It is well known that fluoropolymer materials exhibit an excellent combination of properties, from excellent chemical resistance, wide temperature capability, electrical insulation to high purity, toughness, and non-stick properties. Alfa Chemistry Fluoropolymers provides customers with fluoropolymer tubing and rod series, including FEP, PFA, ETFE, ECTFE, MFA.
FEP has high transparency, high resistance to stress cracking, low coefficient of friction, excellent dielectric properties, and heat resistance.
PFA is the preferred choice for extended service in harsh environments involving chemical, thermal and mechanical stress.
ETFE is a fluorocarbon-based polymer that is commonly used in applications that require mechanical toughness as well as heat and chemical resistance.
The chemical resistance and extremely low permeability of ECTFE make this polymer material the first choice for use as a chemical barrier. Under prolonged exposure to ultraviolet rays and weather conditions, its performance only slightly changes, and the material is also weldable.
MFA has excellent chemical resistance, low friction coefficient, and very smooth surface. It is usually used in applications in the chemical and electrical industries that require high temperatures.
