  • Patent number: 10539290
    Abstract: The invention relates to optical light diffusers for use with point light sources, such as LED lighting. The optical diffusers achieve an optimum balance of light transmission and hiding power. The optical light diffuser is a transparent plastic matrix, such as Plexiglas® resin from Arkema Inc., having organic particles dispersed within the matrix. The particles are crosslinked beads having specific particle sizes and loading. Different beads can be combined to provide added properties such as a textured surface, and to optimize hiding power and light transmission. The invention also relates to a luminous device containing at least one light-emitting diode and a cover made of the optical light diffuser. The invention further relates to a method for assessing hiding power.

  • Patent number: 8404755
    Abstract: Polyester compositions described herein have properties which are particularly suitable for extrusion blow molding (EBM). These properties relate primarily to the rate of crystallization and melt strength or melt viscosity. Articles prepared from the polyester compositions exhibit good clarity, aesthetics, and other physical properties. The polyester compositions also exhibit broad molecular weight distribution (MWD), resulting in improved processability and melt strength. The crystallization rate allows for good drying characteristics while also enabling the use of regrind. In addition, the compositions exhibit improved recyclability, such as in existing PET recycling streams. In one aspect, articles are prepared in an extrusion blow molding method by combining a dry first polyester copolymer component, a dry second polyester component, and a chain extender to form a feed material suitable for extrusion blow molding.
