Project Report from the year 2014 in the subject Chemistry - Macromolecular Chemistry, Polymer Chemistry, grade: AB, , language: English, abstract: In this research work TPE has been constructed by using High density polyethylene (HDPE) and Whole tire reclaimed rubber (RR). Optimized ratio of 50:50 HDPE: RR has been employed for the survey. Gamma irradiation and conventional chemical crosslinking with crosslinking coagent method were used to form a product. Results for gamma irradiation at 200KGy have been established for the best attributes.Waste management is an important issue of the 21st century. In India out of total waste generated every day; nearly 12-15% consists of polymeric waste. In this waste rubber content huge amount of itself due to growing automobile sector. It is hard to manage rubber waste as it’s not biodegradable and may be harmful to human organism. So the safe method is to reuse it as it is or by reclamation. Incorporation of this waste in the polymeric blends to form a thermoplastic elastomer (TPE) is the best way to utilize rubber waste. Thermoplastic materials like PE, PP, and PVC are cheap and widely available material to utilize for such determinations. The aim of project was to improve the overall properties of HDPE/ Reclaimed Rubber blend system and form a good example of new class of TPE. Blend of HD and reclaimed rubber shows drastic enhancement in properties which can be used in automobile and other sectors.
