Abstract: A composition for a single-component polyurethane foam and a method of using the same. The composition comprises a polyether or polyester or a combination thereof with functionality 2 and a hydroxyl number between about 22 mgKOH/g and about 374 mgKOH/g, a polyether or polyester or a combination thereof with functionality 3 and a hydroxyl number between about 84 mgKOH/g and about 842 mgKOH/g, a fire-retarding agent, a silicone stabilizer, a catalyst, polymeric diphenylmethane diisocyanate, a dimethyl ether, propane, isobutane or a combination thereof, and 1,1-difluoroethane or any other Freon, or any combination thereof.

Abstract: A system for the application of foamable chemical compositions is presented. The application system comprises an ergonomic handle/adapter removably attachable to a pressurized source of a foam product, the handle having inlet and outlet orifices or openings for flow of the foam product from the pressurized source to a nozzle, the nozzle having an outlet orifice for dispensing the foam product and an inlet orifice for connecting to a flexible tubular connecting member which interconnects the outlet orifice of the handle/adapter with the inlet orifice of the nozzle. The nozzle of the present invention includes design features to produce a fan shaped spray pattern of the foam product and to reduce the incidence of leakage or dripping of either moisture or the foam product at the nozzle's outlet. The tubular connecting member is flexible and therefore allows a user to spray foam into hard to reach places.

Abstract: A composition for a single-component polyurethane foam and a nozzle for spraying the same. The composition comprising a polyurethane pre-polymer dissolved in liquid hydrocarbons, wherein the polyurethane pre-polymer further comprises polyethers or polyesters, wherein at least one of the polyethers or polyesters is a diol with an average functionality ƒ=2, a hydroxyl value within 35-180 mg KOH/g, and with an acid value not exceeding 0.2 mg KOH/g. The single-component polyurethane foam composition being sprayable onto a surface at a rate of 6 to 10 grams/second from the nozzle of the present invention wherein a coating depth of up to 30-55 mm is obtained over a 1 m2 surface after one minute of product application. The nozzle of the present invention comprising design features to produce a cone-shaped spray pattern of the foamable product.

Abstract: A soil reinforcement membrane that promotes grass, plant, and vegetation growth in a variety of temperatures and geographic locations and increases water retention. The soil reinforcement membrane is flexible enough to be placed on a variety of landscapes and promotes growth in a variety of soils. The soil reinforcement membrane consists of an upper layer and a lower layer with a cultivating compound dispersed uniformly between the two layers.
