THERMOPLASTIC COMPOSITIONS, METHODS, APPARATUS, AND USES
Thermoplastic polyurethane (TPU) compositions, methods for producing TPU compositions, methods of using TPU compositions, and apparatuses produced therefrom are disclosed. Disclosed TPU compositions include a thermoplastic polyurethane polymer, a heat stabilizer, a flow agent, and a filler material. The filler may be a glass fiber. Disclosed TPU compositions have improved thermal stability and improved flow properties suitable for injection molding of articles of manufacture having a large plurality of fine openings or pores. Articles produced from the composition have superior thermal stability, abrasion resistance, and chemical resistance. Example articles include screening members for vibratory screening machines.
Non conductive rubber hose
A non-conductive rubber hose is provided exhibiting lower conductivity compared to conventional EPDM hose, and reduced stiffness compared to conventional non-conductive thermoplastic hose. The hose is useful for applications such as in hydraulics for boom trucks, and for coolant in plasma cutting tools.
Ethylene-vinyl alcohol copolymer composition, multilayer structure, and package
Problem to be solved: To provide an ethylene-vinyl alcohol copolymer composition which is excellent in impact resistance even without a resin other than an ethylene-vinyl alcohol copolymer blended therein. Solution to the problem: Use an ethylene-vinyl alcohol copolymer resin composition contains: (A) an ethylene-vinyl alcohol copolymer; (B) an aliphatic carboxylic acid metal salt; and (C) a sorbic acid ester; wherein the aliphatic carboxylic acid metal salt (B) contains a metal moiety selected from the group consisting of long Periodic Table 10.sup.th to 12.sup.th element metals; wherein the sorbic acid ester (C) is present in an amount of 0.0001 to 10 ppm based on the total amount of the ethylene-vinyl alcohol copolymer (A), the aliphatic carboxylic acid metal salt (B), and the sorbic acid ester (C).
THERMOPLASTIC POLYURETHANE COMPOUNDS EXHIBITING ENHANCED STAIN RESISTANCE
Thermoplastic articles are molded from thermoplastic polyurethane compounds including blends of aliphatic poly-caprolactone thermoplastic polyurethane and aromatic thermoplastic polyurethane selected from aromatic polyester thermoplastic polyurethane, aromatic polyether thermoplastic polyurethane, and combinations thereof. The thermoplastic articles exhibit enhanced stain resistance, as represented by achieving a rating of 2 or better according to Blue Jean Abrasion Test, relative to thermoplastic articles molded from thermoplastic polyurethane compounds including either aromatic polyester thermoplastic polyurethane or aromatic polyether thermoplastic only, while also having good clarity (i.e., low haze) and other desirable properties. The thermoplastic articles can be especially useful as protective cases for handheld electronic devices.
LASER ENGRAVABLE LABELS
Coextruded acrylic foils made from impact-modified polyalkyl (meth)acrylates and laser engravable labels containing these foils. The coextruded acrylic foils are designed for labelling by a laser and contain a contrast layer having at least one inorganic filler and an engraving layer arranged on the contrast layer and having at least one colourant.
Abusively molded article including UV-stable polycarbonate
A molded article includes a polycarbonate resin, an ultraviolet (UV) absorbing component, a heat stabilizer component and an acid stabilizer component. The polycarbonate resin is produced by an interfacial polymerization process and has an end-cap level of at least about 98%, and includes a ratio of bound UV absorbing component to free UV absorbing component of less than about 1.0 when molded under abusive molding conditions. The polycarbonate resin may include high purity polycarbonate. The acid stabilizer component may include a sulfonic acid ester. Methods of forming molded articles are also described.
Degradable polymer and method of production
A degradable polymer composition comprising: (a) a polyolefin; (b) two or more transition metal compounds in a total amount of from 0.15 to 0.6 wt %, (c) a mono- or poly-unsaturated C.sub.14-C.sub.24 carboxylic acid, or an ester, anhydride or amide thereof, in an amount of from 0.04 to 0.08 wt %; (d) a synthetic rubber in an amount of from 0.04 to 0.2 wt %; and, optionally: (e) dry starch in an amount of from 0 to 20 wt %; and/or (f) calcium oxide in an amount of from 0 to 1 wt %; and/or (g) a phenolic antioxidant stabilizer in an amount of from 0 to 0.2 wt %; wherein the two or more transition metal compounds are selected from iron, manganese, copper, cobalt and cerium compounds and wherein the transition metals in the two or more transition metal compounds are different.
