Polymer Balls

G-10 Phenolic

G-10 Phenolic is a continuous woven glass fabric laminated with an epoxy resin. Balls made from this material are extremely high in mechanical strength. In addition, G-10 Phenolic balls have low water absorption and dissipation factors. They also have exceptional electrical characteristics – which are exhibited over a wide range of temperatures and humidities.

G-11 / FR-4 Phenolic

G-11 / FR-4 Phenolic is similar in composition and properties to G-10 but better suited for continuous use at elevated temperatures. G-11 retains at least 50% of its structural strength at continuous operating temperatures in excess of 300°F.

Nylon (PA6)

NYLON GF (Polyamide 6, standard and heavy-weight) balls offer excellent pressure and chemical resistance at an affordable price. Specific gravities (SG) range from 1.3 to 8.
