cover layer.

A joining material for laser welding, a laser welding method using the same, and a laser joined body using the laser welding method. The joining material includes a polymer matrix and a needle-shaped inorganic filler. The polymer matrix includes a polypropylene resin having a melt index of 80 g/10 min or more to 95 g/10 min or less as measured at a temperature of 230° C. and a load of 2.16 kg, and the needle-shaped organic filler has an aspect ratio of 10:1 to 20:1.

Laser weldable compositions are provided which in various examples include a tricyclodecane dimethanol-modified copolymer, a terephthalate-type polyester and an inorganic filler. Compared with compositions without the tricyclodecane dimethanol-modified copolymer, the compositions of the invention have improved, uniform laser transmittance, thereby welded products including the compositions have improved bonding strength and require stronger tensile strength to be torn apart.

A plastic form and its manufacturing process are disclosed. The process involves a single-screw extruder and a twin-screw extruder in mixing a first material and a second material, and a hydraulic distributor evenly distributing the first and second materials to a mesh forming machine to produce the plastic form. The plastic form has a mesh structure by a first piece, a second piece, multiple first partitions, at least a second partition, multiple channels. The first and second materials respectively include at least one of PP particles, PE particles, PC particles, PA particles, ABS resin particles, fiberglass particles, and stone powder, in accordance with application requirement. The plastic form has advantages such as high structural strength, impact resistance, adhesion, hardness, anti-skidding, and flame retarding. As recycled materials are used, the plastic form is also inexpensive and environmentally friendly.

A monolithic thermocasting system for thermocasting polymer and solid material and method of use having an internal frame system; an external frame system disposed external to the internal frame system; a mold cavity formed between the internal frame system and the external frame system, the mold cavity sized to receive the polymer and solid material and shaped to form an architectural member; a duct; and a heater element disposed in the duct for outputting thermal energy to the mold cavity to heat the polymer and solid material, the thermal energy being sufficient to thermocast the polymer and solid material to a combined building material.
