The Tensile Behaviour of Common Engineering Polymers Abstract The mechanical properties of polymers vary significantly from polymer to polymer as a result of atomic structures and bond strength. The tensile properties of representative samples from the common polymer were tested and evaluated in this experiment. This laboratory experiment is also designed to demonstrate the procedure used for obtaining mechanical properties as modulus of elasticity‚ yield strength‚ ultimate tensile strength

consists of polyhydroxyalkanoate‚ which contain two monomers 3-hydroxybutyrate and 3-hydroxyvalerate. Bacteria growing in tanks with a carbon-based food source in which the polymer is then isolated and purified presently produce the polymer industrially. Biotechnology has been recently used to economically attempt produce the polymer using genetic engineering technique. The advantages of this process are faster growth‚ better yields‚ easier recovery‚ and production of less extra waste biomass and cheaper
