The invention described herein generally pertains to the use of low boiling point, low vapor pressure blowing agents with froth polyurethane or polyisocyanurate foams to fill hollow cavities (particularly window lineals) and which have lowered exotherms, which prevent deformation of the hollow cavity (e.g., window lineal) and additional achieve filling of longer lengths of window lineals by increasing the foaming and gel times of the reaction.

The invention provides polyurethane and polyisocyanurate foams and methods for the preparation thereof. More particularly, the invention relates to polyurethane and polyisocyanurate foams having an open-cell, closed-cell or a combination of open and closed cell structure, and methods for their preparation. The foams are produced with a polyol premix composition which comprises a combination of a hydrohaloolefin blowing agent, a polyol and a catalyst which is an adduct of an amine and an organic acid.

A construction board comprising (i) a foam body having a generally planar shape with first and second planar surfaces, where said foam body is a closed-cell foam body including pentane and a blowing agent additive that has a Hansen Solubility Parameter that is greater than 17 MPa.sup.0.5 contained within the foam body; and (ii) first and second facers attached to said first and second planar surfaces, respectively.

The present invention relates to a process for the production of a rigid polyurethane foam or rigid polyisocyanurate foam, comprising the reaction of at least one polyisocyanate and of a polyol composition (PZ), where the polyol composition (PZ) comprises at least one compound having at least two hydrogen atoms reactive toward isocyanate groups and at least one compound (I) selected from the group consisting of dicarboxylic diesters of dicarboxylic acids having from 2 to 18 C atoms and tricarboxylic triesters of tricarboxylic acids having from 3 to 18 C atoms, where at least one blowing agent is used during the reaction. The present invention further relates to rigid polyurethane foams or rigid polyisocyanurate foams obtainable or obtained by such a process, and also to a polyol composition (PZ) at least comprising one compound having at least two hydrogen atoms reactive toward isocyanate groups and at least one compound (I) selected from the group consisting of dicarboxylic diesters of dicarboxylic acids having from 2 to 18 C atoms and tricarboxylic triesters of tricarboxylic acids having from 3 to 18 C atoms. The present invention also relates to the use of such a polyol composition (PZ) for the production of rigid polyurethane foams or rigid polyisocyanurate foams, and also to the use of a rigid polyurethane foam or rigid polyisocyanurate foam of the invention as, or for the production of, insulation materials, preferably insulation sheets, sandwich elements, hot-water tanks, boilers, coolers, insulation foams, refrigerators or freezers.

Isocyanate-reactive compositions, polyurethane foam-forming compositions, rigid polyurethane foams, and methods for their production, and composite articles comprising such foams sandwiched between metal facer substrates. The rigid polyurethane foams are produced using a hydrochlorofluoroolefin (HCFO) physical blowing agent and can exhibit a combination of properties suitable for use in the production of discontinuous panel insulation, such as the production of insulated entry doors. The foams may exhibit thermal insulation properties similar to comparable foams suitable for use in such applications, while utilizing significantly reduced amounts of HCFO.

Methods of making thermoplastic foam comprising: immersing a plurality of thermoplastic pellets comprising at least about 50% by weight of polystyrene in a physical blowing agent bath containing from greater than about 50% by weight to less than about 90% by weight of pentane; and from greater than about 10% by weight to less than about 50% by weight of HFCO-1233zd(E) to produce a plurality of expandable pellets; and using the expandable pellets for form foam.
