Systems, components, and methods for low pressure delivery of plural component foam systems comprising solid particles from unpressurized supply sources

Various examples are provided related to polyurethane spray foam and its application. In one example, a method includes providing a system including a polyurethane spray foam (SPF) raw material supply, a fluid handling system, an air source, a heated hose, a whip hose, and a metal stray gun. Each of part A and part B material streams, either or both of which include particles, are generated by the system and conveyed by the system through the system and into a disposable mixing nozzle engaged with the metal stray gun. A mixture of the part A and part B material streams can be applied, via the disposable mixing nozzle, to a surface or into a mold at a pressure of 250 psi or less. A polyurethane spray foam coating generated from the method can be applied at a thickness of from about 0.5 inches to about 12 inches.

METHOD FOR MAKING FAUX WOOD MATERIAL WITH MULTILAYER PATTERN EFFECT AND MIXED PLASTIC MATERIAL FOR USE IN THE METHOD

A method for making a faux wood material with a multilayer pattern effect and a mixed plastic material for use in the method involve: performing a compounding process on a thermoplastic elastomer material, a hard-segment-structure material and a foaming agent to form the mixed plastic material; performing through an extruder a first foaming process on the mixed plastic material to form a preliminary sheet having a density equal to 10% to 20% of the density of the mixed plastic material and a thickness of 1-4 mm; stacking preliminary sheets up; and performing through a hot-pressing mold a second foaming process on the stacked preliminary sheets to form the faux wood material having a density equal to 40%-50% of the density of the mixed plastic material. Accordingly, through the two foaming processes, a multilayer pattern effect can be presented on the faux wood material due to its density difference.
