Introduction of PFA tubing
Maker:
Sungwon International Co.,Ltd.
Resin:
Dupont PFA 451HP-J (Dupoint-Mitsui Fluochemical Co.,Ltd.)
Increased smoothness by minimizing spherulite size and enhanced chemical permeability resistance by increasing
its crystallinity from PFA 450HP-J
Strong point
1) Suitable for applications that require improved color, lower extractable fluorides and freedom from other foreign materials.
2) No additives
3) Designed for hostile chemical environments
4) Reduce amount of bubbles in final parts and decreased corrosion of processing equipment
5) Superior thermal material property
-196℃ to 260℃ (to cover nearly all industrial chemical and solvents)
Application
1) Semiconductor
2) Fluid handling for industry or life science
3) Instrumentation for precise measurement of fluid system
