Pengaruh Temperatur Vulkanisasi terhadap Nilai Kelenturan (Schwartz Value/VRS) Benang Karet (Count 42 SW Ends 40) PT Industri Karet Nusantara

Abstract

Vulcanization is the one important phase in rubber thread making process. Where, the purpose vulcanization is to make the rubber thread become more elastic with using certain temperature, where the vulcanization temperature will influence one of physical properties namely Schwartz value or the resilience of rubber thread. If the temperature that used is too high (>140o C), so the value of Schwartz value is the same too, so that the rubber thread will be stiff (not elastic). And if the temperature is too low (<120o C), so the Schwartz value is the same too, so that the rubber thread will be decayed and easy to break.
