3.半透明粒料,注塑、挤出成型。成型温度350-400摄氏度,475摄氏度以上容易引起变色或发生气泡。并注意脱模会较困难。
4、因熔融的材料对金属有腐蚀作用,长期生产,模具需要电镀铬处理。
全氟烷氧基树脂
PFA树脂相对来说是比较新的可熔融加工的氟塑料。
PFA的熔点大约为580F,密度为2.13— 2.16g/cc(克/立方厘米)。PFA与PTFE和FEP相似,但在302T以上时,机械性能略优于FEP,且可在高达500F下的温度下使用,它的耐化学品性与PTFE相当。PFA的产品形式有用于模塑和挤塑的粒状产品,用于旋转模塑和涂料的粉状产品;

PFA的产品形式有用于模塑和挤塑的粒状产品,用于旋转模塑和涂料的粉状产品;其半成品有膜、板、棒和管材。美国市场经销的PFA树脂有DUPOut公司的Teflon牌、Daikin公司的Neoflon牌、Ansimont公司的Hthen牌、HOechstCelanese公司的Hostafl牌。PFA的用途与FEP类似。
3. Translucent granular material, injection molding, extrusionmolding. The molding temperature is 350-400 ℃, and above 475 ℃, itis easy to cause discoloration or bubbles. And notice thatdemoulding will be more difficult.
4. Because the molten material has corrosive effect on themetal, the mold needs chrome plating for long-term production.
Perfluoroalkoxy resin
PFA resin is relatively new fluoroplastics that can be meltedand processed.
The melting point of PFA is about 580F, and the density is2.13-2.16g/cc (g/cm3). PFA is similar to PTFE and FEP, but itsmechanical properties are slightly better than FEP when it is above302T, and it can be used at temperatures up to 500F, and itschemical resistance is equivalent to that of PTFE. PFA productsinclude granular products for molding and extrusion, and powderproducts for rotary molding and coating;

PFA resins distributed inthe U.S. market include DuPOut's Teflon brand, Daikin's Neolonbrand, Ansimont's Hthen brand, and HOechst Cellanese's Hostaflbrand. The use of PFA is similar to that of FEP.
