| 备注说明 | UNIPET PET from Nytef Plastics is a semicrystalline polyester terephthalate (PET) polymer that exhibits excellent strength, rigidity, and machinability. Additionally, this material offers dimensional stability and wear resistance that meets or exceeds that of nylon or acetal. Due to it's superior chemical resistance and food contact approvals, UNIPET PET stock shapes are the preferred material for components in food processing applications such as pistons, valves, feed screws, andfood product forming and extrusion dies. Additionally, the low moisture absorption and low rate of thermal expansion offered by UNIPET makes it ideal for demanding applications that require close tolerance, precisely machined component parts. UNIPET PET machines easily and is offered by Nytef Plastics in a complete range of extruded rod and heavy gauge plate sizes.UNIPET PET ATTRIBUTES TYPICAL INDUSTRIES APPLICATIONS |
