Manufacturing Process
PVC Balls are CNC-machined from extruded rigid PVC rod stock. Grey PVC (chlorinated or standard) offers different chemical resistance profiles — specify application for grade selection.
Compliance & Standards
IEC registered. ISO 3290 Grade G10. Flame retardant — self-extinguishing UL94 V-0. Note: PVC is limited to +60°C maximum service temperature. For higher temperature or FDA food-grade applications, PP, HDPE, or PTFE Balls are recommended. Regular export to UAE, Germany, USA, Japan, Singapore, Brazil, Turkey, and Middle East.
Frequently Asked Questions
What is the largest PVC Ball you manufacture?
We manufacture rigid PVC Balls up to 310mm diameter — one of the widest size ranges for PVC Balls available globally. Large PVC Balls serve large-bore water treatment check valves and chemical plant piping check valves.
What chemicals are PVC Balls resistant to?
Rigid PVC Balls resist inorganic acids (hydrochloric, sulfuric, phosphoric), alkalis, chlorine, brine solutions, and most inorganic chemicals. Not recommended for THF, cyclohexanone, and concentrated sulfuric acid — use PTFE or PVDF Balls for aggressive solvent or concentrated acid service.
Are PVC Balls flame retardant?
Yes. Rigid PVC Balls are inherently flame retardant — self-extinguishing per UL94 V-0. This makes them suitable for chemical plant and water treatment applications where flame retardancy is a requirement.
