PVC foaming regulator for profile is a type of acrylic processing aid. In addition to having all the characteristics of PVC processing aids, the PVC profile foaming regulator produced by our factory has a much higher molecular weight than general processing aids, has a higher melt strength, can give the product a more uniform pore structure and lower density, prevent pore merging or collapse, form a fine, uniform closed-cell structure, enhance the elasticity and ductility of the PVC melt, avoid gas escape or bubble breaking, optimize mechanical properties (such as impact resistance, hardness), and reduce surface defects (such as cracks, roughness).PVC foaming regulator for profile is suitable for lightweight and high-demand scenes such as door and window profiles, decorative profiles, panels, and furniture edge banding. The PVC profile foaming agent produced by our factory complies with the restrictions on heavy metals (lead, cadmium) and phthalates in EU and other regulations. At the same time, PVC foaming regulator for profile can significantly improve environmental performance and meet the needs of green buildings and sustainable packaging. Our factory will provide you with a full range of services with high-quality and low-cost products.

Foam structure optimization
PVC foaming regulator for profile promotes the formation of uniform and dense closed-cell structure, reduces the merging or collapse of foam cells, and improves the impact resistance, bending strength and dimensional stability of profiles. Density reduction range: conventional applications can reduce 10%~30% (matching the formula and process).
Improved processing performance
PVC foaming regulator for profile enhances PVC melt elasticity, improves melt strength at high shear rates, reduces melt fracture and surface defects during extrusion/injection molding, makes the material surface smoother, controls the foaming rate, optimizes melt fluidity, facilitates filling of complex molds, adapts to different mold structures and processing speed requirements, and reduces shrinkage and deformation after molding.
Energy saving and cost reduction
Reduce the amount of raw materials (reduce PVC resin consumption by 10%~20%), shorten the cooling time, increase production capacity, and at the same time reduce the foaming temperature, reduce energy consumption and equipment loss, and reduce the amount of foaming agent, thereby reducing production costs
Product type: rigid PVC foam profile
Application areas:
Building materials
Suitable for door and window profiles, window frames/sashes, door panels/door frames, wall panels, roof and exterior wall profiles, wardrobe/cabinet frames, skirtings and foam profiles, etc.

Extrusion process
Appropriately increase the screw compression ratio (such as 2.5:1~3:1), optimize the barrel temperature gradient, and ensure that the melt is fully plasticized.
Foaming section control
Adjust the foaming pressure and cooling rate according to the target density to avoid excessive expansion or shrinkage deformation.
Precautions
Compatibility test
Before the first use, it is necessary to verify the synergistic effect with other additives (such as plasticizers and fillers) in the existing formula.
Process debugging
When adjusting the amount of foaming agent and processing temperature, it is recommended to gradually expand production after a small test.
Safety protection
Wear dust masks and gloves during operation to avoid inhaling dust.
This product is a non-toxic, non-corrosive solid powder, and is not a dangerous item for transportation. It should be kept away from sunlight and rain, and is recommended to be stored in a cool and ventilated place indoors. The storage period is 1 year, and it can still be used after the performance test meets the standards. The packaging is generally 25 kg/bag, 500 kg/bag, and can also be customized according to customer requirements.
