General Description:
Polytetrafluoroethylene (PTFE) is a soft, low friction fluoropolymer with outstanding chemical and weathering resistance. PTFE is stable at temperatures up to 500°F.and it is often used in high temperature environments. The most common color of the raw material is white; other colors are available with special orders. This material, in its natural state, is heavier than water, meaning PTFE balls sink in water. The ball blanks are manufactured by rod turned to ball blanks. PTFE is purchased in virgin and reprocessed or mechanical grade bar stock.
