Establishing rubber dandelions and guayule in the United States via premium markets to secure essential supplies

Cornish. J. Cardina K., Fresnedo J., Michel_Jr. F.C., Cornish. J. Cardina K., Fresnedo J., Michel_Jr. F.C., The Ohio State University, US

Natural rubber and latex are imported, critical, agricultural raw materials essential to all sectors of the US economy and cannot be replaced by unsustainable petroleum-derived synthetic rubbers due to their performance deficiencies. National security is [...]

Sustainable Technology Solutions – Natural rubber to replace plasticized PVC in exterior durable application – A case study by NZ Product Accelerator model of engagement of supply chain partners

De Silva K.K.G., Taylor M., Nilmini R., Kariyawasm S., Vithanachchi J., NZ Product Accelerator - University of Auckland, NZ

Rigid PVC is flexibilized by the addition of plasticizers such as phthalates to obtain the properties of elastomers. These plasticizers in the polymer matrix are not covalently bound to the main polymer chain, which makes [...]

Degradability of polymeric composites (ENR/PLA) from renewable resources

Masek A., Zaborski M., Lodz University of Technology, PL

In our research, we reported on biodegradable composites exhibiting specificity properties by melt blending of polylactide (PLA), one of the commercially available biodegradable material, and epoxidized natural rubber (ENR). Blending of ENR with different types [...]

The study of using glycidyl methacrylate grafted natural rubber as an impact modifier of polylactic acid

Juntuek P., Ruksakulpiwat C., Ruksakulpiwat Y., humsamrong P., Ruksakulpiwat C., Ruksakulpiwat Y., Suranaree University of Technology, TH

Glycidyl methacrylate (GMA) was grafted onto natural rubber (NR) using emulsion polymerization method and using cumene hydroperoxide (CHP) and tetraethylenepentamine (TEPA) as an initiator. Glycidyl methacrylate grafted natural rubber (NR-g-GMA) were melt blended with polylactic [...]

Real time Crystallization of Nanoparticles Filled Natural Rubber Under Stretching

Carretero-González J., Verdejo R., Toki S., Hsiao B.S., Giannelis E.P., Lopez-Manchado M.A., Polymer Science and Technology Institute, ES

Polymer nanocomposites (PNCs) represent an alternative new class of materials compared to conventional filled polymers or polymer blends, as they can possess enhanced properties through nanoscale reinforcement.[1] A great deal of efforts have been devoted [...]

Strain-induced Crystallization and Mechanical Properties of Carbon Nanotubes Reinforced Natural Rubber

Jeon H.-J., Kang M.K., Song H.H., Kwag G., Choi H., Hannam University, South Korea, KR

Natural rubber is an elastomeric material and its ability to crystallize at large deformations results in an extraordinary toughness. However, natural rubber needs the reinforcing materials to improve the mechanical strength, thermal stability and abrasion [...]
