Phenol formaldehyde resins (PF) are synthetic polymers obtained by the effect of phenol or substituted phenol with formaldehyde.

Phenolic Balls and G-10 Glass Epoxy Balls offer excellent abrasion and impact resistance for valves, pumps, and flow control. They are a great fitting replacement for Stainless Steel in most applications. Phenolic Balls offer an exceptional combination of chemical and heat resistance with superior tensile and compressive strength compared with other plastic balls. Phenolic Balls perform as Frac Balls in Oil and Natural Gas applications.
