The document discusses the properties and applications of several fluoropolymer materials: - PFA (perfluoroalkoxy) is chemically inert and resistant to strong acids/bases. It is used in non-shrink tubing, heat exchangers, medical tubing, cable coating, and lining chemical equipment. - PVDF (polyvinylidene fluoride) has high purity and strength, resisting solvents, acids, bases and heat. It is used where its lower melting point is advantageous for melt processing. - PCTFE (polychlorotrifluoroethylene) is rigid with low gas permeability and compressive strength. It maintains properties at high temperatures and in chemicals. -

PVDF Properties PVDF (KYNAR®) is generally used in applications requiring the high purity, strength, and resistance to solvents, acids, bases and heat. Compared to other fluoropolymers, like PTFE, PFA, FEP, it has an easier melt process because of its relatively low melting point of around 177°C.

PCTFE Properties PCTFE or CTFE (originally known as Kel-F*) has many of the properties similar to other fluoropolymers such as PTFE, FEP or PFA, but is mechanically superior in rigidity (does not deform easily), and has very low gas permeability . Its dimensional stability makes it attractive for use as a component of a structural part where the high temperature and chemical resistance of fluoropolymers is required. PCTFE shows high compressive strength and low deformation under load. However, its relative cost is one of the major considerations in its selection, since it is quite expensive.

ETFE Properties ETFE is distinguished from perfluopolymers (totally fluorinated polymers) as a partially fluorinated copolymer of ethylene and TFE. This chemical modification provides significantly higher strength relative to PTFE, FEP or PFA. It is less flexible than PTFE, but has superior impact strength, abrasion and cut through resistance. Addition of a third component to the chemical structure creates a modified ETFE that has lower weight per unit volume, is stiffer and tougher than PTFE, PFA or FEP. These properties allow it to withstand greater physical abuse during its lifetime. For example, glass reinforced ETFE has outstanding wear characteristics and may be used for bearing applications. ETFE is also suitable for pump impellers or moving parts of equipment that are operating in chemically aggressive environments (check to ensure chemical compatibility).
