epoxy resin has undergone a long period of time. As early as 1891‚ the German Lindmann hydroquinone and epichlorohydrin with the reaction of condensation into the resin and make use of anhydride curing. But its value has not been revealed. Epoxy plastic has its roots far back in history‚ to be specific‚ in 1936‚ when Dr. Pierre Castan in Switzerland succeeded in synthesizing an epoxy resin that he hardened with pthalic acid anhydride. Dr. Castan’s work was licensed by Ciba‚ Ltd. of Switzerland‚

CM of Karnataka‚ Mr.Siddaramaiah promised that the dumping will stop in 5 months and the landfill will be cleared with in three year. According to experts in waste management‚ the problem can find a lasting solution only if biodegradable waste is segregated from non-biodegradable waste at the source. “In the past two years‚ many progressive changes have taken place in the way Bengaluru manages its waste. It is the first city in India where segregation of municipal waste at source has become mandatory

| Materials in Practice CP4088/CP8011 | By Clinton Chang | Synopsis This experiment is to find out the tensile strength of different plastic materials. The four plastic materials used are General Purpose Polystyrene (GPPS)‚ High Impact Polystyrene (HIPS)‚ High Density Polyethylene (HDPE) and Polypropylene (PP). By using three samples from each plastic material type‚ we are able to obtain the mean tensile strength‚ mean tensile modulus and mean yield strength of each material. With this‚ the
