  • Patent number: 8003720
    Abstract: Chemical additives disclosed for reducing “plate-out” which have applications in polymers, such as polyolefins. It is possible to provide for a composition and a process for producing parts, sheet and film from polyolefin extrusion applications wherein the polyolefins are processed with a minimal quantity of “plate-out.” A polyolefin composition may contain a sorbitol-based clarifying system of a derivative of Dibenzylidene, along with one or more co-additives to achieve a reduction in undesirable plate-out.

  • Publication number: 20100030170
    Abstract: This disclosure relates to a substrate comprising multiple layers which are designed to provide moisture absorption, non-adherence, and antimicrobial properties to a contact surface. The substrate is minimally comprised of (a) at least one skin contact layer of apertured hydrophobic polymeric film, (b) at least one layer of absorptive material that contains a reinforcement material, and (c) at least one layer of liquid impermeable film backing. The substrate may also include a layer of material that contains an antimicrobial agent. The substrate may be ideally suited for use in the medical field as an absorptive pad for end-uses such as wound care (e.g. burn care), surgery care, and incontinence care.
