  • Patent number: 6855758
    Abstract: The invention relates to transparent, biaxially oriented and heat-set films having one or more layers and compris, as main constituent, at least one crystallizable thermoplastic, in particular a polyester, and also comprise at least one hydrolysis stabilizer. The hydrolysis stabilizer is preferably a phenolic compound, an oxazoline, and/or a monomeric or polymeric carbodiimide, where appropriate combined with an organic phosphite. It is preferably added in the form of a masterbatch. The film exhibits low longitudinal and transverse shrinkage. On exposure to moisture and heat it shows practically no embrittlement and retains its ultimate tensile strength. The additional functionality is preferably that the film has been made UV-resistant, or flame-retardant, or on one side or on both sides has been coated, or is sealable, and/or has been corona- or flame-treated.

  • Patent number: 6806304
    Abstract: The present invention relates to a process for improving the shelf life of a hindered phenol antioxidant comprising the step of intimately mixing the hindered phenol antioxidant with a sulfur-containing peroxide decomposer. The inventors have discovered that mixing the peroxide decomposer with the hindered phenol antioxidant reduces the tendency of hindered phenols to yellow with age. This increases the desirability of the hindered phenol because it will not impart color to polymer systems. The present invention also relates to a composition produced from the process described above, and stabilized compositions and additive packages containing the composition produced from the above-described process.

  • Publication number: 20040176512
    Abstract: The invention is the manipulation of the zinc oxide content and sulfur content of nitrile butadiene rubbers and selected vulcanization conditions that can be achieved economically with common production facilities. The manipulation of these components affects the relaxation property of gloves formed by this material. Produced are gloves that have a relaxation property, higher than 50%, and a low modulus (approximately 3 Mpa). The glove maintains decent ultimate tensile strength (>20 Mpa) and elongation (>500%). The glove is produced by a vulcanization process, which lasts from 5 to 60 minutes at temperatures ranging from 300° F. to 400° F. The tensile strength and elongation are well above the ASTM requirements for medical gloves. The current ASTM requirements are ASTM D412-92. Thanks to sufficient vulcanization, the films produced provide satisfactory protection from viral penetration. The tearing strength is also better because of the lower modulus.
