Item Metadata only A study of impact modification of polyamide 6 using natural rubber(Mahidol University. Mahidol University Library and Knowledge Center, 2023) Panthip Monthachitra; Axtell, Frederick Henry; Krisda Suchiva; Pranee Phinyocheephydrazine. Ultranox 626 was selected out of 11 types of commercial antioxidants as a suitable one for the PA6/NR blend system. The rubber particle dispersion in the PA6/TTR5L NR blends were compared for three mixing processes: 2-roll mill, Haake... dispersion, and it was obtained (18 kJ/m2 for the blend containing the rubber molecular weight of 290,000 that has the average rubber particle size of 0.24 micron. The rheological studies of the blends were conducted, and it was found that the rubberItem Metadata only The interactions between compatibiliser activity under melt processing conditions and the morphology and mechanical properties of polyamide 6/polypropylene blends(Mahidol University. Mahidol University Library and Knowledge Center, 2000) Adisakdi Chatathanom; Venables, Richard A.; Krisda Suchiva; Arunee Tabtiangwere twin screw extruder screw configuration, screw speed, and compatibiliser concentration. The level of dispersion of the minor component in the blend and the dispersion stability were quantified through analysis of extruded and injection mouldedItem Metadata only A study of the toughness of rigid PVC filled with recycled vulcanised elastomer dust(Mahidol University. Mahidol University Library and Knowledge Center, 2023) Wararat Sophanowong; Axtell, Frederick Henry; Pranee Phinyocheep; Orapin Phaovibul2 for unmodified PVC. The impact behavior was dependent on dust type and level of dust loading Sieving the laminate scrap dust prior to mixing did not improve the dispersion level or impact strength. The 20% and 25% loadings of midsole scrap dustItem Metadata only A study to develop thermoplastic elastomers from natural rubber and plastic blends(Mahidol University. Mahidol University Library and Knowledge Center, 2023) Wannee Surangsopon; Krisda Suchiva; Axtell, Frederick Henry; Orapin Phaovibulof DCP:HVA-2 crosslinked, the SEM micrographs showed that NR and PP were co-continuous phases. For NR/PP 70/30 blends. SEM micrographs showed that NR was the continuous phase while PP was the dispersed phase. The NR/PP blends prepared also exhibitedItem Metadata only A study of processing aid action in rubber processing(Mahidol University. Mahidol University Library and Knowledge Center, 2023) Chaiwat Ruksakulpiwat; Krisda Suchiva; Pranee Phinyocheep; Prasert Khunkamchooof the present study suggested that good processing aids should process the ability to reduce the elasticity of the rubber, for efficient incorporation of carbon black as well as the viscosity, for good dispersion and distribution of the filler.Item Metadata only Morphology and mechanical properties of kevlar pulp/styrene (ethylene butylene) styrene thermoplastic elastomer composite(Mahidol University. Mahidol University Library and Knowledge Center, 1997) Teeravut Nakinpong; Sauvarop Bualek; Wiriya Meesiri; Taweechai Amornsakchaito be only slightly decreased. Mixing condition for the preparation of Kevlar pulp-SEBS composites in an internal mixer which give the highest value of tensile properties and good fibre dispersion was found to be 165 degree C with rotor speed of 90 rpm
