Calcium zinc stabilizer

Parameter

Performance Characteristics

PVC stabilizers for wall panels/carbon crystal boards must not only meet the basic requirements of general PVC stabilizers – such as thermal stability, compatibility, and dispersibility – but also possess the following characteristics tailored to the application scenarios and performance demands of panel products:

1. High-Temperature Stability

• Processing Adaptability: Products like carbon crystal boards often require high-temperature extrusion or lamination processes (temperatures reaching 180-220°C). The stabilizer must remain stable under these conditions, inhibiting PVC dehydrochlorination (HCl generation) to prevent panel yellowing and cracking.
• Long-Term Heat Resistance: When used in interior decoration near heat sources (e.g., underfloor heating, appliances), the stabilizer must provide sustained thermal resistance to prevent aging and decomposition during use.

2. Surface Finish & Decorative Quality

• Low Plate-Out/Migration: Prevents the stabilizer from migrating to the panel surface, which could impair the adhesion of subsequent processes like laminating, printing, or coating, thereby avoiding issues like bubbles, delamination, or uneven gloss.
• Impurity Control: Low impurity content and high purity are essential to prevent the formation of black specks or "fish eyes" during processing, ensuring a smooth, flawless panel surface, especially critical for high-gloss or skin-touch finishes.

3.Synergistic Enhancement of Mechanical Properties

• Melt Strength Optimization: Improves PVC melt uniformity, reduces weld lines during extrusion, and enhances panel rigidity (e.g., resistance to bending deformation) and toughness (impact resistance), meeting the mechanical demands of wall installation.
• Filler Compatibility: Fillers like calcium carbonate are often added to reduce costs. The stabilizer must work synergistically with fillers to prevent agglomeration, which would otherwise compromise mechanical properties.

4. Weather & Aging Resistance

• UV Resistance: For use in sun-exposed areas (e.g., balconies, bay windows), the stabilizer needs to be combined with UV stabilizers (e.g., organotins, complex stabilizers) to delay panel fading and chalking.
• Moisture & Heat Resistance: In high-humidity environments (e.g., kitchens, bathrooms), the stabilizer must inhibit hydrolysis reactions to prevent panel swelling and delamination.
• By precisely matching stabilizer performance with product processing requirements, the appearance quality, durability, and environmental performance of PVC wall panels/carbon crystal boards can be effectively enhanced.

Application Fields

1、Residential Renovation:

• Living Room & Bedroom Wall Decoration: PVC wall panels and carbon crystal boards are commonly used for feature walls like TV accent walls in living rooms or headboard walls in bedrooms. The stabilizer ensures the panels resist daily sunlight exposure and temperature fluctuations during long-term use, preventing discoloration and deformation while maintaining aesthetics.
• Kitchen & Bathroom Wall Cladding:

2、Commercial Spaces:

• Office Partitions & Wall Decor: Using PVC panels and carbon crystal boards for space dividers and wall decoration. Incorporating the stabilizer ensures the panels resist aging and fading during prolonged use in office environments, maintaining corporate image.
• Retail Store Fit-outs: For wall cladding in stores (e.g., clothing shops, restaurants). Panels with stabilizer can adapt to varying indoor conditions, are easy to clean and maintain, and help create comfortable shopping and dining environments.

3、Public Facilities:

• Interior Renovation for Hospitals & Schools: These venues have stringent environmental requirements. Stabilizers used in the panels (e.g., calcium-zinc stabilizers) must comply with environmental standards, ensuring panel performance while guaranteeing no harm to human health.
• Hotel Lobbies & Corridors: Wall panels require excellent weather resistance and stability to withstand high foot traffic and diverse environmental factors. The stabilizer enables PVC panels/carbon crystal boards to maintain long-term appearance and performance stability, reducing maintenance costs.
