PVC SPC and Non-Foaming Profile Products Special Ca/Zn Heat Stabilizer CZ758

Product Name：
PVC SPC and Non-Foaming Profile Products Special Ca/Zn Heat Stabilizer CZ758

Special Instruction:

Product Introduction：

1. Product Overview：
CZ758 is a highperformance calciumzinc heat stabilizer engineered for PVC SPC and nonfoaming product production. With ≥99% active substance, it delivers excellent thermal stability, good lubricity, and a unique coupling effect for dimensionally stable, highquality extrusions.

2. Product Principle：
Zinc stearate provides initial color hold; calcium stearate ensures longterm stability by neutralizing HCl. Auxiliary lubricants reduce friction, and the coupling effect improves fillerresin adhesion, enhancing dispersion and mechanical strength. Melting at 105°C ensures early activation.

3. Performance Characteristics：
CZ758 offers clean processing (volatiles ≤2%), easy dispersion (density 0.35 g/cm³), good lubricity that reduces equipment wear, and a unique coupling effect for superior filler dispersion, surface brightness, and dimensional accuracy in highly filled SPC formulations.

4. Usage and Dosage：
Recommended addition: 3–5 phr. For standard SPC (200–300 phr CaCO₃), use 3.5–4.5 phr; for highspeed lines or recycled content, use toward 5 phr. Optimize via trials.

Product Advantages:

1. Exceptional Thermal Stability：
Prevents degradation, edge browning, and surface defects at high line speeds (20–30 m/min) and with recycled material.

2. Good Lubricity & Reduced Equipment Wear：
Lowers extrusion torque and energy consumption, extending screw/barrel life and reducing maintenance.

3. Unique Coupling Effect for Filler Dispersion：
Improves bonding between PVC and CaCO₃, boosting flexural strength, impact resistance, and reducing brittleness in highly filled formulas (250–300 phr).

4. Enhanced Surface Brightness & Aesthetic Quality：
Produces smooth, highgloss surfaces free from die lines or fisheyes, reducing finishing costs.

5. Environmentally Friendly & Heavy Metal Free：
Complies with RoHS, REACH, FloorScore, and GREENGUARD for ecofriendly SPC products.

6. Improved Dimensional Control：
Early activation and uniform melt viscosity reduce shrinkage and warpage, ensuring tight tolerances (≤0.05 mm) for clicklock assembly.

7. Prolonged Equipment Service Life：
Reduced mechanical wear lowers capital replacement costs and increases uptime.

8. Versatile for NonFoaming PVC Products：
Works in rigid sheets, profiles, pipes, and calendered films on single or twinscrew extruders.

General instructions:

Packing: 25 kg/bag
Storage: Conventional storage
Processing: Valid for 2 years
Note: Store in a cool, dry warehouse away from heat, sunlight, moisture, and incompatible substances like strong oxidants or acids.

Applications:

1. PVC SPC Rigid Core Flooring：
Preferred stabilizer for SPC planks/tiles, delivering thermal stability, low shrinkage, excellent filler dispersion, and tight tolerances for clicklock profiles.

2. PVC NonFoaming Sheets & Panels：
For rigid sheets in construction, signage, and industry – provides clean processing, high gloss, and uniform stabilization without warping.

3. PVC Rigid Profiles (Window Trim, Skirting)：
Ensures smooth surfaces, dimensional accuracy, and longterm weatherability with low die buildup.

4. PVC Pipes & Conduits (NonPressure)：
Reliable stability and lubricity for electrical conduits, drainage pipes, and cable ducts, improving internal surface smoothness.

5. Highly Filled PVC Extrusions (>200 phr filler)：
Coupling effect maintains mechanical strength and prevents melt fracture at high filler loadings.

6. Coextruded Rigid PVC Products：
Stabilizes the rigid core without affecting interlayer adhesion or causing outgassing delamination.

7. Recycled PVC NonFoaming Extrusions：
Stabilizes impurities, enabling up to 30% reclaim content while preserving surface finish and mechanicals.

8. Calendered Rigid PVC Films：
Provides early activation and clean release for blemishfree films with excellent gloss (e.g., credit cards, stationery).
