In the field of plastic processing, foamed calendered products are widely used in multiple industries such as packaging, construction, and automobiles due to their unique properties, including light weight, heat insulation, and cushioning. In the production process of foamed calendered products, liquid barium-zinc, as a crucial additive, plays an indispensable role.
The liquid barium-zinc PVC stabilizer usually appears as a clear liquid light yellow. It possesses excellent thermal and light stability. In the initial stage of product processing, it can effectively inhibit color changes, enabling the products to maintain a good color tone. Moreover, it has excellent transparency, which can well maintain the color stability of the products. Compared with solid composite soaps, liquid barium-zinc has a stronger stabilizing effect. It does not generate dust, thus avoiding the risk of poisoning caused by dust. Additionally, liquid barium-zinc can completely dissolve in common plasticizers, has good dispersibility, and there is almost no problem of precipitation.
In the production of foamed calendered products, thermal stability is of vital importance. Liquid barium-zinc can effectively delay the thermal degradation of plastics during the processing, ensuring that the products can still maintain good performance under high-temperature environments. For example, in the production of PVC foamed calendered artificial leather, high temperatures can cause the PVC molecular chains to break, leading to a decline in the product’s performance. However, liquid barium-zinc can combine with the unstable structures in the PVC molecular chains to prevent further decomposition, thereby ensuring the quality of the artificial leather. In addition to thermal stability, liquid barium-zinc also has a positive impact on the foaming process. It can work in coordination with the blowing agent to promote the decomposition of the blowing agent at an appropriate temperature to generate gas, forming a uniform and fine cell structure. Taking PVC foamed shoe materials as an example, the addition of liquid barium-zinc makes the foaming process more stable, with a uniform distribution of cells, improving the cushioning performance and comfort of the shoe materials.
Compared with other types of stabilizers, liquid barium-zinc has obvious advantages. From an environmental protection perspective, it has no dust pollution, poses little harm to the health of operators, and does not produce harmful gases during the production process, which is in line with the current concept of green production. Moreover, liquid barium-zinc has good dissolution and dispersibility in plasticizers, and there will be no problems such as precipitation and separation out, reducing the equipment cleaning and maintenance costs during the production process.
