摘要:
A reflective material comprising a multilayered array of particles encapsulated by a matrix material, the reflective material defining a primary surface, the reflective material exhibiting: (i) visible retroreflection of incident radiation, wherein a wavelength of visible retroreflected radiation decreases from a first visible wavelength at a first angle to the primary surface to a second, shorter wavelength of visible retroreflected radiation as the viewing angle to the primary surface increases; and (ii) Bragg diffraction of the incident radiation, wherein the wavelength of radiation Bragg diffracted normal to the primary surface is longer than the wavelength of visible radiation, such that no visible radiation is retroreflected or Bragg diffracted in a direction normal to the primary surface.

Shrinkable film layers having a blend of (i) one or more polymers with a high glass transition temperature, and (ii) one or more polymers with a low glass transition temperature are disclosed. Methods for preparing such film layers are also disclosed.
摘要:
A process for reducing the content of polar organic residues in mixtures of plastics from durable goods comprising separating a feed stream into two or more mixtures of flakes, each mixture containing a primary plastic type, one or more additional plastic types, at least one organic substance absorbed into the one or more plastic types, and at least one or more non-melting contaminants; and melt compounding at least one of the mixtures of flakes with calcium oxide.
摘要:
Bio-based glacial acrylic acid, produced from hydroxypropionic acid, hydroxypropionic acid derivatives, or mixtures thereof and having impurities of hydroxypropionic acid, hydroxypropionic acid derivatives, or mixtures thereof, is polymerized to poly(acrylic acid) or superabsorbent polymer using the same processes as petroleum-derived glacial acrylic acid.
摘要:
A monoaxially oriented film including a propylene-based random copolymer and at least about 3 wt% of a low density polyethylene which is oriented at least about 2.5 times in one direction and exhibits excellent linear directional tear properties parallel to the orientation direction and excellent heat seal performance in terms of high heat seal strengths and low seal initiation temperature. This film formulation and orientation is suitable for pouch applications requiring an "easy-tear" linear tear feature and excellent hermetic seal properties.
摘要:
An anti-fog coating composition is described comprising an aqueous polymeric dispersion; a crosslinker, and a surfactant. The dried and cured coating composition does not exhibit fogging within 8 seconds after being soaked in 25°C water for 1 hour. In favored embodiments, the dried and cured coating composition does not exhibit fogging within 60 seconds after being soaked in 50°C water for 24 hours. Also described are articles comprising the dried and cured coating composition disposed on a substrate as well as a method a providing an anti-fog coating on a substrate.
摘要:
The present disclosure relates to an electronic device, and more particularly, to an electronic device with laminated structure and a manufacturing method thereof. The electronic device comprises: a first substrate; a second substrate; and a solid-state adhesive layer, wherein the adhesive layer is disposed between the first substrate and the second substrate. The solid-state adhesive layer reacts with the first substrate and the second substrate to form a chemically linked chain for bonding the first substrate and the second substrate. The present disclosure further selects a solid-state adhesive with both physical and chemical cohesiveness to laminate the two substrates; thereby making an electronic device more firm with higher shock resistance.
