Plastics and Composites
In many types of corrosive service, plastics have been found to offer many
advantages in terms of light weight and resistance to corrosion not
typically found in conventional metallic materials. For higher strength
applications, composites offer an attractive combination of both high
strength and low weight in addition to corrosion resistance. For the most
part, however, the user must be aware of the specific chemical compatibility
and temperature limits for the type of resin(s) being applied. Properties
which must be know in order to utilizes plastic successfully are, strength,
creep, modulus, thermal expansion and impact. In many service environments,
these properties can be degraded by exposure to chemicals making
characteristics such as chemical permeability a major concern.
