A method of preparing a resin infused random fiber mat including the step of forming a liquid dispersion mat of polymeric resin and fiber on a porous substrate.

Manufacture of composite dispersion based resin-infused random fiber mat

Methods for preparing waterborne heat seal coating compositions are disclosed, including (A) melt blending an ethylene vinyl acetate copolymer, a tackifier, and a wax in a first mixing apparatus to form a melt blend, (B) contacting the melt blend with an initial aqueous stream comprising a neutralizing agent, water, and a surfactant in an emulsification zone of the second mixing apparatus to form a dispersion, and (C) diluting the dispersion with water in a dilution zone of the second mixing apparatus to form the waterborne heat seal coating composition. Methods for preparing waterborne heat seal coating compositions are also disclosed, including (A) melt blending an ethylene vinyl acetate copolymer, a tackifier, and a wax in a mixing and conveying zone of a mixing apparatus to form a melt blend, (B) contacting the melt blend with an initial aqueous stream comprising a neutralizing agent, water, and a surfactant in an emulsification zone of the mixing apparatus to form a dispersion, and (C) diluting the dispersion with water in a dilution zone of the mixing apparatus to form the waterborne heat seal coating composition, wherein the length-to-diameter ratio of the extruder mixing apparatus is greater than or equal to 12 to 1. Waterborne heat seal coating compositions prepared according to the disclosed methods are also disclosed.

Methods for preparing waterborne heat seal coating compositions

A method for processing a thermoset resin mixed with inorganic fibers; said method comprising combining a thermoset resin, an inorganic fiber and water to produce a dispersion.

Continuous process for polymer/fiber molding compounds using polymer dispersions

A molding compound is made by heat-softening, fusing and compressing strips of unidirectionally aligned filaments embedded in a thermosetting resin. The thermosetting resin is non-tacky at room temperature, which allows for easy handling, elimination of cold storage and the use of robotic manufacturing methods. Composites made by molding the molding compound have excellent, highly isotropic tensile properties.

Molding compound having randomly oriented filaments and methods for making and using same

The present invention relates to method to make a spray skin from an aqueous polyolefin dispersion composition comprising a an olefin block copolymer, a dispersing agent, preferably an ethylene acrylic acid, and water, wherein said aqueous dispersion preferably has a pH less than 12 and is derived from the melt blending. The method comprises the steps of spraying the aqueous polyolefin dispersion onto a heated mold forming the skin and then allowing it to dry.

Method to make an elastomeric polyolefin skin

Method for recycling scrap that contains one or more heat resistant fibers and from 25 to 60 wt. %, based on the total weight of the scrap, of an at least partially uncured to fully uncured two component thermosetting resin mixture of (i) one or more thermosetting resins, and (ii) a solid hardener, the methods comprising shredding the scrap to an average size of from 3 to 50 mm, mixing the shredded scrap, preferably after preheating the scrap, to provide a fluid material charge and then compression molding the fluid material charge to make a cured composite material.

Process for reclaiming scrap or unused epoxy resin prepreg
