摘要:
A data storage medium includes a haze-prevention layer between a heat-resistant thermoplastic substrate and a reflective metal layer. The haze-prevention layer includes a metal having a tensile modulus of at least about 15×106 pounds per square inch. The data storage medium resists hazing of the reflective layer at elevated temperatures.

A reflective article useful, for example, in automotive headlights includes a haze-prevention layer between a heat-resistant thermoplastic substrate and a reflective metal layer. The haze-prevention layer includes a metal having a tensile modulus of at least about 15×106 pounds per square inch. The article resists hazing of the reflective layer at elevated temperatures.
摘要:
A data storage medium includes a substrate, a reflective metal layer, and a haze-prevention layer between the substrate and the reflective metal layer. The substrate includes an amorphous thermoplastic resin having a heat distortion temperature of at least about 140° C., a density less than 1.7 grams per milliliter, and an organic volatiles content less than 1,000 parts per million measured according to ASTM D4526. The haze-prevention layer includes a material having a volume resistivity of at least 1×10−4 ohm-centimeters and a tensile modulus of at least about 3×105 pounds per square inch. The data storage medium resists hazing of the reflective layer at elevated temperatures.

摘要:
Thermoplastic compositions comprising polyamide, polyimide, an organo phosphorus compound and an optional reinforcing filler are described. The subject compositions are useful in blow molding methods. A method of blow molding is also described as well as articles made by the method.
摘要:
The invention relates to a thermoplastic resin with improved impact strength comprising a) a thermoplastic polyether sulfone resin and b) glass fibers treated with a polyolefin wax. The polyolefin wax may be polyethylene wax, polypropylene wax, polyethylene-propylene wax, or polyethylene-butylene wax. The polyethersulfone resin glass blend has high modulus and improved impact strength.
摘要:
A molded article suitable for direct application of a reflective metal coating includes an amorphous thermoplastic or thermoplastic blend having a glass transition temperature greater than about 170° C. and at least one thermally stable colorant that contributes to the article's dark appearance. The article has excellent dimensional stability, and the surface to which a metal coating can be applied exhibits low gloss. Application of a metal coating to the molded article produces a metalized surface with high total reflectivity, low diffuse reflectivity, and low haze. Compositions and methods for forming the article are described.
摘要:
Disclosed is an article for the optical storage of data having low birefringence prepared from a mixture of a polycarbonate and a cycloaliphatic polyester. The article may optionally have stabilization and mold release additives that retain transparency, color and processability.
