  • Publication number: 20220169834
    Abstract: The present invention describes thermoplastic vulcanizates (TPVs) and methods for forming TPVs that include addition of a masterbatch comprising antioxidant (AO) additives to improve UV weatherability of TPVs. The hindered phenol antioxidants have a melting point of 85° C. or less, and comprise an alkyl chain longer than 12 carbons. A method may comprise compounding a carbon black, carrier resin, and hindered phenol antioxidant to form a masterbatch and dynamically vulcanizing the masterbatch, a vulcanizable elastomer, a thermoplastic resin, and a process oil to yield a TPV.

  • Patent number: 5056893
    Abstract: A display device which includes a matrix array of rectangular liquid crystal display elements on a base, all of the display elements of the array having a same height. The matrix array is arranged in rows and columns with uniform gaps between the columns. The base has lateral edges spaced from the outer columns for abutting lateral edges of other display devices. The display elements of the middle columns between the outer columns all have a same width. In order to maintain the same periodicity between the adjacent outside columns of adjacent display devices as is present between the columns within each display device, the display elements of the outer columns have a smaller width than the width of the display elements of the middle columns so as to compensate for enlarged distances between the outside columns and the lateral edges.
