Abstract: Syntactic polyurethane elastomers are made using a non-mercury catalyst. The elastomer is made from a reaction mixture containing a polymer polyol which has a liquid polyether polyol as a continuous phase and polymer particles dispersed in the liquid polyether polyol, a chain extender, a polyisocyanate and microspheres. The elastomer adheres well to itself, which makes it very useful as thermal insulation for pipelines and other structures that have a complex geometry.

Abstract: Syntactic polyurethane elastomers are made using a non-mercury catalyst. The elastomer is made from a reaction mixture containing a polyether polyol, a chain extender, a polyisocyanate and microspheres. The elastomer is characterized morphologically by the presence of small discrete morphological domains 0.1 to 3 ?m in diameter, and the substantial absence of discrete morphological domains 5 to 30 ?m in diameter. The elastomer adheres well to itself, which makes it very useful as thermal insulation for pipelines and other structures that have a complex geometry.

Abstract: A flooring coating composition includes a coating agent that is a reaction product of an epoxy based formulation, the epoxy based formulation being at least one of an epoxy prepolymer formulation, an epoxy-silane hybrid formulation, and an epoxy thiol acrylate formulation. The coating agent in a cured state exhibits a first tan delta peak between a first temperature range of 75 C to 0 C and a second tan delta peak between a second temperature range of 20 C and 75 C, according to a tan delta plot over a range of temperatures. A value of the first tan delta peak and a value of the second tan delta peak each represents a ratio of a loss modulus of the coating agent and a storage modulus of the coating agent at a specific temperature within the range of temperatures, as measured according to dynamic mechanical thermal analysis. The values of the first and the second tan delta peaks are from 0.10 to 0.80.

Abstract: Flexible polyurethane foams are made using certain hydrolysable silane compounds in the foam formulation. The hydrolysable silane compounds contain at least one isocyanate-reactive group and at least one hydrolysable silane group. The presence of the hydrolysable silane compound in the foam formulation leads to improved tensile, tear and elongation properties without an adverse effect on other important foam properties such as resiliency and hysteresis loss.

Abstract: Embodiments of the invention provide for low density flexible polyurethane foams are reaction products of reaction systems including at least one polyol and at least one isocyanate including at least 50% by weight of an MDI based isocyanate. The flexible polyurethane foam has a density of less than about 33 kg/m3 as determined according to ASTM D 3574-01, a tear strength of more than about 160 N/m as determined according to NBR 8515:2003 and a resiliency of at least 45% as measured according to ASTM D-3574-H.

Abstract: Moisture curable compositions including silylated polymers and methods for producing the same are provided. A two component moisture curable system for producing a cured or cross-linked silylated polymer having improved compression set properties is provided. The two component system comprises a first formulation and a second formulation. The first formulation comprises a silylated polymer, water, and filler and the second formulation comprises the silylated polymer, a curing catalyst comprising at least one Brønsted acid, and a moisture scavenger. The final cured formulation may have a compression set, determined by ASTM D395 or ISO 815-1, of less than 100%, and in some examples less than 50% and in some examples less than 15%. This demonstrated improvement in compression set not only allows the silylated polymers to be used in applications where cyclic loads are applied but also enhances product durability.
