Product Name：
PVC Extrusion and Soft Products ECO-Friendly Ammonia-Free Blowing Agent C2

Special Instruction:

Product Introduction：

1. Product Overview：
C2 is an environmentally friendly, ammonia-free blowing agent specifically designed for PVC extrusion and soft PVC products. It effectively reduces product density and improves cell structure while serving as a sustainable alternative to conventional AC and NC foaming agents. This makes it ideal for manufacturers seeking to meet stringent environmental regulations without compromising foaming performance or product quality. C2 is particularly suitable for PVC foam boards, profiles, sheets, and soft PVC applications where consistent cell structure and smooth surfaces are essential.

2. Product Principle：
C2 decomposes within the temperature range of 140–165°C, releasing inert gas that forms uniform cells throughout the PVC matrix. Its ammonia-free composition eliminates unpleasant odors and potential health hazards associated with traditional blowing agents that release ammonia during decomposition. The controlled gas release mechanism ensures consistent cell nucleation and growth, resulting in a fine, homogeneous foam structure with excellent surface quality and dimensional stability. The gas formation volume of ≥120 ml/g provides efficient expansion for meaningful density reduction.

3. Performance Characteristics：
With a gas formation volume of ≥120 ml/g, C2 delivers efficient foaming while maintaining low residual content in the final product. The narrow decomposition temperature window allows for precise control during processing, enabling manufacturers to optimize cell structure for specific applications. Low water content (≤1%) and minimal residue on sieve (0.1%) ensure clean decomposition without causing surface defects, plate-out, or die buildup during extended production runs. Its eco-friendly profile meets global standards for sustainable manufacturing and green building certifications.

4. Usage and Dosage：
Recommended addition level is 0.5–4% based on total formulation weight, depending on desired density reduction and foam structure requirements. For soft PVC products such as flexible sheets and profiles, lower dosages around 0.5–1.5% are typical to maintain flexibility while achieving moderate weight reduction. For extruded rigid profiles requiring significant density reduction, higher dosages toward 2–4% may be employed. Optimal dosage should be determined through trials to achieve target foam quality, cell uniformity, and mechanical property retention.

Product Advantages:

1. Environmentally Friendly and Ammonia-Free
C2 contains absolutely no ammonia or ammonia-releasing compounds, completely eliminating unpleasant odors and potential respiratory health concerns during processing. It fully complies with modern environmental regulations including REACH, RoHS, and various green building standards, making it suitable for eco-conscious manufacturers and sustainable product lines targeting environmentally aware consumers.

2. Direct Replacement for AC and NC Agents
C2 can seamlessly replace conventional AC and NC foaming agents without major formulation adjustments or equipment modifications. It offers comparable or superior foaming performance while dramatically reducing environmental impact. Manufacturers can transition to this eco-friendly alternative with minimal disruption to existing production processes.

3. Uniform Cell Structure and Superior Surface Quality
The controlled, consistent decomposition of C2 produces fine, evenly distributed cells throughout the product cross-section. This uniformity enhances foam structural integrity, improves mechanical properties, and results in smoother surfaces free from visible defects. The improved surface quality is particularly valuable for products requiring painting, lamination, or direct visual appeal.

4. Wide Processing Window and Versatility
With a decomposition temperature range of 140–165°C, C2 accommodates various processing conditions and equipment types, including single-screw and twin-screw extruders, injection molding machines, and compression molding presses. It provides exceptional flexibility in extrusion and molding operations without compromising foam quality or requiring frequent parameter adjustments.

5. Clean Processing and Extended Production Runs
Low fugitive constituent content and minimal residue ensure clean decomposition without causing die buildup, plate-out, or surface contamination. This enables longer uninterrupted production runs, reduced maintenance downtime, and consistently high product quality throughout extended manufacturing campaigns.

6. Efficient Density Reduction at Low Dosage
With a gas formation volume of ≥120 ml/g, C2 achieves significant weight reduction at relatively low addition levels. This makes it a cost-effective solution for manufacturers seeking to reduce material consumption while maintaining product performance and appearance.

7. Excellent Compatibility with PVC Formulations
C2 disperses readily in PVC compounds and exhibits excellent compatibility with stabilizers, lubricants, processing aids, and other additives. This simplifies formulation development and ensures consistent foaming performance across a wide range of PVC applications.

8. Suitable for Soft and Rigid PVC Products
C2 performs effectively in both soft and rigid PVC foaming applications, including flexible sheets, profiles, foam boards, and extruded articles. Its balanced decomposition profile ensures consistent results regardless of product thickness or processing method.

Applications：

1. PVC Extruded Profiles
C2 is ideal for extruded PVC profiles requiring weight reduction and uniform cell structure, such as decorative trim, architectural moldings, and construction components where both lightweight properties and aesthetic appearance are essential.

2. Soft PVC Products
In soft PVC applications including flexible hoses, weatherstripping gaskets, cushioning sheets, and expanded vinyl flooring, C2 delivers fine, closed-cell foam structures while maintaining flexibility, resilience, and surface softness.

3. PVC Foam Boards
For lightweight foam boards used in signage, point-of-purchase displays, exhibition panels, and furniture components, C2 provides consistent density reduction and exceptionally smooth surfaces suitable for high-quality digital printing, paint adhesion, and film lamination.

4. Sustainable Product Lines
Manufacturers developing eco-friendly product lines for green building projects, environmentally certified furniture, or sustainable consumer goods will benefit significantly from C2's ammonia-free formulation and compliance with stringent environmental standards.

5. Cable and Wire Insulation
In foamed cable insulation and wire jacketing applications, C2 contributes to weight reduction and improved dielectric properties while maintaining the flexibility and durability required for electrical applications.

6. PVC Sheets and Panels
For rigid and semi-rigid PVC sheets used in construction, advertising, and industrial applications, C2 enables controlled foaming with uniform cell structure and smooth surfaces suitable for printing, lamination, and finishing.

7. PVC Pipe and Profile Foaming
In PVC pipes and profiles where weight reduction and insulation properties are desired, C2 enables controlled foaming with uniform cell structure and excellent surface quality, reducing material consumption without compromising performance.

8. General PVC Foaming Applications
C2 is suitable for a wide range of general PVC foaming applications, offering a sustainable, high-performance alternative to conventional blowing agents while maintaining consistent quality and processing reliability.
