Calcium Zinc Stabilizer for PVC Marine Aquaculture Floats & Buoys

Product Core Advantages (Marine Float Special Formula)

1. Excellent Thermal Stability, Zero Yellowing Molding

Customized balanced internal and external lubrication system, perfectly adapting to high-speed injection and blow molding processes of PVC floats. It effectively inhibits PVC thermal decomposition at 160–180°C, ensures consistent bright color of floating balls, no yellow spots or black spots, and greatly improves product surface finish and qualification rate.

2. Super Strong Seawater & UV Weather Resistance

Different from ordinary PVC stabilizers, this marine-grade formula adds anti-UV and anti-corrosion factors. It resists saltwater erosion, strong ultraviolet radiation and temperature alternation. It effectively delays aging, brittleness and cracking of PVC floats, extending the service life of ocean aquaculture floats to 8–12 years.

3. 100% Lead & Cadmium Free, Full Export Compliance

Eco-friendly heavy-metal-free formula, fully compliant with EU RoHS, REACH, SGS and ISO9001 international standards. Zero environmental risks for exporting to Europe, Southeast Asia, Americas and other global markets, helping manufacturers eliminate trade barriers.

4. Good Compatibility & No Precipitation

Perfect compatibility with PVC resin, plasticizers and other additives. No blooming, no surface precipitation, no mold fouling during continuous mass production. It stabilizes production efficiency, reduces mold cleaning frequency, and lowers production costs.

Premium Lead-Free Calcium Zinc Stabilizer for PVC Ocean Floating Balls & Aquaculture Buoys

Our professional-grade calcium zinc stabilizer is specially formulated for PVC marine floating balls, aquaculture buoys, fish cage floats, and shellfish farming rafts. Designed to solve the core pain points of PVC float manufacturers, including high-temperature yellowing, seawater corrosion, UV aging, and export compliance risks. It delivers stable processing performance and ultra-long outdoor service life for all marine PVC float products.

Core Industry Pain Points We Solve

Marine PVC floats face extreme and complex working environments, which easily cause product defects and shortened service life. Traditional stabilizers fail to adapt to ocean farming scenarios:
  • High-temperature processing yellowing: PVC decomposes and discolors during injection and blow molding, resulting in uneven float color and defective finished products
  • Severe marine aging: Long-term exposure to strong sunlight and seawater immersion leads to brittleness, cracking, water leakage and float failure
  • Export compliance risks: Heavy-metal stabilizers cannot pass RoHS, REACH and other international environmental certifications, restricting global market sales
  • Surface precipitation & poor finish: Unmatched auxiliary formulas cause mold fouling, sticky surface and low product qualification rate

Applicable Scenarios

  • PVC marine aquaculture floating balls (30cm/50cm/80cm/100cm)
  • Ocean fish cage floating buoys and frame floats
  • Oyster, scallop and shellfish farming floating rafts
  • Marine aquaculture area isolation floats and warning buoys
  • Outdoor water engineering PVC floating bodies

Frequently Asked Questions

Q1: Is this stabilizer suitable for all PVC floating ball production processes?

Yes. It is perfectly adapted to injection molding, blow molding and extrusion processes of PVC floats, with a wide processing window and stable performance for mass continuous production.

Q2: Can it solve the problem of float yellowing after long-term sea exposure?

Absolutely. The marine-specific formula contains high-efficiency anti-UV and anti-aging components, which fundamentally improve the weather resistance of PVC floats and avoid yellowing and fading caused by long-term marine exposure.

Q3: Does it support customized formulas for special float products?

Yes. We provide personalized formula customization for high-transparency floats, super weather-resistant floats and special-scene marine floating bodies to meet diverse production needs.

Q4: What is the delivery time and after-sales service?

Regular models: 3–7 working days; customized models: 7–15 working days. We provide one-stop technical support, including formula guidance and on-site production adjustment suggestions.
