  • Publication number: 20230249423
    Abstract: A method for modifying optical properties of a synthetic resin increases a transmittance by modifying, removing, or reducing factors which absorb wavelengths in an ultraviolet range, such that it is possible to maintain stable and excellent reliability even after a long-term use. In a method for modifying optical properties of a synthetic resin, a modification treatment which is an energy irradiation treatment is performed on a cured product made of a synthetic resin to increase a transmittance in an ultraviolet range. For example, the modification treatment which is at least one of a photo-oxidation treatment and a thermal oxidation treatment is performed on the cured product made of the synthetic resin to increase the transmittance.

  • Patent number: 11472945
    Abstract: A slidable rubber material that has an amino-modified interfacial layer that does not affect the compression set. Although the slidable rubber material includes a rubber component such as a butyl rubber or halogenated butyl rubber etc. having the low-compression set, which contains a vulcanization agent such as a nitrogen/sulfur compound or a vulcanizing auxiliary agent, the rubber part is coated with a silicone rubber layer. The slidable rubber material exhibits a slidability and resists the detachment or elution of fine particles from the coating layer. A rubber component and a vulcanization agent; an interfacial modification layer that coats the rubber part and an amino-modified silicone compound is incorporated with surface molecules of the rubber part; and a layer that coats the interfacial modification and contains solid fine particles, an addition-type or condensation-type silicone rubber in which the particles are dispersed, and a curing catalyst for silicone rubber.

  • Patent number: 11326065
    Abstract: A versatile silicone resin reflective substrate which exhibits high reflectance of high luminance light from an LED light source over a wide wavelength from short wavelengths of approximately 340-500 nm, which include wavelengths from 380-400 nm near lower limit of the visible region, to longer wavelength in the infra-red region. The silicone resin reflective substrate has a reflective layer which contains a white inorganic filler powder dispersed in a three-dimensional cross linked silicone resin, the inorganic filler powder having a high reflective index than the silicone resin. The reflective layer is formed on a support body as a film, a solid, or a sheet. The silicone resin reflective substrate can be easily formed as a wiring substrate, a packaging case or the like, and can be manufactured at low cost and a high rate of production.
