Publication number: 20140275307Abstract: Powdered polyurethane flexible foams, preferably powdered recycled polyurethane flexible foams are used with a redispersible polymer powder (RDP), preferably as a preblended additive, in hydraulic binders or cementitious compositions to improve performance of cementitious compositions or mortar, in applications such as cement based tile adhesives (CBTA), or external thermal insulating composite systems (ETICS). The use of the powdered polyurethane flexible foam as a partial replacement for an RDP unexpectedly provides an increase in wet mortar density while maintaining excellent workability and quick open time, quicker setting times, improved impact resistance, and increased adhesion after water immersion.Type: ApplicationFiled: October 24, 2012Publication date: September 18, 2014Inventors: Juergen Dombrowski, Hartmut Kuehn, Margarita Perello, Sonja Scharlemann

Publication number: 20140275306Abstract: Pellets, beads, particles, or other pieces of a thermoplastic elastomer having a maximum size in at least one dimension of 10 mm or less (collectively, “pellets”) are infused with a supercritical fluid in a pressurized container, then rapidly depressurized and heated either by immersion in a heated fluid or with infrared or microwave radiation to foam the pellets The pellets are prepared with at least two different densities. Pellets with different densities, thermoplastic elastomer compositions, or foam response rates are placed in different areas of a mold. The mold is filled with pellets, then the pellets are molded into a part. The part has areas of different density as a result of the placement of pellets of different density.Type: ApplicationFiled: March 15, 2013Publication date: September 18, 2014Inventors: Richard L.

Publication number: 20140249242Abstract: The present invention relates to a novel type of grafting or crosslinking method for (meth)acrylates in which the reaction is initiated by isocyanates and specific bases having an imine structure. Using this novel and specifically applicable method, polymers, particularly polyolefins having double bonds, may be grafted or crosslinked in a suitable reaction procedure. Furthermore, these unsaturated polymers may be used, following reaction with (poly)isocyanates, to prepare graft or block copolymers or also for the bonding of the modified unsaturated polyolefins to polyamides, polyesters, polycarbonates, polyimines or polyurethanes.Type: ApplicationFiled: August 24, 2012Publication date: September 4, 2014Applicant: Evonik Degussa GmbHInventors: Friedrich Georg Schmidt, Stefan Spange, Ingmar Polenz

Publication number: 20140193630Abstract: Multi-component materials are substantially homogeneous and fully curable and comprise an elastic filler, an isocyanate curing agent, and a polyol resin ingredient that when combined produce a polymeric matrix, polyurethane and/or polyurea, having the filler dispersed therein. The material has a variation in polyisocyanate weight ratio of up to 350%. The filler is ground rubber tire particles sized 20 mesh or smaller. The mix weight ratio of the curing agent to resin ingredient is from about 40:100 to 140:100. The material is made and dispensed using a system configured to combine a heated mixture of the resin and filler with the curing agent at a desired variable mix ratio. A controller is used to provide the desired mix ratio and permits “on the fly” adjustment of the mix ratio while the resin and curing agent is being dispensed.Type: ApplicationFiled: July 21, 2011Publication date: July 10, 2014Applicant: RHINO LININGS CORPORATIONInventors: Russell Lewis, Mihai Solomon
