As a new generation of azodicarbonamide-based foaming agents, the NC white foaming agent brings breakthrough processing advantages and quality improvements to PVC product production through its innovative low-temperature foaming characteristics. It has become the preferred material for high-end foamed products.

Innovative Technical Features:

Low-Temperature Activation Advantages

• Decomposition temperature reduced to the range of 165-185°C, 10-20°C lower than traditional foaming agents

• Effectively avoids resin degradation caused by high temperatures, maintaining material performance integrity

• Particularly suitable for heat-sensitive formulations and low-temperature processing technologies

Excellent Foaming Performance

• Gas yield reaches 200-220 ml/g, with nitrogen-dominated foaming gas ensuring stability

• Forms a uniform closed-cell structure of 50-200 μm, with a closed-cell rate exceeding 92%

• Density can be reduced to 0.5-0.7 g/cm³, achieving significant lightweight effects

Color Retention Technology

• Unique white decomposition residues, perfectly compatible with the PVC matrix

• Completely solves the problem of product yellowing, improving whiteness retention by over 30%

• Especially suitable for applications with strict color requirements, such as medical and food packaging

Enhanced Application Value:

• Broadened processing window, increasing production efficiency by 20-30%

• Energy consumption reduced by 15-25%, meeting green manufacturing requirements

• Dosage reduced by 15-20%, with significant comprehensive cost-effectiveness

• Fully complies with EU RoHS and REACH environmental standards

Process Adaptation Guidelines:

• Recommended dosage: 0.8-2.5 phr (adjustable based on density requirements)

• Optimal activation system: zinc-based composite activator (dosage: 0.2-0.5 phr)

• Temperature control range: 170-190°C (±5°C)

• Suitable for various processes, including free foaming, skin foaming, and compression molding foaming

The NC white foaming agent offers an innovative solution for PVC foamed products through its advanced low-temperature foaming technology and exceptional color retention capabilities. It demonstrates significant application value in industries with stringent requirements for processing temperature and product appearance, including medical devices, food packaging, and high-end building materials.
