  • Patent number: 10508204
    Abstract: Photo-protected microcapsules containing a photopolymer composition are dispersed in an epoxy coating to form an autonomic self-healing material. The capsule shell wall is formulated to protect the photopolymer composition from electromagnetic radiation exposure prior to rupture of the capsule shell, so that the photopolymer composition (e.g., a UV curable epoxy resin) remains active until triggered by damage to the capsule shell. Carbon black pigment is a suitable UV protector for the capsules. Upon sufficient damage to a region of the coating, the capsules will rupture and the photopolymer composition will fill and cure in and/or around the damaged region in the presence of electromagnetic radiation, achieving autonomic healing of the damaged coating.

  • Patent number: 10508184
    Abstract: The present disclosure relates to thermoplastic vulcanizate (TPV) compositions and foaming agent masterbatches suitable for foaming, as well as foamed TPV compositions, methods of making the foregoing, and applications of various foamed TPV compositions. In particular, the present disclosure provides foaming agent masterbatches having unconventionally lower loading of foaming agent in carrier polymer. The carrier polymer may advantageously comprise or be a plastomer and/or propylene-based elastomer that is also suitable for inclusion in the TPV composition, and foaming the TPV composition may include the use of relatively greater amounts of foaming agent masterbatch. The use of greater amounts of foaming agent masterbatch with lower loading may allow for superior distribution of the foaming agent in the TPV composition during foaming, leading to greater uniformity of extent of foaming (e.g., as may be shown through greater uniformity of specific gravity in the foamed TPV composition).

  • Patent number: 10500777
    Abstract: A pre-expanded hard shell thermoplastic foam pellet is made by controlling the temperature of the melt exiting a die plate in an underfluid pelletizer, and by controlling the temperature and pressures of the cooling fluid as the pellet flows from the cutting chamber through the slurry line toward a centrifugal dryer. The process and apparatus used for controlling the above parameters is described in conjunction with making the pellets. The pellets thus formed may have a generally spherical shape, or they may have odd, irregular shapes with foam hemorrhages protruding therefrom, depending on the conditions during pre-expansion.
