PVC Granules for Plstic-Coated Wires

Key Advantages for Plastic-Coated Wire PVC Granules

Our specialized PVC granules are engineered to create a tough, weather-resistant sheath for plastic-coated wire applications. Designed to endure, our compound provides superior UV and weather resistance, preventing fading and cracking to ensure your fencing, balcony rails, and industrial mesh maintain their appearance and integrity for years.

Beyond aesthetics, we deliver outstanding mechanical protection with high abrasion and impact resistance. Our formulation ensures excellent adhesion to the galvanized wire, creating a seamless barrier against corrosion.

Available in a wide spectrum of stable colors, our granules combine long-term durability with visual appeal, all while offering superior processability for your production line.

Choose our PVC granules to build coated wire products that are as reliable as they are attractive.

Main Advantages:

1. Superior Weather & UV Resistance
The coating is the first line of defense against the elements. Emphasize that your granules are formulated with high levels of UV stabilizers and antioxidants to prevent cracking, fading, and brittleness caused by sun, rain, and extreme temperatures. This ensures a long service life for outdoor applications like fencing and balcony rails.

2. Excellent Mechanical Protection
The coating must be tough. Highlight:

High Abrasion Resistance: Protects against scrapes and wear during installation and use.
Good Impact Strength: Absorbs blows without cracking, maintaining the integrity of the underlying wire.
Tensile Strength and Elongation: Provides flexibility and resistance to stretching or deformation.

3. Enhanced Corrosion Protection
The PVC sheath acts as a barrier, shielding the galvanized steel wire from moisture, salt, and chemicals. Position your compound as a critical component in a complete anti-corrosion system.

4. Strong Adhesion
A crucial performance factor for manufacturers is ensuring the PVC coating bonds firmly to the galvanized wire during extrusion. This prevents peeling, delamination, and moisture ingress at the interface.

5. Aesthetic Flexibility & Color Consistency
Offer visual appeal. Your granules should provide:

Rich, Consistent Colors: A wide range of standard (green, black, white, brown) and custom colors.
Excellent Color Stability: Resistance to fading ensures the product looks new for longer.
Good Surface Gloss: A smooth, attractive finish that enhances curb appeal.

6. Processability
For your clients’ manufacturing efficiency, highlight excellent extrusion performance, which allows for a smooth, uniform coating thickness, high production speeds, and consistent output.

Property Category	Key Specification	Typical Value / Requirement	Importance for Wire Coating
