PVC foaming regulator for board is a key auxiliary agent used to improve the processing performance and product quality of PVC foam board. Its main function is to regulate melt elasticity and cell structure. This type of regulator is usually an acrylic polymer (ACR) with a molecular weight between 80,000 and 150,000. It stabilizes the foaming process by enhancing the melt strength to form a uniform and fine cell structure (100-300μm).
In the production of PVC foam board, the core functions of ACR foaming regulator include: improving the melt elastic modulus to prevent bubble rupture, promoting uniform nucleation to form fine cells, and enhancing the cell wall strength to prevent collapse. It needs to be used with AC foaming agent to control the foaming effect by adjusting the decomposition temperature (160-200℃).
High-quality PVC foaming regulator for board can increase the uniformity of cells by more than 50%, and the density deviation is controlled within ±5%. When selecting, parameters such as foaming ratio and PVC board thickness should be considered. For example, high molecular weight ACR should be selected for high-ratio foaming. The current development trend includes innovative technologies such as core-shell structure design, reactive modification, and more environmentally friendly VOC-free formulas. The rational use of foaming regulators can make PVC foam board both lightweight and high-strength, and are widely used in architectural decoration, advertising panels and other fields.

Cell structure optimization
-Uniformity: The use of PVC foaming regulator for board can promote the formation of small, evenly distributed closed or open cell structures, and improve the mechanical properties of the sheets (such as compression resistance and impact resistance).
-Stability: The use of ACR foaming regulator for PVC sheets can prevent the cellular merging or collapse, and reduce shrinkage or deformation during the molding process.
Density control
-PVC foaming regulator for board can achieve lightweight (low density) or high strength (high density) requirements for sheets by adjusting the foaming ratio, balancing weight and performance.
Improved processing performance
- Compatibility: Foaming regulator for PVC sheets is well compatible with substrates (such as PVC, PP, PS, PU, etc.) and foaming agents (such as AC foaming agents) to avoid precipitation or reaction failure.
- Temperature adaptability: Match the processing temperature range (such as low temperature or high temperature foaming) to ensure that the foaming process is controllable.
Enhanced physical properties
- Insulation/sound insulation: closed-cell structure can improve thermal insulation performance (such as insulation board for construction).
- Mechanical strength: Use foaming regulator for PVC board to optimize the thickness of the cell wall and improve the rigidity, toughness or bending resistance of the board.
Environmental protection and safety
- Surface quality: Reduce surface defects (such as bubbles, roughness), improve aesthetics and subsequent processing (such as veneer, spraying).
- Low VOC: ACR foaming regulator for PVC board meets environmental protection standards and reduces volatile organic compound emissions.
- Non-toxic: The foaming regulator produced by our company is suitable for sensitive fields such as food packaging or medical (such as FDA standards).
Main applications of PVC foaming regulator in board production:
PVC free foam board
Regulator selection: ACR type (addition amount 3-8 phr).
Effect: The cells are independent and uniform, with a density of 0.5-0.7g/cm³, used for advertising display boards and partitions.
PVC crust foam board
Core requirements: high surface hardness + low density core layer.
Regulator solution: ACR + nano-CaCO₃ (1-3 phr), forming a dense skin layer (density gradient structure).
Imitation wood grain PVC foam board
- Special requirements: clear surface texture, high fluidity regulator (such as low molecular weight ACR) is required
Others
- Widely applicable: Foaming regulator for PVC board is suitable for many other boards, such as PVC foam wallboard; PVC wood-plastic board; polystyrene board, etc.
- Multi-industry application: widely used in architectural decoration, furniture, packaging and automotive interior.
PVC foaming regulator is a high molecular weight acrylic ester additive used to adjust the quality of PVC foaming, and its molecular weight is usually between 5 million and 6.5 million. It improves the melt strength and fluidity of PVC foam products by adjusting the foaming quality and density, ensuring the uniform distribution of bubbles and preventing bubble merging. The main functions of the foaming regulator include: accelerating the melt adhesion of PVC, reducing the processing temperature, increasing the surface cleanliness of the board material, and improving the mechanical properties of the material.
PVC foam board, the term implies a unique material technology. It is not just a board, but also an innovative product that combines modern chemistry and physical technology. PVC, or polyvinyl chloride, is a plastic material widely used in many fields such as construction, home furnishing, and packaging. And foaming technology gives PVC product materials new vitality.
Imagine that when PVC product materials are added with specific foaming regulators, countless tiny pores are formed inside. These pores not only make the material light, but also give it excellent sound insulation and heat insulation properties. This is PVC foam board, a light and powerful material. It not only inherits the durability, moisture resistance and fire resistance of PVC, but also has excellent performance in heat preservation and sound insulation.
PVC foaming regulator is added according to the product formula ratio (such as resin, plasticizer, stabilizer, etc.), stirred and heated by a mixer, fully mixed and evenly processed, and can be adjusted and used according to specific product requirements and processes.
PVC foaming regulator is a non-toxic, non-corrosive solid powder, and is transported as a non-hazardous item. It should be avoided from sunlight and rain, and it is recommended to be stored in a cool and ventilated place indoors. The storage period is 1 year, and it can be used if there is no change in performance test. The packaging is generally 25 kg/bag, which can be customized according to customer requirements.
