Benefits and Applications of Electroactive Polymer Actuators. 14/03/2009в в· disadvantages: in the production stage, polymers are susceptible to contamination. the least bit of dirt or cross-contamination w/other polymers, and at best the end product is corrupt, at worst the polymers are rendered useless. any variances in heat and timing in the molding process and, again, the final product will be corrupt or useless., advantages. cheap to make; many uses because of their different properties. provide jobs in firms which make the polymer and the product. some polymers can be recycled, melted down and made into something else which saves valuable natural resources.).

Due to the industrial revolution, many chemical compounds are synthesized, which are of great use for human being. But these are unknowns for the environment. Plastic is one of the few newly synthesized chemical compounds that utilize synthetic polymers like polyethylene, polyvinyl chloride There are advantages and disadvantages to many of these soil stabilizers. Many of the “green” products have essentially the same formula as soap powders, merely lubricating and realigning the soil with no effective binding property.

Disadvantages of polymers are: - non bio-degradable - easily breakable - flame retardancy is low - when polymers incorporated with additives are burnt they emit a lot of poisonous gases into the atmosphere Abstract. Merits of composite precursors, i.e. thermoplastic and thermoset matrices for continuous fibre composites, can only be established providing that their chemical, physical and engineering aspects are considered on three levels required for converting simple organic molecules into a composite structure that meets design requirements

Dental composite materials which are used as tooth fillings have numerous advantages and disadvantages in comparison to previously used alternative materials. Effects of polymerization shrinkage (light curing) of composite polymer materials which occur after illuminating with a LED lamp can cause problems in dental practice. Considered in this paper were the mechanical consequences … What are the Advantages and Disadvantages of Synthetic Fibres Advantages of Synthetic Fibres Synthetic fibres have the following advantages. Most synthetic fibres have good elasticity. Most fabrics made of synthetic fibres do not wrinkle easily. Fabrics made of synthetic fibres are generally more durable, less expensive, and more readily

ADVANTAGES AND DISADVANTAGES OF THERMOSET AND THERMOPLASTIC MATRICES FOR CONTINUOUS FIBRE COMPOSITES A. CERVENKA Manchester Materials Science Centre, polymer chain mobility, polymer chain conformation, degree of polymer chain ordering or crystallinity can all vary significantly and continuously from the interface with the reinforcement into the bulk of the matrix. This large amount of reinforcement surface area means that a relatively small amount of nanoscale reinforcement can have an observable effect on the macroscale properties of the
