The present invention relates to a method for producing a molded body by the selective laser sintering of a sinter powder (SP). The sinter powder (SP) contains at least one polyamide (P) and 5 to 50 wt %, preferably 10 to 50 wt %, of at least one aluminum silicate. The at least one aluminum silicate has a D50 value in the range of 2.5 to 4.5 μm. The present invention also relates to molded bodies obtainable by means of the method according to the invention.

Provided is a method for producing a decorated cycloolefin resin molded article, the method comprising curing a gel coat composition and polymerizing a cycloolefin polymerizable composition containing a radical generator while the gel coat composition is in contact with the cycloolefin polymerizable composition, thereby containing a decorated cycloolefin resin molded article including a gel coat and a cycloolefin resin layer adhering to each other.

A method of producing a reinforcing bar (rebar) includes: arranging one or more thermoplastic polymer fibers (2) in a central portion of a cross-section; arranging a plurality of non-metallic reinforcing fibers (1) on an outer periphery of the thermoplastic polymer fiber(s) (2); heating the thermoplastic polymer fiber(s) (2) to its (their) melting temperature or higher to melt the thermoplastic polymer fiber(s) (2); and cooling the melted thermoplastic polymer to form a bar-shaped polymer layer (91) in the central portion of the cross-section and a fiber-reinforced polymer layer (92) on an outer periphery of the bar-shaped polymer layer (91).

A composite core material and methods for making same are disclosed herein. The composite core material comprises mineral filler discontinuous portions disposed in a continuous encapsulating resin. Further, the method for forming a composite core material comprises the steps of forming a mixture comprising mineral filler, an encapsulating prepolymer, and a polymerization catalyst; disposing the mixture onto a moving belt; and polymerizing said encapsulating prepolymer to form a composite core material comprising mineral filler discontinuous portions disposed in a continuous encapsulating resin.

The present invention relates to a process for producing a shaped body by selective laser sintering of a sinter powder (SP). The sinter powder (SP) comprises at least one polyimide (P) and in the range from 10% to 50% by weight of at least one aluminosilicate. The at least one aluminosilicate has a D50 in the range from 2.5 to 4.5 μm. The present invention further relates to shaped bodies obtainable by the process of the invention.

A fiber product is described which includes fibers, a binder and a temperature control additive. The fiber product has properties that make it useful for a variety of applications. The fibers may be glass fibers and the product may be a fiberglass insulation product for use in buildings, vehicles, or other structures for acoustic and/or thermal insulation. The fibers may be cellulosic fibers and the product may be a wood board product. The temperature control additive is incorporated into the uncured fiber product to prevent deleterious self-heating during or after binder curing. The temperature control additive undergoes an endothermic process that consumes at least a portion of the energy generated during the exothermic curing reaction.

The present invention concerns a method of producing a moulded mineral wool insulation product, said method comprising the steps of providing a mixture by mixing mineral fibres with a binder composition, and providing said mixture in a mould form, and then curing the binder, wherein the binder composition comprises at least one hydrocolloid, and then removing the moulded product from the mould form.
