Product Introduction：

1. Product Overview：
PM40 is a high-performance processing aid specifically developed for PVC WPC (Wood-Plastic Composite) and PVC SPC (Stone-Plastic Composite) product manufacturing. With an active content of 98%, it significantly improves the toughness and impact resistance of PVC composites while maintaining excellent processing characteristics. This additive is widely used in WPC decking, SPC flooring, wall panels, and other rigid composite profiles where mechanical strength, durability, and consistent quality are critical. PM40 enables manufacturers to reduce brittleness, enhance impact performance, and achieve reliable production in demanding indoor and outdoor applications.

2. Product Principle：
PM40 functions by promoting uniform fusion and plasticization of PVC resin within highly filled WPC and SPC formulations. Its high molecular weight structure intertwines with PVC chains, creating a reinforced network that effectively absorbs and dissipates impact energy. The additive enhances melt cohesion, improves filler dispersion, and strengthens interfacial bonding between the PVC matrix and wood flour or calcium carbonate fillers. This results in a tougher, more impact-resistant composite that resists cracking, chipping, and brittle failure under mechanical stress. The low volatile content ensures clean processing, while the controlled particle size guarantees rapid dispersion and consistent performance throughout the production run.

3. Performance Characteristics：
PM40 delivers outstanding performance with an active content of 98% and a granularity of ≤2%, ensuring efficient reinforcement at low dosage. The apparent density of 0.35 g/cm³ facilitates easy handling and uniform dispersion. Vdaf ≤1% guarantees clean processing with minimal smoke, odor, or plate-out. The additive significantly improves impact resistance and toughness without compromising rigidity or dimensional stability. PM40 also enhances surface finish, reduces defects, and improves the overall mechanical integrity of WPC and SPC products. Its balanced formulation ensures compatibility with stabilizers, lubricants, foaming regulators, and other additives commonly used in composite extrusion.

4. Usage and Dosage：
Recommended addition level is 3–5% based on total formulation weight. For standard WPC and SPC applications requiring moderate toughness improvement, 3–4% typically provides optimal results. For high-impact applications such as heavy-duty decking, industrial flooring, or outdoor structural profiles, dosages toward 4–5% are recommended. Systematic trials should be conducted to fine-tune the dosage for specific formulations, equipment, and performance requirements.

Product Advantages:

1. Significant Toughness and Impact Resistance Enhancement
PM40 substantially improves the toughness and impact resistance of PVC WPC and SPC products. It absorbs and dissipates impact energy, preventing brittle failure and ensuring long-term durability in demanding applications such as decking, flooring, and outdoor profiles.

2. Improved Filler Dispersion and Interfacial Bonding
PM40 enhances the dispersion of wood flour, calcium carbonate, and other fillers within the PVC matrix. It strengthens interfacial bonding between the polymer and fillers, resulting in more uniform properties, reduced internal stress, and improved overall composite integrity.

3. High Active Content for Cost-Effective Performance
With 98% active content, PM40 delivers maximum reinforcement effect per unit weight. This allows manufacturers to achieve significant toughness improvement at low dosage, reducing formulation costs while maintaining high product quality.

4. Clean Processing with Minimal Plate-Out
Low volatile content (Vdaf ≤1%) ensures clean processing with minimal smoke, odor, or die buildup. This enables longer production runs, reduced cleaning downtime, and consistently high surface quality.

5. Enhanced Melt Strength and Processing Stability
PM40 improves melt strength and elasticity, stabilizing the extrusion process and reducing melt pulsation. This enables consistent product dimensions, higher line speeds, and fewer processing defects.

6. Improved Surface Quality and Appearance
PM40 promotes smoother melt flow and reduces surface defects, producing WPC and SPC products with excellent surface finish. This is particularly valuable for visible applications such as flooring, wall panels, and decorative profiles.

7. Excellent Dispersion and Compatibility
PM40 disperses readily in PVC compounds, ensuring uniform distribution throughout the melt. Its excellent compatibility with PVC resins, stabilizers, lubricants, and foaming regulators simplifies formulation development and ensures consistent product quality.

8. Versatile Across WPC and SPC Applications
PM40 performs effectively in a wide range of WPC and SPC products, including decking, fencing, flooring, wall panels, and profiles. Its balanced formulation provides formulation flexibility and simplifies inventory management.

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. When mixed with strong oxidants, it may burn under high temperature and release carbon dioxide.

Applications：

1. PVC WPC Decking and Fencing
PM40 is widely used in WPC decking and fencing production, providing exceptional impact resistance and toughness for outdoor applications exposed to heavy foot traffic, moisture, and UV radiation.

2. PVC SPC Rigid Core Flooring
In SPC flooring formulations, PM40 enhances toughness and crack resistance, ensuring planks and tiles withstand installation stresses and daily wear without chipping or breaking.

3. PVC WPC Wall Panels and Cladding
For WPC wall panels, PM40 improves dimensional stability, surface quality, and impact resistance, ensuring long-lasting performance and aesthetic appeal in interior and exterior applications.

4. PVC WPC Profiles and Trim
In WPC profiles, PM40 enhances melt strength and processing stability, enabling consistent dimensions and high-quality surfaces for decorative and functional profiles.

5. PVC WPC Furniture Components
For WPC furniture components, PM40 provides the toughness and durability needed for load-bearing applications, reducing the risk of cracking or failure during assembly and use.

6. High-Filled PVC Compounds
In formulations with high filler content, PM40 improves filler dispersion, melt strength, and mechanical performance, enabling cost-effective production without sacrificing quality.

7. Co-extruded WPC/SPC Products
For co-extruded products with cap layers or decorative surfaces, PM40 ensures the rigid core maintains structural integrity and impact resistance without affecting interlayer adhesion.

8. Outdoor WPC Applications
PM40 is ideal for outdoor WPC products exposed to environmental stress, providing long-term durability and resistance to impact, moisture, and temperature fluctuations.
