Foaming regulator plays an important role in the production of PVC products, significantly improving the performance of PVC products by affecting the strength, flowability, plasticizing effect, and cell structure of PVC melt. The following are the specific effects of foaming regulators on the properties of PVC products:
Improve melt strength and flowability
Foaming regulator can improve the strength and flowability of PVC melt, which is one of its core functions. By increasing the cohesion and homogeneity of PVC melt, foam modifiers can make PVC products denser while ensuring good flowability of the melt, which is crucial for obtaining products with good appearance.
Prevent bubble merging
In the production process of PVC foam products, foam regulators can prevent the merging of bubbles, thereby obtaining uniformly foamed products. This is because the foaming regulator increases the melt strength of PVC foam material, so that during the process of bubble core expansion into bubbles, the melt is sufficient to cover the bubbles, making it difficult for gas to overflow and merge into large bubbles, thereby improving the product quality of foam sheets.
Improve surface glossiness
Some foaming regulators, such as Qihong K530, can improve the surface glossiness of products in addition to the above-mentioned effects. This characteristic is particularly important for PVC products that require high surface quality, such as PVC profiles, pipes, sheets, etc.
Adapt to different processing conditions
The selection of foaming regulators also needs to consider processing equipment and conditions. For example, different performance foaming regulators are suitable for different screw types and plasticizing abilities, as well as different PVC foaming density requirements. This indicates that foaming regulators can adapt to different processing conditions, thereby meeting the different needs of users.
economic benefits
By using foaming regulators, production costs can be reduced without sacrificing product quality. For example, adding fillers can improve the dimensional stability, impact strength, and rigidity of plastic profiles, while reducing costs.
In summary, foaming regulators have significantly improved the performance of PVC products through various means, including increasing melt strength and flowability, preventing bubble coalescence, improving surface glossiness, adapting to different processing conditions, and bringing economic benefits. These improvements not only improve the quality of PVC products, but also expand their application scope, meeting diverse market demands.
