Polypropylene (PP) is a linear hydrocarbon polymer, expressed as CnH2n. PP, like polyethylene (see HDPE, L/LLDPE) and polybutene (PB), is a polyolefin or saturated polymer. Polypropylene is one of those most versatile polymers available with applications, both as a plastic and as a fibre, in virtually all of the plastics end-use markets.
Mar 01, 2022 · That is about ten times more than what standard well water filters offer. If a 100,000-gallon unit can last a year, there is no question this filter membrane will reach a decade of service before requiring a replacement. The filter removes up to 99.6% of chlorine, chloramine, VOCs, organic compounds, and other substances present in well water.
Jul 16, 2019 · Microbial resistance to classical antibiotics and its rapid progression have raised serious concern in the treatment of infectious diseases. Recently, many studies have been directed towards finding promising solutions to overcome these problems. Phytochemicals have exerted potential antibacterial activities against sensitive and resistant pathogens via different mechanisms of action. In this
