What is the raw material formula for forming PVC film?
????? The raw material formula for the calendering of PVC film is based on polyvinyl chloride resin, and then, according to the performance requirements of the product use, the main raw materials are added with plasticizers, stabilizers, fillers and other ingredients according to the formula design ratio Auxiliary raw materials are mixed and composed. After high-speed mixing, kneading and pre-plasticization, the film products are rolled by the roller of the calender.
???? The composition ratio of various raw materials in the formula for making PVC film is different, and the performance of the product after forming the film is also different. Such as the stability of product performance, mechanical strength, heat resistance, cold resistance and flame retardance, etc., will change with the change of the raw materials in the formula and the proportion of the materials used. Similarly, the operating process conditions during the production of products are adjusted with the changes in their formulations, and the production and manufacturing costs of the products must also fluctuate accordingly.
???? It can be seen from this that the technical requirements for the design of formulations for product manufacturing are relatively high, and it requires technical personnel with rich experience in production to design. Attention should be paid to some basic general requirements when formulating.
