Petrochemicals industry is also a important contributor to the exchequer of the country where polymer Segment alone contributes around 8‚000 crores of Indian rupees in form of taxes and import-export duties. Slow growth in this industry will hence result into smaller government income and larger fiscal deficit which will have an adverse impact on

(CDIO) 1. Synopsis The objective of this CDIO experiment was to determine the mechanical property of polymeric materials which was the tensile properties .The testing standard to adopt for the tensile testing was ASTM D638. Four different types of polymers were placed into the tensile testing machine. The different specimens would then be stretched till it breaks. The tensile testing machine would give the information on the force that was required to stretch the different specimens until it breaks

in the body. Macromolecules (also known as supermolecules) are commonly grouped into four major categories: proteins‚ nucleic acids‚ lipids and carbohydrates. These are mainly composed of polymers‚ long molecules made up of a large number of small‚ similar molecules‚ or monomers. Proteins are polymers of amino acids. Long amino acid chains are folded into complex shapes‚ the shape of each determining the function of the protein. They are complex organic compounds‚ essential to the functioning

statement: In this case‚ unless the director of the Polymers Department‚ Paul Burke‚ in the Corporate Technology Development division of Crutchfield Chemical Engineering is able to resolve large difference among teams in the Lumen and Absorb Teams‚ the Crutchfield Chemical Engineering may continue to affect its creativity‚ employee motivation and working environment. Analysis: As one of three departments in Crutchfield Chemical Engineering‚ Burke’s Polymers Department had five project teams in that time

Fast dissolving oral film‚a new kind of drug delivery system‚ is a stamp-style drug loaded polymer film with rapid disintegration and dissolution in the saliva ‚self‑administration without water or chewing. It offers higher compliance against swallowing difficulty of conventional solid dosage form‚especially suitable for patients who have fear of choking such as pediatric and geriatric patients. However‚fast dissolving oral film is not suitable for poorly soluble drug because of the grittiness taste

Pineapple peel fiber which have high content of cellulose‚ low density‚ abundance and low cost‚ have the potential for polymer reinforcement. This study aims to determine the effectiveness of corn starch film reinforced with Pineapple Peel fiber. Testing procedure was formulated using extended MECMESIN Advance Force Gauge AFG 25N in Licton Industrial Corporation‚ which specializes

Fi‚rthermore‚ during acute diarrhea in infancy‚ soluble polymers of glucose derived from corn are well tolerated. The use of polymers of glucose have the advantage of providing the infant with potential mucosal injury with a carbohydrate source that can be readily absorbed and has a high caloric density with low osmolality (2). It seems‚ therefore

MSE 313 Department of Materials Science and Engineering Spring 2005 Laboratory 7 Creep of Polymers Objective The aim of this laboratory is to demonstrate the phenomenon of creep in materials and its effect on the long term mechanical performance of materials. YOU MUST READ ASTM STANDARD D2990-01 BEFORE THE LAB Introduction Most of the materials experience time dependent permanent deformation as a function of time at a constant stress and this phenomenon is called creep

Research Question: Should the use of plastic bags be encouraged for grocery and shopping purposes? 1.0 Introduction and chemistry background Plastic or its scientific name polyethylene is a type of polymer. Polymers are defined as a large molecules consisting of specific small repeating monomers that combine or react together. In this case‚ plastic or polyethylene is made up of small monomers called ethylene (ethene). Ethylene molecules react and combine together through addition reaction/polymerization
