Migration * According to the International Plastics Task Force‚ harmful chemicals -- such as acetaldehyde -- can migrate from plastic packaging to the contents of the package. Plastics associated with this concern include polystyrene‚ PVC and polyethylene. Plastic Packaging Production * Plastic packaging is produced from natural gas‚ which strains a resource that could be put to other uses. During the extended process of plastic packaging production‚ plasticizers are added to alter properties

Ligation is the process of joining two DNA fragments or other molecules by a phosphate ester linkage with the action of enzyme. Ligation of DNA is process that involve the DNA of interest is inserted into the plasmid. This 3’-hydroxyl of DNA terminus are joined together with 5’-phosphoryl of another by phosphodiester bond. The ligation of DNA fragments usually performed by using T4 DNA ligase. All the reaction components such as ligation buffer‚ DNA insert‚ pGEM®-T‚ and T4 DNA ligase is mixed by

This results in ethylene’s high reactivity. 4) Identify that ethylene serves as a monomer from which polymers are made • • • Ethylene is polymerised to polyethylene High pressures produce soft‚ low density polyethylene‚ consisting of tangled chains (with molecular masses 100‚000) 5) Identify polyethylene as an addition polymer and explain the meaning of the term Addition polymerisation: a process in which many identical small molecules combine to form one large molecule‚ with

Synopsis The main objective of tensile testing is to determine the tensile strengths and tensile modulus of different materials. Specimens that would be used are General Purpose Polystyrene (GPPS)‚ High Impact Polystyrene (HIPS)‚ High Density Polyethylene (HDPE) and Polypropylene (PP). The thickness of each specimen must be measured and recorded before being placed on the tensile testing machine. Once a specimen is placed on the tensile testing machine‚ start the machine. When the specimen is

Identification and Production of Materials ================================ Ethene‚ Polymers and Ethanol ================================ Catalytic Cracking Oil refineries need to balance their outputs of various products (petrol‚ diesel‚ fuel oil‚ etc.) to match the demands of the marketplace. Catalytic cracking is the process in which high molecular weight (high boiling point) fractions from crude oil are broken into lower molecular weight (lower boiling point) substances in order to increase

Snowboard bases are produced from ultra-high molecular weight polyethylene‚ which is also used in products such as plastic containers and bins. The polyethylene is a dense‚ plastic that resists scratches (for the most part) and has a low coefficient of friction. This means that they are very smooth and can move easily over snow. The base material can absorb wax
