Global Polypropylene Market 2014-2018 Polypropylene is the single most widely used polymer resin in the world. It is one of the most versatile plastics made from polyolefin. Polypropylene accounted for more than 20 percent of the total polymer demand‚ worldwide. It is produced by the polymerization of propylene. There are three main grades of polypropylene produced: homopolymer‚ co-polymer‚ and impact co-polymer. Polypropylene possesses intrinsic properties of high stiffness‚ good tensile strength

starch and test its properties. Potato starch is a polymer made of long chains of glucose units joined together. It actually contains two polymers: q q Amylose‚ which is a straight chain of glucose units Amylopectin‚ which is a branched polymer‚ also made of glucose units. The amylopectin prevents the starch from becoming plastic-like. You will use hydrochloric acid to break down the amylopectin and change the stucture and properties of the polymer. You will make two different batches of the potato

Immobilization of Enzymes And Their Applications By‚ Shudhangshu Shekhar Kundu Introduction: What an enzyme? Enzymes are protein molecules‚ which serve to accelerate the chemical reactions of living cells (often by several orders of magnitude). Without enzymes‚ most biochemical reactions would be too slow to even carry out life processes

Plastics are one of the classification of polymers .If a polymer is shaped into hard and tough utility articles by the application of heat and pressure ‚it is used as “plastic”. Synthetic polymers are often referred to as "plastics"‚ such as the well-known polyethylene and nylon. However‚ most of them can be classified in at least three main categories: thermoplastics‚ thermosets and elastomers. Man-made polymers are used in a bewildering array of applications: food packaging

consideration for their ultimate disposability or recyclability. This has resulted in mounting worldwide concerns over the environmental consequences of such materials when they enter the waste stream after their intended uses‚ Of particular concern are polymers used in single use‚ disposable plastic applications. Plastics are strong‚ light-weight‚ inexpensive‚ easily process able and energy efficient. They have excellent barrier properties. They are disposable‚ and very durable. However‚ it is these

Research on Biopolymers Biopolymers are polymers that those that are made from living things and can be broken down by micro-organisms when released into the environment. Polyhydroxybutyrate (PHB) is a polyhydroxyalkanoate produced by a microorganism called Alcaligenes Eutrophs. The bacterial culture is given abundant nutrient for rapid replication. Nutrient supply is then drastically reduced and the bacteria converts the available food into energy storage. This is produced in the form of PHB. PHB
