PVC Foaming Product Toughening Agent NCR61

Product Principle：
NCR61 features a unique core-shell copolymer structure combining styrene, methyl methacrylate, and butyl acrylate in optimized proportions. This advanced morphology disperses uniformly within the PVC foam matrix during processing, creating a reinforcing network that strengthens cell walls without interfering with cell formation or foam expansion. The core-shell structure effectively absorbs and dissipates impact energy throughout the material while preserving the thermal properties of the base polymer, ensuring no degradation in heat resistance.

Performance Characteristics：
Unlike traditional toughening agents that typically reduce heat resistance by 3-8°C, NCR61 maintains the Vicat softening temperature while significantly improving impact strength by 40-60% and flexibility. The balanced monomer composition ensures optimal compatibility with PVC foam formulations. High fineness (≥98% through 40 mesh) guarantees rapid dispersion and consistent performance throughout the foam matrix, eliminating localized weak spots that could lead to premature failure.

1. Maintains Vicat Heat Resistance：
NCR61 uniquely enhances toughness without reducing the heat-resistant Vicat value, a critical advantage over conventional toughening agents like CPE. This preserves product performance in high-temperature applications such as roofing, outdoor furniture, and automotive components.

2. Superior Toughness Enhancement：
The advanced core-shell copolymer structure provides exceptional impact modification, absorbing and dissipating energy throughout the foam matrix while maintaining cell wall integrity. This results in foamed products that resist cracking, chipping, and brittle failure under mechanical stress.

3. Excellent Dispersion in Foam Matrices：
With high fineness (≥98% through 40 mesh) and optimized particle characteristics, NCR61 disperses rapidly and uniformly in PVC foam formulations. This ensures consistent toughening throughout the product without creating weak spots or stress concentration points that could compromise performance.

4. Preserves Foam Structure Quality：
Unlike some toughening agents that disrupt cell formation or cause cell coalescence, NCR61 reinforces cell walls while allowing proper foam development. This results in uniform cell structure, consistent density distribution, and optimal mechanical properties in the final foamed product.

5. Versatile Formulation Compatibility：
NCR61 exhibits excellent compatibility with various PVC foam formulations, including free-foam, Celuka, and co-extrusion processes. It works effectively with both chemical and physical foaming agents, providing formulation flexibility for manufacturers.

Packing: 25 kg/bag
Storage: Conventional storage
Processing: Valid for 2 years
Note: Store in cool, dry warehouse, avoid rain, moisture. When stored, it must be kept away from fire and heat sources, avoid exposure to sunlight, and prohibit direct contact with acids, alkalis, or mixing.

1. PVC Foam Boards：
NCR61 is ideal for PVC foam boards used in signage, construction, and displays, where enhanced toughness is required without sacrificing heat resistance. Boards modified with NCR61 withstand handling, cutting, and installation while maintaining dimensional stability under temperature variations.

2. Foamed Profiles：
In foamed profiles for trim, moldings, and decorative applications, NCR61 provides superior impact resistance while maintaining dimensional stability. Profiles maintain their shape and mechanical properties even when exposed to elevated temperatures during transportation or service.

3. Lightweight Foam Panels：
For lightweight foam panels in transportation, marine, and construction applications, NCR61 delivers the toughness needed for structural integrity while preserving the weight-saving benefits of foamed structures.

4. High-Temperature Foam Applications：
In applications exposed to elevated temperatures, such as automotive components, roofing materials, and industrial insulation, NCR61 ensures foamed products maintain both mechanical integrity and thermal resistance throughout their service life.

5. Foamed Core Pipes and Profiles：
For co-extruded products with foamed cores and solid skins, NCR61 provides the necessary toughness in the core layer while maintaining compatibility with skin materials for excellent interlayer adhesion.
