PVC Foaming and Non-foaming Profiles Tempering Agent PM40

Product Principle：
PM40 functions by modifying the morphological structure of PVC during processing. It promotes uniform dispersion and creates a fine, homogeneous morphology that effectively dissipates impact energy throughout the material rather than allowing stress concentration at weak points. In foaming applications, it stabilizes cell structure while improving wall integrity, preventing cell coalescence and collapse. The tempering effect reduces internal stresses that can lead to cracking and premature failure, while the molecular structure enhances chain entanglement for improved mechanical properties.

Performance Characteristics：
PM40 delivers comprehensive toughness improvement across both foaming and non-foaming applications. It significantly enhances impact resistance, with typical improvements of 40-60% in notched impact strength, and prevents brittle fracture under stress. The additive improves crack initiation and propagation resistance, extending product service life by 2-3 times in cyclic loading applications. It enhances processing stability by improving melt strength and reducing pulsation, allowing for wider processing windows and higher production speeds. With 98% active content and controlled particle size (≤2% granularity), it ensures efficient, consistent performance with rapid dispersion and minimal waste.

Usage and Dosage：
Addition: 4–12% of total formulation.

Foaming: 6–10% (stable cell structure, balanced properties)

Non-foaming: 10–12% (max toughness & impact resistance)

Optimal dosage determined by formulation and trials.

1. Dual Application Versatility：
PM40 performs effectively in both foaming and non-foaming PVC profiles, simplifying inventory management and formulation development. Manufacturers can stock a single additive for multiple product lines, reducing complexity and purchasing costs. Its adaptable nature ensures optimal performance across diverse applications without the need for application-specific variants.

2. Comprehensive Toughness Improvement：
The additive enhances multiple toughness parameters simultaneously, including impact resistance, crack resistance, and flexibility. This comprehensive approach ensures products withstand various failure mechanisms including sudden impact, slow crack growth, and cyclic fatigue. The result is products that remain reliable throughout their intended service life under real-world conditions.

3. Brittleness Reduction and Durability Enhancement：
PM40 significantly reduces brittleness in PVC products, making them more resilient to handling, installation, and in-service stresses. This extends product life and reduces failure rates in applications ranging from construction to furniture. The reduced brittleness also improves safety by eliminating sharp fracture surfaces that could cause injury.

4. Processing Stability Improvement：
By enhancing melt strength and reducing pulsation, PM40 improves processing stability and consistency. This reduces scrap rates by 15-25% in typical production environments and enables higher production speeds without quality compromise. The improved stability also means less operator intervention and more consistent product quality throughout production runs.

1. PVC Foaming Profiles：
In foaming profiles such as foam boards, trim, and decorative moldings, PM40 improves cell wall integrity while enhancing overall toughness. It ensures foamed products maintain mechanical performance despite reduced density, with uniform cell structure that provides consistent properties throughout. The enhanced melt strength also improves foam quality and reduces density variation.

2. PVC Non-foaming Profiles：
For solid profiles requiring maximum durability in demanding applications such as industrial components, transportation, and heavy construction, PM40 provides comprehensive toughness enhancement and crack resistance. This ensures reliable performance under continuous load, impact, and environmental stress.

3. PVC Window and Door Profiles：
PM40 improves the impact resistance and weatherability of window and door profiles, reducing the risk of damage during installation and service while extending product life. The enhanced toughness is particularly valuable in corners and welded joints where stress concentrates and failure often initiates.

4. PVC Construction Profiles：
In construction applications where durability is critical, such as roofing components, siding, and structural elements, PM40 ensures profiles maintain structural integrity under mechanical stress and environmental exposure. The improved crack resistance prevents failure initiation at notches, cuts, and attachment points.
