New extruded shapes made of ultra high performance polymers for large precision-machined parts

10-Apr-09
Solvay Advanced Polymers, LLC, recently announced that Advanced Polymer Technologies, LLC, (APT) is offering large stock shapes of Spire® Ultra Polymers. The new stock shapes give designers the ability to create very large machined parts while holding tight tolerances. The new stock shapes give designers the ability to create very large machined parts while holding tight tolerances. Spire® Ultra Polymers are specified by design engineers for applications that require a combination of very high performance properties. KetaSpire® PEEK (polyetherether-ketone) delivers broad chemical resistance, ease of processing, and excellent mechanical performance. AvaSpire® modified PEEK grades are tailored to meet specific performance requirements with some formulations offering more attractive economics than unmodified PEEK. PrimoSpire® SRP (self-reinforced polyphenylene) is the industry's stiffest and strongest unreinforced polymer with a unique combination of surface hardness, chemical resistance, and inherent flame-retardant properties. According to the company, the large stock shapes developed by APT are ideal for low-volume applications where fewer than 1,000 parts need to be produced annually, as well as for larger parts that are not moldable. Stock shapes also provide an excellent quality feedstock for applications that require higher flatness tolerances than could be obtained by conventional molding. Large stock shapes are most often used by the semiconductor industry (where they provide material for manufacturing equipment), aerospace, and other specialized general industrial parts. Machining parts from stock polymer shapes can produce more accurate results than molding, and unlike molding gives manufacturers the flexibility of incorporating design.
