Polymeric aerogels, articles made from the polymeric aerogels and methods of making the polymeric aerogels are provided. The aerogels are made e.g. from crosslinkable monomers such as isocyanate monomers or phenolic monomers and a filler comprising crosslinkable hydroxyl groups. The filler may be natural (e.g. wood flour) or synthetic. The aerogels and products made therefrom exhibit low thermal conductivity and are mechanically strong. Due to their physical properties, these materials are used as e.g. building envelope components, such as walls, roofs and frames, to improve the thermal performance thereof, and may be used in a variety of other applications such as sound and insulation barriers in mechanical equipment, cryogenic containers, etc.

A polyvinyl chloride polymer (PVC) composite material is described herein. The PVC composite material includes 40-60 parts by weight of PVC, 40-60 parts by weight of calcium carbonate, 0.2-0.6 parts by weight of composite foaming agent, 3-5 parts by weight of foam regulator, 2-4 parts by weight of toughener, 0.8-1.2 parts by weight of lubricant, and 2-3 parts by weight of stabilizer. Meanwhile, the present invention provides a foam board made of the PVC composite material and flooring. The resulting PVC products have a high-strength structure and a good foaming property, bring the comfort to feet as the resilient flooring does, have a satisfied sound reduction and can be easily installed as the hard flooring could.

The present invention provides a continuous process for solid-state expansion of a biopolymer, e.g., polylactic acid, which can be used to manufacture reduced-density thermoplastic materials with improved physical and thermal properties. By incorporating multiple stages of heating into the process as a means to regulate heat flux, unprecedented control of microstructure and crystallinity can be achieved. Thermoplastic sheets with the distinct cellular characteristics implied by the process disclosed herein were found to be thicker and stronger than materials prepared by conventional processes. Thermoforming sheets with such characteristics enabled the production of light-weight thermally-stable, compostable products that resist warping, and are thus suitable for a range of industrial applications.

The invention relates to a film having a wood-like appearance and having a width from 0.1 to 6 m, a length of 2 to 10,000 m, a thickness from 180 to 1,000 m and formed from, a material which contains, relative the total weight thereof 40 to 85 wt % of vinylchloride polymerizate, 10 to 60 wt % of a powder made from vegetable components, 0 to 30 wt % of one or more inorganic filler substances, and 5 to 30 wt % of one or more additives.

A biodecomposable film material includes: a biodecomposable material which is one or more selected from the group consisting of polylactic acid, poly(butylene adipate-co-terephthalate) and poly butylene succinate and which has a mass percentage of 60-70%; a food grade agricultural waste having a diameter smaller than 50 m and a mass percentage of 10-30%; a modifier which is calcium carbonate powder or magnesium silicate salt powder and which has a diameter smaller than 8 m and a mass percentage of 7-29%; and an organic decomposing bacterium which is Bacillus amyloliquefaciens. The organic decomposing bacterium is heat resistant bacillus capable of withstanding a temperature of 100 C. and has a mass percentage of 1-3%. The biodecomposable material, the food grade agricultural waste, the modifier, and the organic decomposing bacterium are subjected to compounding and blowing to form a film having a thickness of 40-60 m.

A method of producing a hemp fiber foam is disclosed. The method may include providing a mixture of foam reactants including an amount of hemp fiber that contains an amount of absorbed moisture. The method may further include providing an amount of water to the mixture based on the amount of absorbed moisture within the amount of hemp fiber. The method may further include reacting the mixture, pouring the mixture into a mold, and curing the mixture to form a hemp fiber foam wherein the amount of hemp fiber is incorporated into the hemp fiber foam.

An exercise mat is manufactured by a method including the steps of: mixing 15 wt % to 60 wt % of a plant fiber composite and 40 wt % to 85 wt % of a foamable material to form a mixture; adding an appropriate foaming agent; and foaming the mixture at a predetermined temperature to form a mat. The plant fiber composite includes a plant fiber raw material, a starch assistant and a biopolymer additive containing a plant hormone, an enzyme, a biological vinegar, and lactic acid ester. The foamable material is one selected from polyvinylchloride (PVC) and natural rubber (NR).

A cellulosic composite includes a thermoplastic polymer matrix and from 5 up to 80 weight-% of cellulose and/or lignocellulose fibers. The cellulose and/or lignocellulose fibers include a mixture of elongated cellulose and/or lignocellulose fibers having an average elongation equal to or lower than 0.300 and rounded cellulose and/or lignocellulose fibers having an average elongation equal to or higher than 0.325.
