Rod PTFE Rulon® 488

sheettubeaeronautical

Overview
Rulon® 488 is a dull-turquoise, PTFE-based fluoropolymer developed for sliding and bearing applications, notably in veneer dryer bearings and gas compressor service. It delivers superior wear performance in extremely dry environments, broad chemical resistance and enhanced load capacity compared with Rulon® J and Rulon® 142.

Material & Processing
The material is a filled PTFE composite supplied as compression-molded stock and precision machined parts. Common manufacturing process: compression molding; finished components are molded or precision-machined to specification.

Typical offerings & applications

• Automatically molded bearings and components
• Sleeve, flanged and thrust bearings
• Stamped and formed seals
• Extruded shapes
• Machined parts and molded shapes

Typical applications include pumps, mixers, compressors (hydrogen and natural gas), household appliances, electrical insulators, linear slides, pipe supports and wear bands. Suitable for steam, wet, dry and vacuum environments.

Key performance characteristics

• Excellent wear resistance in extremely dry environments
• Near-universal chemical resistance (resists corrosives and trace acids)
• Higher load capacity than Rulon® J
• Better abrasion resistance than Rulon® J and Rulon® 142
• Well-suited for hydrogen and natural gas compressor applications
