摘要： A coating created entirely from plant-derived ingredients is disclosed. Illustrative embodiments of the coating may be particularly well suited for use on leather-like materials created from epoxidized natural rubber-based formulations. Illustrative embodiments of the coating created may be comprised of substantially the reaction product between epoxidized vegetable oil and a polyfunctional naturally occurring acid (such as citric acid). Illustrative embodiments this reaction product may be used to produce porosity-free castable resins and vulcanize rubber formulations based on epoxidized natural rubber. Materials made from disclosed materials may be advantageously used as leather substitutes.

摘要： A modified polymer includes a diene-based polymeric chain and at least one end terminated with a blocked isocyanate group. The blocked isocyanate group may be the reaction product of an isocyanate and a blocking agent, and the blocking agent is selected, such that the modified polymer deblocks at temperatures of at least 100 C. An aqueous emulsion of the modified polymer may be provided that may be surfactant-free. The emulsion may be combined with one or more latexes to provide a treatment solution for a fabric or fiber that does not require the use of resorcinol and formaldehyde. Once treated and dried, the fabric or fiber may be used to impart tensile strength to rubber products, such as tires, air springs, flexible couplings, power transmission belts, conveyor belts, and fluid routing hoses.

摘要： A solution based polymer nanofiller composite processing method to improve mechanical, electrical, thermal and/or chemical properties. The solution based synthesis method may include the steps of surface functionalizing carbon nanomaterials and dissolving a polymer in a solvent. The functionalized carbon nanomaterials and dissolved polymer may be mixed until the mixture is homogenous. The mixture may be cured to form the polymer carbon nano-composite material, which provides significant improvements in modulus, hardness, strength, fracture toughness, wear, fatigue, creep, and damping performance.

摘要： A process for recovering wastes of a polymeric composition including at least one peroxide-curable polymer and at least one peroxidic crosslinking agent, which includes compounding the wastes with at least one antioxidant agent suitable for sulfur-vulcanized elastomeric compositions, at a temperature lower than the decomposition temperature of the at least one peroxide crosslinking agent. The compounding of the polymeric wastes with the antioxidant agent is carried out at a temperature lower than the decomposition temperature of the peroxide crosslinking agent, so as to avoid any premature activation of the crosslinking agent. The process is particularly suitable for compositions based on elastomeric polyolefins, more preferably for elastomeric ethylene copolymers such as ethylene-propylene copolymers (EPR) and ethylene-propylene-diene terpolymers (EPDM), which can be processed at relatively low temperatures, much lower than the decomposition temperatures of the most common peroxide crosslinking agents.

摘要： Epoxidised natural rubber [ENR] based vulcanised-blends with two different types of electrical conductive filler (i.e. conductive grade-carbon black and intrinsically electrical conductive polymer) may be produced respectively by using either internal mechanical mixing method or open milling method or the combination of the two methods. All these ENR based vulcanised-blends show high consistent reversible electrical behaviour under the tensile straining process. They also exhibit useful mechanical properties with tensile strengths up to 28.0 MPa, elongations at break up to 800.0% and Dunlop rebound resiliencies up to 55.0%. The lower the rebound resilience, the better the damping property and shock absorption ability for the ENR based vulcanised-blends. As a result, these ENR based vulcanised-blends are ideal to be used for manufacturing flexible sensors that may correspond to the tensile straining process.
