In the production process of PVC foam products, foam control agents, also known as PVC foam controller or foam modifiers, are indispensable additives. They play a crucial role in controlling the cell structure, density, and overall quality of the foam, ensuring consistency in the foaming process and that the final product meets the required specifications. As a company specializing in the production of PVC foaming agents, calcium-zinc stabilizers, PVC impact modifiers, lubricants, and other chemical raw materials, Hairuite is deeply aware of the importance of PVC foam controllers and their applications in production.
PVC foam controllers are plastic processing aids and belong to chemical substances. There are many precautions for their storage and use. First, these regulators change their properties when exposed to heat, so they need to be kept away from flames, hot pipes, heaters, or other heat sources. Moreover, adding PVC foam controllers might generate dust, which can harm the body if it comes into contact with the eyes or skin. Therefore, it is advisable to minimize dust dispersion during processing, and if it accidentally gets into the eyes or touches the skin, it should be rinsed timely with water.
The main purpose of adding PVC foam controllers is to increase the strength of the melt, prevent the merging of bubbles, and make the foaming more uniform, thereby producing better PVC foam products. PVC foam control agents can promote the plasticization of PVC, ensuring good flow properties. This characteristic is crucial for producing high-quality PVC foam products.
When selecting PVC foam control agents, attention should be paid to the different degrees of PVC polymerization, such as PVC-700, PVC-800, and PVC-1000, which require different foam controllers. There are many types of plastic processing aids, and choosing the appropriate foam controllers based on the specific processing production needs is essential. At the same time, the amount and timing of using these agents should be selected based on the specific circumstances to achieve the best foaming effect.
Effect on Plasticization
PVC foam controllers can significantly promote the plasticization process of PVC resin, making PVC plasticization more uniform. This characteristic helps improve the surface gloss and quality of the products. In the production of PVC foam products, the quality of plasticization directly affects the final product's quality and performance. Therefore, choosing the right PVC foam controllers is crucial to improving the product's plasticization effect.
Enhancing the Cohesion and Homogeneity of PVC Melt
PVC foam controllers can significantly increase the pressure and torque of the PVC melt, thereby effectively increasing the cohesion and homogeneity of the PVC melt. This characteristic makes the resulting PVC products denser and improves their physical properties and mechanical strength. For instance, using a specific foam controller (such as JINHASS) can result in significant changes in PVC melt pressure and torque. These changes directly reflect the enhancement of the PVC melt's cohesion and homogeneity.
Enhancing the Strength of PVC Melt
PVC foam controllers can also significantly increase the strength of the PVC melt. Higher melt strength aids in maintaining bubble shape and preventing hole breakage. This characteristic is critical for producing foam products with uniform bubble structures, low density, and good surface quality. Using suitable foam controllers can significantly enhance the strength of the PVC melt, resulting in higher quality foam products.
In short, the physical properties of PVC foam controllers are crucial for producing high-quality PVC foam products. Choosing the right foam control agents can improve the plasticization effect, enhance the cohesion and homogeneity of the PVC melt, and increase the strength of the PVC melt. In the production process of PVC foam products, the selection and use of foam control agents have a decisive impact on the final quality and performance of the products. Therefore, selecting a professional and reliable supplier is essential.
