Definition - What does Terpolymer mean?
A terpolymer is a chemical compound resulting from a polymer that has a molecular structure built mostly or completely from a large number of similar units bonded together (such as a complex resin). A terpolymer is a result of the copolymerization of three different monomers, and is sometimes used to prevent corrosion.
Corrosionpedia explains Terpolymer
Terpolymers are used to produce biodegradable porous shape-memory scaffolds, and for wire and cable coverings. Terpolymers may be cross-linked by an electron beam to improve their strength while increasing their softening temperature. They are also used as primary insulation for various applications where flexibility is required.
