AMORPHOUS FLUOROPOLYMERS – A NEW-GENERATION OF PRODUCTS
Poly(tetrafluoroethylene) (PTFE) already known since 50 years, is a unique material among plastics due to its chemical inertness, heat resistance, electrical insulation properties and low coefficient of friction. its high melt viscosity needs special ways of processing. That fact led to the development of melt-processible fluoropolymers such as Perfluoroethylene-propylene (FEP) and Perfluoroalkoxy (PFA). Now we have a third generation which is an amorphous fluorpolymer made by copolymerizing tetrafluoroethylene with 2,2-bis (trifluoromethyl) – 4,5 – difluoro – 1,3 – dioxole. The bulky cyclic structure prevents the normal crystallisation as with PTFE polymers. The amorphous fluoropolymers have high clarity and dissolve in selected solvents. Having C-F, C-C and C-0 bonds the well known properties as high temperature and chemical resistance are retained. Dielectric constant is in the range 1.83 – 1.93 up to 10.00 MHz the lowest of any plastic material. Optical properties are also very special, Refractive index is very low, in the range 1.29 – 1.32. Transmission is high from UV to IR and the polymer is not photodegraded. The unique electrical and optical properties, coupled with high chemical and thermal stability, plus the ability to work from solution offers a powerful tool for those working on the frontiers of technology.
We¡¯ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, 57-50-1. The above is the message from the blog manager. Quality Control of Sucrose.
