Latest Patents

Hirofumi Omura holds a patent for "Interlayers for use in sound-insulating laminated glasses." This invention features an interlayer that is a laminated film composed of two types of resin films. Film (A) is a polyvinyl acetal acetalized with an aldehyde containing 6 to 10 carbon atoms, while film (B) is acetalized with an aldehyde containing 1 to 4 carbon atoms. Additionally, there is a resin film (C) that comprises a mixture of the two types of polyvinyl acetal resins. This interlayer effectively mitigates the coincidence effect, preventing the reduction of the transmission loss (TL) value without compromising the essential characteristics of laminated glasses. As a result, it exhibits outstanding sound-insulating properties over a wide temperature range for an extended period.
