                                                  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 Waste plastic poses a dire threat to life on earth and addressing this crisis must be considered to be a priority in the field of polymer science. In this piece, several approaches to waste plastic handling are discussed, with their costs, benefits and potential for sustainability briefly outlined. Keywords: Waste plastic; Plastic pollution; Polymer; Environmental impact Introduction Virtually every eco-system on Earth is threatened by plastic pollution, directly or indirectly [1-6]. The persistent toxic nature of plastic once it has entered the environment means that plastic pollution is, arguably, a more severe long-term environmental threat than climate change. Polymer research must therefore consider environmental impact as an urgent priority for ensuring the survival of the polymer industry and, indeed, the human species. It follows that polymer design phi...
