SPC Floor Impact Resistance Adjustment Plasticizing Processing Aid S620

Product Principle：
With high styrene polymer content (≥95%), S620 promotes uniform fusion and plasticization during SPC extrusion. It enhances melt strength and elasticity through molecular chain entanglement, enabling stable processing at high line speeds while increasing surface hardness and rigidity. The relatively low melting point (116°C) ensures rapid activation early in the extrusion process, providing consistent performance throughout the production run and preventing defects associated with incomplete fusion.

Performance Characteristics：
S620 delivers exceptional improvements in melt strength and hardness for SPC flooring applications. It enhances impact resistance through optimized plasticization and molecular reinforcement, typically improving Izod impact strength by 30-50%. The additive improves weather resistance, making SPC products suitable for various environmental conditions including UV exposure and temperature fluctuations. Low fugitive constituent (≤2%) ensures clean processing without plate-out, die buildup, or surface defects, enabling longer production runs and reduced maintenance downtime.

1. Enhanced Melt Strength for SPC Processing：
S620 significantly improves melt strength during SPC extrusion, enabling stable processing at higher line speeds while maintaining dimensional accuracy and surface quality. This allows manufacturers to increase productivity without compromising product quality, reducing production costs and improving throughput.

2. Increased Hardness and Surface Durability：
The additive enhances surface hardness and scratch resistance of SPC flooring, ensuring products withstand heavy foot traffic in commercial settings, furniture loads, and everyday wear without surface damage or indentation. Hardness improvements of 20-30% on the Shore D scale are typical, significantly extending product life.

3. Improved Weather Resistance：
S620 enhances the weather resistance of SPC products, making them suitable for applications exposed to varying environmental conditions such as sunlight, humidity, and temperature changes. Products maintain their mechanical properties and appearance even after prolonged outdoor exposure.

4. Optimized Impact Resistance：
Through improved plasticization and molecular reinforcement, S620 delivers superior impact resistance, preventing brittle failure during handling, installation, and service. This is particularly important for large-format SPC planks that may experience stress during transportation and installation.

5. Consistent Processing Performance：
With low fugitive constituent content and controlled particle characteristics, S620 ensures consistent processing performance across production runs. It minimizes variations in melt behavior, reducing scrap rates and ensuring uniform product quality.

1. SPC Flooring：
S620 is specifically engineered for SPC flooring production, where it enhances melt strength, hardness, and impact resistance to meet the demanding requirements of modern flooring applications. It ensures SPC planks and tiles maintain dimensional stability, resist indentation from furniture and heels, and provide long-lasting performance in both residential and commercial settings.

2. Rigid Core SPC Products：
In rigid core SPC products requiring maximum dimensional stability and surface durability, such as luxury vinyl tiles and planks, S620 delivers the necessary reinforcement and processing stability. It ensures click-lock systems maintain precise tolerances for easy installation and secure connections.

3. Non-Foaming PVC Boards：
For solid PVC boards in construction and industrial applications, including wall cladding, partitions, and work surfaces, S620 improves rigidity and surface hardness while maintaining excellent processing characteristics for consistent quality.

4. Dense PVC Profiles：
In dense profiles requiring high strength and weather resistance, such as outdoor trim, fencing, and decking components, S620 provides the enhanced properties needed for long-term performance in demanding environments exposed to sun, rain, and temperature variations.

5. Wear Layer Applications：
For SPC products with dedicated wear layers, S620 can be incorporated to enhance the hardness and scratch resistance of the surface layer, providing additional protection against abrasion and maintaining aesthetic appeal throughout the product life.
