The costs of the materials and processing of the controlled release preparation, are substantially higher than those of standard formulations. Biodegradable synthetic polymers offer a number of ad-vantages over other materials for developing scaffolds in tissue engineering. Purely synthetic fibres, on the other hand, are made from chemicals. Lighter in weight 2. polymer, the utilisation of the polymer in certain applications and its occurrence in specific waste flows. However, polymers that are synthesized chemically by humans from biological sources such as vegetable oils, fats, resins, sugars, proteins, and amino acids can also be described as biopolymers (Hernández et al., 2014).As compared with synthetic polymers, … Polymer banknotes pros and cons Business The Guardian. Polymers are more resistant to chemicals than their metal counterparts. of Chemistry. Fabrics made of synthetic fibres are generally more durable, … They can also be fully synthetic fibers such as nylon or acrylic fibers. DISADVANTAGES OF HER BAL POLYMERS . Polymers also play a significant role in being a part of the materials that are used in and on the soil to improve aeration which is the phenomenon of creating air spaces between the soil for more permeability of water and minerals. In melt spinning polymer (fibre-forming substance) is melted and pumped through a spinneret (die) with numerous holes (one to thousands). His articles have appeared in "Plenty," "San Diego Reader," "Santa Barbara Independent" and "East Bay Monthly." As new polymers went into the development process, the plastics advantages and disadvantages required constant review to avoid detrimental environmental impacts.
