Product Name：
PVC Profile Lead Salt Stabilizer YQ102 with Excellent Thermal Stability

Special Instruction:

Product Introduction：

1. Product Overview：
YQ102 is a high-performance lead-based stabilizer specifically engineered for PVC extrusion products. With a lead content of 26–28% and a unique composite formulation containing tribasic lead sulfate, auxiliary stabilizers, lubricants, and fillers, it delivers exceptional thermal stability, excellent whiteness, and outstanding processing performance. This stabilizer is widely used in PVC/WPC foam boards, profiles, pipes, wall boards, flooring, and other rigid extrusion applications where high whiteness and efficient stabilization are essential.

2. Product Principle：
YQ102 functions through the synergistic action of tribasic lead sulfate and auxiliary stabilizers. During PVC processing, the lead component rapidly neutralizes hydrogen chloride released by thermal degradation, forming stable lead chlorides that prevent catalytic decomposition of the polymer. The auxiliary stabilizers and lubricants enhance the stabilizing efficiency, promote uniform fusion, and improve melt flow. The filler component contributes to cost-effectiveness and dimensional stability. This multi-component system ensures excellent initial color hold, long-term thermal stability, and protection against discoloration and embrittlement, even under demanding extrusion conditions.

3. Performance Characteristics：
YQ102 delivers outstanding thermal stability with a melting point of 96–102°C and a volatile content of 1.8%, ensuring clean processing with minimal smoke or plate-out. The white flake form disperses readily in PVC compounds, promoting uniform stabilization throughout the melt. Its excellent thermal stability allows for lower dosage compared to conventional stabilizers, reducing formulation costs while maintaining superior performance. The stabilizer significantly improves whiteness, making it ideal for white and light-colored products. It also reduces the frequency of mold removal, improving production efficiency and reducing downtime. The product meets fire safety requirements, producing carbon monoxide when burned but no radioactive substances.

4. Usage and Dosage：
Recommended addition level is 3–5% based on total PVC formulation weight. For standard PVC extrusion products such as pipes, profiles, and boards, 3.5–4.5% typically provides optimal thermal stability and processing performance. For high-whiteness foam boards and flooring, dosages toward 5% are recommended to achieve superior color and surface quality. Systematic trials should be conducted to fine-tune the dosage for specific equipment, formulations, and performance requirements.

Product Advantages:

1. Excellent Thermal Stability with Lower Dosage
YQ102 provides superior thermal stability, allowing manufacturers to use lower addition levels compared to conventional stabilizers. This reduces formulation costs while maintaining excellent processing performance and product quality.

2. Outstanding Whiteness for Premium Products
The stabilizer significantly improves the whiteness of PVC products, making it ideal for white and light-colored foam boards, profiles, and flooring. Products exhibit bright, uniform surfaces without yellowing or discoloration.

3. Improved Processing Performance
YQ102 enhances the processing performance of PVC compounds by promoting uniform fusion and melt homogeneity. It reduces melt viscosity, improves flow characteristics, and ensures consistent extrusion with fewer defects.

4. Reduced Mold Removal Frequency
The excellent thermal stability and lubricating properties of YQ102 reduce the frequency of mold removal and cleaning. This improves production efficiency, reduces downtime, and extends equipment service life.

5. Enhanced Surface Quality and Appearance
Products stabilized with YQ102 exhibit smooth, high-gloss surfaces free from die lines, rough spots, or discoloration. This enhances the aesthetic appeal and market competitiveness of finished goods.

6. Cost-Effective Formulation
The composite formulation includes lubricants and fillers that reduce the need for additional additives. This simplifies formulations, lowers raw material costs, and improves overall production economics.

7. Wide Application Range
YQ102 performs effectively in a wide range of PVC extrusion products, including foam boards, profiles, pipes, wall boards, and flooring. It adapts to both single-screw and twin-screw extrusion lines.

8. Reliable and Consistent Performance
With controlled lead content (26–28%) and low volatiles (1.8%), YQ102 delivers consistent, reproducible stabilization across production runs. This ensures uniform product quality and reduces scrap rates.

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. Meet fire will produce carbon monoxide, but won't produce radioactive substances.

Applications：

1. PVC/WPC Foam Boards
YQ102 is widely used in PVC and WPC foam board production, providing excellent thermal stability and high whiteness. It ensures uniform cell structure and smooth surfaces for furniture boards, advertising boards, and construction boards.

2. PVC Profiles
In PVC profile extrusion, YQ102 delivers superior thermal stability and surface quality. It is suitable for window profiles, door frames, decorative trim, and technical profiles.

3. PVC Pipes
For PVC pipes and fittings, YQ102 provides reliable stabilization and good lubricity, ensuring smooth internal and external surfaces, consistent wall thickness, and long-term durability.

4. PVC Wall Boards
In wall board applications, YQ102 enhances whiteness and surface finish, producing bright, clean panels suitable for interior and exterior construction.

5. PVC Flooring
For PVC flooring, including SPC and WPC flooring, YQ102 improves thermal stability, dimensional accuracy, and surface appearance. It ensures consistent color and mechanical properties.

6. Highly Filled PVC Extrusions
In formulations with high filler content, YQ102 improves filler dispersion and maintains mechanical strength, enabling cost-effective production without compromising quality.

7. White and Light-Colored Products
YQ102 is especially suitable for white and light-colored PVC products where high whiteness and color purity are essential. It prevents yellowing and ensures bright, uniform appearance.

8. High-Speed Extrusion Lines
For high-output production, YQ102 provides the thermal stability and processing performance needed to maintain quality at line speeds exceeding 20 m/min.
