    Toughness and morphology of radiation-crosslinked natural rubber modified polystyrene
    (2003-01-01) P. Aiamsen; U. Paiphansiri; S. Sangribsub; D. Polpanich; P. Tangboriboonrat; Mahidol University
    with that of unmodified PS. The impact resistance of HIPS based on RVNR was further enhanced by addition of 10% of polystyrene-block-polyisoprene-block-polystyrene copolymer. A mesh structure of all crosslinked rubber particles containing polystyrene and long crazes...γ-Radiation vulcanized natural rubber (RVNR)/phase transfer/suspension polymerization technique was used to prepare high-impact polystyrene (HIPS) in bead form. The high notched Izod impact resistance of HIPS based on RVNR was observed and compared

    Green productivity and value chain analysis to enhance sustainability throughout the passenger car tire supply chain in Thailand
    (2023-09-01) Buadit T.; Ussawarujikulchai A.; Suchiva K.; Papong S.; Rattanapan C.; Mahidol University
    and smoke sheet rubber. Cup lump and STR20 block rubber, in contrast, offered the lowest GP. Overuse of chemical fertilizer in the cup lump production, water consumption in the STR20 production and steam consumption in the tire manufacturing process were key... issues selected for developing CT options from value chain analysis. The chosen options are to fertilize following the Rubber Research Institute recommendations, recycle used or treated water in the rubber industry and lower mold open time among tire

    Hollow natural rubber latex particles as bio-based alternative white pigment for coating applications
    (2022-11-15) Promlok D.; Sonongbua K.; Wilepsuwan M.; Suteewong T.; Tangboriboonrat P.; Mahidol University
    Due to the broad particle size distribution as well as non-spherical shape of natural rubber (NR) latex particles, the non-collapse hollow NR latex particles (HL-NRPs) with well-defined void structure were developed aiming to use as an eco-friendly... acid for non-rubber substances. Since the multiple light scattering inside the hollow structure could enhance their refractive index, the optical performance of HL-NRPs as a low-density opacifying agent in poly(vinyl alcohol) matrix, was examined using

    Effects of vitamin E on the development of cholangiocarcinoma induced by combined nitrite and aminopyrine
    (Mahidol University. Mahidol University Library and Knowledge Center, 2024) Pakasit Pratoomtone; Witaya Thamavit; Somnate Boonpucknavig; Galayanee Doungchawee
    products, rubber industry, leather industry, etc. There are numerous reports showing that cancer can be induced by endogenous nitrosation from the reaction between nitrite and susceptible amine in the stomach. However, endogenous nitrosation can be blocked...Many nitrosamines are potent carcinogens in more than 40 animals including subhuman primates and possibly in man. They are present in foods, foodstuffs, beer and other beverages, tobacco and tobacco smoke, cosmetics, drugs, pesticides, rubber
