                                                  JUNIPER PUBLISHERS-   ACADEMIC JOURNAL OF POLYMER SCIENCE Opinion The sulfur cure system in the ethylene-propylene-diene (EPDM)-based Curtain Wall Seal (CWS) has two accelerators, adding up to 2.75 parts per hundred rubber (phr) by weight, and two activators (ZnO: 5phr, stearic acid:1phr) [1]. In total, 8.75phr chemicals are used to fully cure the article with 1phr elemental sulfur. In rubber formulations, chemical curatives are indispensable and once reacted with sulfur at elevated temperature, they produce crosslinks between the rubber chains and provide shape stability, which is essential for the performance, durability and life of the final product in service. Excessive use of chemical curatives is harmful to health, safety, and the environment. According to the European Directive 67/548/E...

JUNIPER PUBLISHERS- ACADEMIC JOURNAL OF POLYMER SCIENCE Abstract Biomarkers are molecular fossils derived from living organisms and these complex compounds are composed of carbon, hydrogen and other elements. Biomarkers show little or no change in chemical structure from their parent organic molecules in living organisms [1]. Biomarkers are very useful due to their complex structures, revealing precise information about the depositional origins. It has been recognized that biomarkers in oils and rock extracts reflect depositional environment [1-3]. Therefore, biomarkers are used to achieve the objectives in such study to know the characterization of oil samples. Keywords: Fossils; Biomarkers; Oil; Isoprenoids; Marginal marine Introduction A study was conducted to analyze the oil characterizations in the oil Fields of East Java Basin (oil to oil correlation) based on biomarkers. The North East Java basin is located on the sou...
