A polystyrene (PS) composition for making an extruded foam, the PS composition comprising: a dried PS/alumina compound comprising a PS and an alumina additive, wherein the dried PS/alumina compound has a moisture content, measured by Coulometer, that is less than or equal to about 0.05 weight percent (wt %); and a blowing agent.

Pre-dried polystyrene/alumina compound for foam extrusion

A thermoplastic polyolefin composition and methods for its use is disclosed. The composition can include a thermoplastic polyolefin and a clarifying agent blend comprising a trisamide clarifier and sorbitol clarifier at a ratio of trisamide clarifier to sorbitol clarifier of 1:2 to 1:40 w/w.

Clarifier blends for optimum performance

A polymeric composition may include a polyolefin or styrenic polymer, a metallic acrylate salt, and an acid neutralizer.

Polymer foams

A method of forming a thermoformed article may include melt extruding polyethylene to form an extruded sheet. The rheological breadth parameter of the polyethylene may change by no more than about 5% after extrusion relative to the rheological breadth parameter of the polyethylene prior to extrusion. The extruded sheet may be thermoformed within a mold to form the thermoformed article. During thermoforming, the extruded sheet may be subjected to solid-state stretching in one or more directions. The thermoformed article may be retrieved from the mold. The polyethylene may have a rheological breadth parameter of from 0.20 to 0.40, a multimodal molecular weight distribution, a polydispersity (Mw/Mn) of from 5 to 18, a density ranging from 0.940 to 0.970 g/cc, may exhibit tensile strain-hardening, or combinations thereof.

Polyethylene for superior sheet extrusion thermoforming performance

A styrene monomer reclamation process and system is described. The styrene monomer reclamation process includes providing a waste plastic. The waste plastic includes styrenic polymers. The waste plastic is formed into polymer particles. At least a portion of the polymer particles are dissolved in a solvent to form a polymer stream. The dissolved polymer particles are depolymerized to form a styrene monomer stream.

Depolymerization of plastic materials

A polymer composition may include polyolefin having a molecular weight distribution of greater than or equal to 8 as measured by GPC and a metallic acrylate salt. The polymer composition may be characterized by one or more of: a melt flow rate of from 0.1 g/10 min to 10 g/10 min; a melt flow viscosity between 2,000 Pa&#xb7;s and 6,000 Pa&#xb7;s; a die swell of between 2 and 8; and a die swell characteristic time of between 0.3 seconds and 1.2 seconds. The polymer composition may be in the form of foam. A process of forming foam may include supplying polymer composition including metallic acrylate salt and polyolefin resin, and mixing the polymer composition with foaming agent. A foam may include a polymer composition that includes polyolefin and polar polymer and does not include an ionomer. The foam may have a foam density of less than 0.25 g/cc.

A high impact polystyrene (HIPS) is made from styrene monomer and 3 to 20 wt % of an elastomeric component phase including polybutadiene rubber and styrene butadiene copolymer. The HIPS has a 60 degree gloss of 90 or more, a Gardner drop of at least 10 in-lb, and an Izod impact strength of 1.8 ft-lb/in or more. The HIPS can have salami morphology with rubber particle size between 1 and 1.3 microns.

A suction canister liner including a one-piece liner having a generally cylindrical shape with an open end, a closed end, a sidewall connecting the open end to the closed end, and a rim extending outward generally perpendicular to the sidewall at the open end. An inner surface of the sidewall at the open end of the liner is configured to receive a lid in a sealing engagement and the rim can engage an open-ended suction canister and support the liner within the suction canister.
