METHOD FOR EXTRACTING ELASTOMER FROM TPV OR TPE

摘要

A method for extracting the elastomer for TPV(Thermo Plastic Vulcanizate) or TPE(Thermo Plastic Elastomer) is provided to enhance the efficiency and reliability in the SEM(Scanning Electron Microscopy) photographic analysis. The TPE or TPV firstly is cut with a rod shape so that pieces(1) are manufactured. The pieces are immersed into the N-heptane solvent(3) filled with a container(2), thereafter inserted into an ultrasonic device(4) and etched and processed by the ultrasonic wave during 2 hours. When applying the ultrasonic wave, the extraction of the rubber class such as elastomer is easily performed as compared with the existing method. The complete extraction of EPDM(Ethylene Propylene Diene Monomer) in the rubber class is performed.
