Description
PFA 951HP Plus is a premium fluoropolymer resin available in pellet form. PFA 951HP Plus possesses the same exceptional chemical resistance, high purity, and protection against ionic contamination as PFA HP grades with the added benefits of improved flex life and chemical stress-crack resistance. PFA 951HP Plus has unmatched HCl permeation resistance, and is also 45% less permeable to nitrogen than other PFAs (permeation by nitrogen is a general indication of the rate of permeation by other molecules). Additionally, the improved flex life and chemical resistance will reduce the cost of ownership of high purity fluid handling systems by reducing downtime caused by mechanical or chemical stresses. Parts molded with PFA 951HP Plus have an exceptionally smooth finish, which can further help prevent buildup of microbial contamination in water handling systems.
Typical Applications
Applications for PFA 951HP Plus include fluid handling components for highperformance chemical delivery systems, as well as tubing, unsupported pipe linings for the production of ultra-pure chemicals, and semiconductor components where purity in the parts-per-billion range is needed.
Processing
PFA 951HP Plus can be processed by conventional melt extrusion,and by injection, compression, transfer and blow-molding processes. High melt strength and heat stability permit the use of relatively large die openings and high temperature draw-down techniques that increase production rates. Reciprocating screw injection molding machines are preferred. Corrosionresistant metals should be used in contact with molten fluoroplastic resin. Extruder barrel should be long, relative to diameter, to provide residence time for heating the resin to approximately 380 °C (716 °F).
Food Contact Compliance
Properly processed products made from PFA 951HP Plus resin can qualify for use in contact with food.
Storage and Handling
Special product isolation and packaging procedures are used to eliminate external contamination of PFA 951HP Plus resin. Processors also must avoid contamination for successful production of high purity products. The properties of PFA 951HP Plus resin are not affected by storage time. Ambient storage conditions should be designed to avoid airborne contamination and water condensation on the resin when it is removed from containers.
Packaging
PFA 951HP Plus is supplied as pellets and is available in 25-kg multilayer bags with an integral polyethylene liner.
