Liquid PVC Stabilizers: Key Additives in the Production of PVC Transparent Calendered Sheet&Film

In the field of plastic processing, the production of transparent calendered films has always been a key area of concern for numerous enterprises. To manufacture high-quality transparent calendered films, PVC stabilizers are definitely indispensable key elements. Liquid PVC stabilizers are favored for their unique advantages. Compared with traditional solid stabilizers, they have better dispersibility. In the production process of transparent calendered films, they can be evenly incorporated into PVC materials, ensuring that each molecular chain is effectively stabilized and protected, which is crucial for maintaining the transparency of the films. Moreover, their liquid form makes the addition process more convenient and precise, avoiding local performance defects caused by uneven dispersion of stabilizers and laying the foundation for the production of high-quality transparent calendered films. Generally speaking, liquid PVC stabilizers suitable for transparent calendered films mainly include Methyl TinCalcium-Zinc and Carium-Zinc stabilizers.

Liquid Methyl Tin stabilizers possess excellent thermal stability and can effectively prevent the decomposition of PVC under high-temperature processing conditions, ensuring the transparency and color stability of the products. However, their costs are relatively high. In some application scenarios where cost is more sensitive, enterprises will seek alternative solutions.

PVC Barium Zinc stabilizers are a kind of thermal stabilizers with excellent performance. For transparent calendered films, they can provide good initial coloring properties, enabling the films to maintain a good appearance and color in the early stage of processing. They also have good long-term thermal stability performance and can ensure that the films are not prone to discoloration and aging during subsequent use. Meanwhile, the lubricity of barium-zinc stabilizers is moderate, which helps the material flow during the processing and makes the calendering process smoother and improves production efficiency.

PVC Calcium Zinc stabilizers, as representatives of environmentally friendly stabilizers, are gradually becoming the mainstream in the industry. Their biggest advantage lies in being environmentally friendly and non-toxic, which complies with the trend of increasingly strict environmental protection requirements for plastic products. In the production of transparent calendered films, calcium-zinc stabilizers can endow the films with good transparency and excellent weather resistance. Even if the films are exposed to outdoor environments for a long time, they can effectively resist aging and embrittlement problems caused by factors such as ultraviolet rays and oxygen, thus prolonging the service life of the films.
