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 it
s crystallinity from PFA 450HP-J
Strong point1) Suitable for applications that require improved color, lower extractable fluorides and freedom from other foreign materials.2) No additives 3) Designed for hostile chemical environments4) Reduce amount of bubbles in final parts and decreased corrosion of processing equipment5) Superior thermal material property -196 to 260 (to cover nearly all industrial chemical and solvents)℃ ℃
Application1) Semiconductor2) Fluid handling for industry or life science3) Instrumentation for precise measurement of fluid system
Reference: Neoflon PFA tubing and piping is supplied to semiconductor, TFT-LCD and chemical industry.Semiconductor (S, H, D company, Korea)TFT-LCD (S, L, B company, Korea)Equipment supplier (K, S, D company for fluid handling equipment for semiconductor and TFT-LCD)
