A fire retardant article has a wood-based material with a polyisocyanurate foam article attached thereto, where the polyisocyanurate foam article covers 90% or more of the exposed portion of the wood-based material, has a thickness greater than 1.8 centimeters, a foam core having a density of 28-128 kg/m, a trimer concentration characterized by at least one of (i) a trimer level in a range of 12-25 weight-percent and (ii) a molar ratio of trimer to sum of urethane and urea in a range of 1-8, a phosphorous concentration of at least 0.3 wt %, a combined concentration of phosphorous and bromine of at least 0.5 wt %, and a vapor permeable and non-combustible facer on at least one primary surface of the foam core.

Wood-based material insulated for combustion resistance

An insulated spa cover () contains a thermal insulating core (), a top cover () with an average permeance of at least 57.2 nanograms/Pascal*seconds*square meters, and a hydrostatic head test value of at least 5,000 Pascals, a vapor barrier () and optionally a bottom sheet () apart from the vapor barrier. Venting pathways are defined around the thermally insulating core to facilitate escape of water vapor.

Vented insulated spa cover

A mixing device () containing a housing () that defines a mixing chamber (), an A-component feed channel entrance opening (), a B-component feed channel entrance opening (), and air feed channel entrance opening (), and an exit opening () where the feed channel entrance openings and exit opening provide fluid communication into and/or out of the mixing chamber, and a static mixing element () housed within the mixing chamber between the three entrance feed channels and the exit opening, wherein the air feed channel entrance opening having a cross sectional area that is 0.7 square mm or greater and 7.7 square mm or less.

Mixing device for two component polyurethane foam formulation

A dispenser comprises a housing defining at least three feed channels, a spool valve with a spool defining at least three flow passages, a deformable sealing plug in at least two of the feed channels and in sealing orientation with both the housing and the spool, and a nipple in at least the two feed channels of the housing comprising sealing plugs; wherein the spool can reversibly rotate between an open orientation and a closed orientation can dispense two-component form formulations that are free of gaseous blowing agents.
