Key Features
- The Food-Grade Silicone Rubber Ball is designed for hygienic processing where material purity and thermal stability are non-negotiable:
- Uncompromising Food Safety - Platinum-cured formulation eliminates peroxides and volatile byproducts; fully compliant with FDA, LFGB, and BfR for direct food contact.
- Extreme Temperature Tolerance - Functions reliably in frozen-food lines at −60°C and in hot-fill, baking, or sterilization processes up to 230°C, far beyond the range of conventional elastomers.
- Zero Flavor or Odor Transfer - Organoleptically neutral silicone preserves the original taste, aroma, and appearance of beverages, dairy, pharmaceuticals, and cosmetics.
- Hygienic & Bio-Inert - Non-porous surface resists bacterial adhesion and biofilm formation, simplifying CIP/SIP cleaning and supporting sterile production.
- Durable Elasticity - High tear strength and low compression set ensure consistent sealing force through millions of open-close cycles in check valves and pump seats.
- Tailored Specification - Hardness from 20 to 80 Shore A, translucent or colored options, and precision diameters to match OEM equipment exactly.
Common Applications
- Beverage & Dairy Processing - Sealing balls in filling valves, diaphragm pumps, and aseptic carton machines for milk, juice, beer, and soft drinks.
- Food Processing & Baking - Check-valve balls and discharge spheres in dough pumps, sauce dispensers, and hot-fill equipment.
- Pharmaceutical & Medical - Precision balls in dosing pumps, sterile filters, and laboratory fluid-handling devices requiring biocompatibility.
- Cosmetics & Personal Care - Sealing and metering balls for lotion, cream, and perfume filling lines where purity and color stability matter.
- Household Appliances - Sealing balls in coffee machines, water purifiers, steam ovens, and baby-food processors.
- Pet & Animal Care - Non-toxic balls for pet feeders, waterers, and veterinary equipment.
Quality Assurance
- Every lot is tested for dimensional accuracy, hardness, and compression set before release.
- Full batch traceability and compliance certificates (FDA, LFGB, BfR) available on request.
- OEM/ODM support with custom packaging and private-label options.
