Publication Metadata only Phase structure and property relationships in ternary polypropylene/elastomer/filler composites: Effect of elastomer polarity(2000-01-01) K. Premphet; P. Horanont; Mahidol UniversityTernary composites of polypropylene (PP), elastomer, and calcium carbonate (CaCO3) filler were prepared to study their structure/property relationships. Two kinds of phase structure were formed, depending on the elastomer present in the composites.... Separation of elastomer and filler particles was found when a nonpolar ethylene-octene copolymer was used. Encapsulation of filler by the elastomer was achieved by using a polar ethylene-vinyl acetate elastomer. The mechanical properties of ternary compositesPublication Metadata only Phase structure of ternary polypropylene/elastomer/filler composites: Effect of elastomer polarity(2000-09-14) K. Premphet; P. Horanont; Mahidol UniversityPhase structure of ternary polypropylene/elastomer/calcium carbonate composites has been investigated using scanning electron microscopy, dynamic mechanical analysis and differential scanning calorimetry. Two kinds of phase structure were observed... either a separate dispersion of the phases or encapsulation of the filler by elastomer. The composite phase structure was determined mainly by the chemical character of the components and, to a lesser degree, by the mixing sequences of each componentItem Metadata only Mechanical properties and morphology of conex short fibre/thermoplastic elastomer composites(Mahidol University. Mahidol University Library and Knowledge Center, 1998) Anongnuch Chantaratcharoen; Sauvarop Limcharoen; Taweechai Amornsakchai; Chakrit SirisinhaItem Metadata only Effect of fibre surface treatment on the interfacial adhesion between aramid fibre and thermoplastic elastomer(Mahidol University. Mahidol University Library and Knowledge Center, 2001) Yodpant Bunsanong; Sauvarop Limcharoen; Taweechai Amornsakchai; Sombat ThanawanItem Metadata only A study of phase structure formation and mechanical properties of ternary composites of polypropylene, elastomer and filler(Mahidol University. Mahidol University Library and Knowledge Center, 1999) Pornsuda Horanont; Kalyanee Premphet; Krisda Suchiva; Pranee PhinyocheepItem 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 PhaovibulThis study utilized vulcanized elastomer dust as an impact modifier in polyvinyl chloride (PVC) compound. Three types of waste dust are generated during sports shoe soles manufacture: midsole waste (scrap dust of vulcanized EVA foam), outsole waste...) was used to assess the fusion level of PVC. The morphology of PVC modified with vulcanized elastomer dust was studied utilizing optical microscopy. The particle size distribution of dusts before and after processing were measured from photomicrographsPublication Metadata only Self-reinforcing elastomer composites based on polyolefinic thermoplastic elastomer and thermotropic liquid crystalline polymer(2008-02-15) Sunan Saikrasun; Taweechai Amornsakchai; Mahasarakham University; Mahidol UniversityIn situ reinforcing elastomer composites based on Santoprene thermoplastic elastomer, a polymerized polyolefin compound of ethylene-propylene-diene monomer/polypropylene, and a thermotropic liquid crystalline polymer (TLCP), Rodrun LC3000, were... containing 5-10 wt % LC3000 appeared as droplets. At 20 wt % LC3000 or more, the domain size of TLCP became larger because of the coalescence of liquid TLCP threads that occurred during extrusion. The addition of LC3000 into the elastomer matrix enhancedPublication Metadata only Phase behavior and properties of in situ-reinforcing elastomer composites based on thermoplastic elastomers and thermotropic liquid crystalline copolyester(2006-08-05) Sunan Saikrasun; Taweechai Amornsakchai; Mahasarakham University; Mahidol UniversityIn situ reinforcing composites based on two elastomer matrices very different in melt viscosity, styrene(ethylene butylene)-styrene triblock copolymer (Kraton G1650) and styrene-(ethylene propylene) diblock copolymer (Kraton G1701), and a... because of the coalescence of liquid TLCP threads that occurred during extrusion. The addition of LC3000 into both elastomer matrices enhanced the tensile modulus considerably whereas the extensibility remarkably decreased. The results obtained fromPublication Metadata only Structure-mechanical property correlations of model siloxane elastomers with controlled network topology(2009-01-16) Kenji Urayama; Takanobu Kawamura; Shinzo Kohjiya; Kyoto University; Kanazawa University; Mahidol UniversityWe review our recent studies towards the molecular understanding of mechanical properties-structure relationships of elastomers using model polydimethylsiloxane (PDMS) networks with controlled topology. The model elastomers with controlled lengths... elasticity are assessed in an unambiguous manner on the basis of the nonlinear stress-strain behavior of the model elastomers under general biaxial strains.
