Embodiments of the present invention provide systems and methods for using nonwoven materials for evacuation slides, life rafts, life vests, and other life-saving inflatable devices. The nonwoven materials have a substrate layer with continuous filaments formed in various directions.

Embodiments of the present disclosure relate generally to nonwoven substrate materials that find particular use in connection with evacuation slides, evacuation slide/rafts, life rafts, life preservers/vests, or other emergency flotation devices. Such devices are typically formed from woven substrates, but the present inventors have determined that using nonwoven substrates in connection with such devices can provide improved benefits. The nonwoven substrates further have a gas barrier formed thereon by using layer-by-layer (LBL) nanocoating technology.

The present invention relates to a process for producing an insulation component in which an insulating foam material is placed in a mold and in which (a) isocyanates, (b) polymeric compound having hydrogen atoms reactive towards isocyanate, (c) chain extenders and/or crosslinkers, and (d) catalysts are mixed to give a reaction mixture and the reaction mixture is injected into the mold and cured to form a seamless outer material enclosing the insulating foam wherein the average functionality of the polyols (b) and the chain extenders and/or crosslinkers (c) and the isocyanates (a) is greater than 2.2. The invention further relates to an insulation component obtainable by such a process and a door or wall component for cold storage that is made from that insulation component.

Mattresses and methods for processing a flexible foam material for use in a mattress to provide a mattress foam material that has more consistent firmness over time and area. The methods include pre-conditioning the foam pad or mattress by applying a force across a substantial portion of a major surface of the mattress to compress or stretch the height of the foam, the length of the foam, and/or the width of the foam to break or open closed cells. In certain embodiments, the force is applied by repeatedly pressing a platen against the foam pad or placing the foam pad between one or more rollers.

A method for manufacturing an elastic layer on site provides for downsizing an aged artificial turf into artificial turf fragments, processing the artificial turf fragments for generating a plastic melt, after the plastic melt solidifies, downsizing the solidified plastic melt into plastic particles, mixing the plastic particles with a binding agent for forming a fluid elastic composite, and applying the fluid elastic composite on a substrate at the site for forming the elastic layer.

The present invention relates to a method for producing composite components with improved interlaminar bonding, the components comprising a carrier, comprising polycarbonate and at least one polyurethane layer that is in direct contact with this carrier. The invention also relates to composite components with improved interlaminar bonding, and to the use of a polycarbonate with defined OH content as a carrier material in the production of composite components with improved interlaminar bonding.

The present invention relates to novel anisotropic composite materials and processes for production thereof. The composite materials are based on the crosslinking of polyisocyanates and feature good weathering stability.

A polyol stiffening additive in a powder bed material for three-dimensional (3D) printing is disclosed herein. In an example, the 3D powder bed material includes an elastomeric build material and a polyol stiffening additive having 3 to 7 carbon atoms that is about 2 weight percent to about 20 weight percent of a total weight of the 3D powder bed material.

A three-dimensional (3D) printed object is described. The 3D printed object comprises a polymer. A surface of the 3D printed object comprises the polymer 5 and a UV absorbing colorant. The surface has a surface area roughness Sa (arithmetical mean height) of 5.0 m. A method for preparing a three dimensional (3D) printed object having a smooth surface is also described.
