True or False: A primary package is defined as the packaging that makes a product a sell-able unit. 1 Basketball court. Why does PVC (polyvinyl chloride) have different properties from polyethene? HMW phthalates are safely used in many everyday including cables and flooring. PVC has excellent electrical insulation properties, making it ideal for cabling applications.    6.1  Environmental Impacts Other sporting applications: performance sports surfaces, sports equipment, clothing, protective barriers, matting, wiring and piping infrastructure. Rubber. PVC and XLPE materials which have been cross-linked to make them thermoset materials also have enhanced resistance to temperature, improved dielectric strengths and resistances to certain chemicals. The liquid crystallinity in polymer may occur by _____ & _____ 4. 4. The most commonly used plasticisers are phthalates which can be divided into two distinct groups with very different applications and classifications; Thermosetting plastics cannot be softened on heating, therefore they cannot be moulded and reshaped. Question 21. Such a material is also known as a thermoset or thermosetting polymer. Examples of thermoplastics that are common in engineering include: ABS (acrylonitrile butadiene styrene)- stiff and light, used in vehicle bodywork . Which is a thermosetting plastic? Answer 2 Grind the PVC coating to 5 mil before treading. Require heat to make them formable and when cooled they maintain the shape they were formed in to. The material now accounts for about 20% of all plastic manufactured world-wide, second only to polyethlene. Can be deformed a large amount when a force is applied and can return to their original shape when released. Answer: (False) Correct statement: It is good to wear clothes made of fibres while cooking. Chlorine is used in the manufacture of life-saving medication, indeed 85% of all pharmaceuticals. The figure shows the different molecular structures of a thermoplastic and a thermoset.    5.3 Electronics Examples include polyethylene (PE),polystyrene, polypropylene (PP) and polyvinyl chloride (PVC). The BPF has a dedicated Additives Group, as well as a Masterbatch and Technical compounds Group. The cross-linking process eliminates the risk of the product remelting when heat is applied, making thermoset plastics ideal for high-heat applications. Answer: 4R’s stands for Redue, Reuse, Recycle and Recover. The first patent for a polymerisation process to manufacture PVC was granted to German inventor Friedrich Klatte in 1913 and PVC has been in commercial production since 1933. The plastic used for making optical lenses is _____ 6. Question 13. Picture: Kind permission of ECVM.    6.4  Total Cost of Ownership Study They are easily molded and extruded into films, fibers and packaging. 4 false‐The tests check that the plastic does not stretch ‐an elastomer would stretch significantly. Optional additives, include a range of substances from processing aids, impact modifiers, thermal modifiers, UV stabilisers, flame retardants, mineral fillers, pigments, to biocides, and blowing agents for specific applications. 5. The blending of PVC polymer with other materials to produce different formulations providing a wide range of physical properties. PVC has been used for hundreds of life-saving and healthcare products for almost 50 years being used in surgery, pharmaceuticals, drug delivery and medical packaging due to its unrivalled performance characteristics and cost-efficiency.
