Polypropylene

number 1, degradability, is not the most important criteria, and number 7, cost, is not necessarily the least. Most of the potty used in healthcare nowadays are made of ubiquitous polymers such as Polyethylene and Polypropylene, which are generally non-biodegradable under normal environmental conditions. Thus, degradability is significantly low. For an overnight-or-one-day use product like healthcare potty, such low degradability is fatal to the environment, since they…

A diluted sulfuric acid electrolyte: with a specific gravity of 1.280 (when fully charged) A plastic container: the container is divided into six compartments, and each plate is connected in series to make up 12V. A cover: Impact resistant polypropylene case Valves: Self-sealing safety valves with flame proofing The rugged cell construction provides maximum vibration resistance and extends the product…

What is Styrofoam? Styrofoam is a brand of closed-cell extruded polystyrene foam currently created for thermal insulation and craft applications. Dow Chemical Company retained and produced the Styrofoam. Through petroleum product known as styrene, Styrofoam was created. The styrene is amended into a clear molten mass of polystyrene through a complex chemical process known as polymerization. It would become a hard plastic if it were left to cool. Disposable eating utensils are created from this…

Instead of the turf containing nylon fibers, it was made with polypropylene, which was more comfortable. This first generation of turf was what we now call carpet. In the late 1970’s, the second generation of turf was developed. The plastic fibers were not only spaced wider apart to mimic natural grass, but they contained…

1 Cardiopulmonary bypass (CPB) 1.1 Introduction Cardiovascular diseases are the leading cause of death globally. Different types of cardiac operations are performed every day in hospitals varying in complexity to treat several lesions such as coronary artery bypass graft, heart valve replacement and total heart replacement. Cardiopulmonary bypass (CPB) is a crucial technique employed in the majority of these operations (Punjabi and Taylor 2013). It takes over the function of the heart and…

The available technology points toward the use of lead/acid batteries to supply the power for ZEVs. The negative consequences associated with lead/acid batteries are numerous. For example, lead/acid batteries contain a large amount of lead. When the life of the battery is lost, the disposal of the lead within the battery must be dealt with appropriately. An analysis by researchers at Carnegie-Mellon found that the mass production of electric cars using lead/acid battery packs would exponentially…

Raw material Boneless, skinless chicken breasts were purchased freshly from the butcher shops. Samples were prepared in average weight of 80±7 g fillets. All fillets including control and treated were packed in polypropylene trays and kept under refrigerated condition (4 °C) for 16 days. Preparation of LPOS LPOS was made at weight ratios of 1.00; 0.35; 108.70; 1.09 and 2.17 for LPO, glucose oxidase, α-D glucose, KSCN, and KI, respectively (15.5 mg of LPO was added) (Cissé et al.…

Literature review Polymerisation of Cyclo pentene, Cyclo hexanes, Substituted Cyclo pentene and Cyclo hexanes using different catalyst Introduction:- Polymer is a word which is derived from Greek words “poly” which means many and “mer” which means parts. Polymers are substances which have large number of repeating structural units repeated in the same type of linkage. The chemistry that deals about polymers is called polymer chemistry and the reaction is called as polymerization. Polymer…

several times and kept for air drying. The product is stored in air tight container at 25-35celsius.[38] Experimental animals Swiss mice of either sex, 8-10 weeks old, weighing about 25-30 g were used in Experiments. Animals were housed in polypropylene cages maintained under Standard condition (12 hours light / dark cycle; 25 ± 3 0C, 45-65% humidity) and had Free access to standard rat feed (Hindustan Liver Ltd., India) and water ad libitum All the animals were acclimatized to laboratory…

Executive Summary: Waste has become a global problem. It has become very necessary to address this problem, so that energy problems can be solved. 50 million tonnes of domestic waste is produced every year, and this is a health hazard. Domestic waste is nothing but paper, kitchen waste, and plastic. Plastic is the common term for a wide range of synthetic or semi-synthetic materials used for a huge and growing range of applications. We can find plastic in most of the items that we use today,…
