  • Patent number: 9991182
    Abstract: The invention relates to the use of specific organopolysilazanes as an encapsulation material for light emitting diodes (LED). The organopolysilazane polymers act as insulating filling materials and are stable over temperature and over exposure to ambient UV radiation. The encapsulating material has good thermal stability against discoloration to yellow by aging even at high temperatures which is a key factor for the long lifetime of an LED encapsulant and the LED performance.

  • Patent number: 9855688
    Abstract: The present invention provides a thermoplastic polyurethane composition for injection molding and a method of manufacturing the same. The thermoplastic polyurethane composition for injection molding can be easily injection-molded since a slip property is imparted to a soft segment, and can possess excellent durability properties such as heat-aging resistance, photoaging resistance, and wear resistance, and stability properties such as airbag deployment performance and anti-fogging property, as well as excellent tactile sensation and embossing quality, when a chain extender and a multifunctional polydimethylsiloxane-based compound are mixed with an isocyanate- and ether-containing polyester polyol, and can be useful in simplifying processes, reducing manufacturing costs, and simplifying facilities due to a decrease in the number of parts when molded articles are manufactured using the composition.

  • Patent number: 9851472
    Abstract: A hydrophilic siloxane copolymer of siloxane and hydrophilic organic monomer/s The copolymers can be functionalized to make them capable of undergoing further polymerization by thermal or actinic radiations. The hydrophilicity of these polymers can be varied by varying the siloxane versus organic monomer ratio thereby going from water dispersible to soluble states. The siloxane content can be tuned accordingly in order to provide moderate to high oxygen permeability. These copolymers can be used as a single component curable composition which results in hydrogels to minimize the presence of leachable components thus by reducing the processing cost. The polymers may also find applications in personal care formulations as copolymers, film-formers, hydrogels, coating, emulsions/latex etc.
