WebThe crystal structure studied by Mencik via X-ray revealed the pseudo-hexagonal lattice (lattice parameter a = b = 0.644 nm, c = 4.15 nm, α = β = 90° and γ = 120°) in PCTFE ( Mencik, 1973 ). The main crystal planes are (101) and (102), demonstrating that PCTFE has isotactic sequences. WebPCTFE is a fluoropolymer material with outstanding strength, stiffness, and dimensional stability. It has excellent chemical and radiation resistance and good flammability characteristics. PCTFE has a broad temperature range, good resistance to cold flow, and it has the lowest coefficient of thermal expansion of any unfilled fluoropolymer.

WebThe coefficient of thermal expansion is used to determine the rate at which a material expands as a function of temperature. CTE is used for design purposes to determine if failure by thermal stress may occur. Understanding the relative expansion/contraction characteristics of materials is important for application success. WebPCTFE is a unique fluoropolymer that is capable of maintaining its physical properties at exceptionally low operating temperatures. It absorbs virtually no moisture, meaning …
