What Is The Ingredient Of The Raw Material For The Molding Of PVC Film
Aug 01, 2018

The formulation of the PVC film is made of PVC resin as the main raw material, and then, according to the requirements of the use of the products, the proportion of the main raw materials is designed according to the formula, and the mixture of plasticizer, stabilizer, filling material and other auxiliary materials is added. After high speed mixing, mixing and pre plasticizing, the film products are rolled by calender rolls.

The proportions of various raw materials in the formulation of the PVC film are different, and the properties of the products after forming the films are different. For example, the stability, mechanical strength, heat resistance, cold resistance and flame retardancy of the products will change with the change of the raw material in the formula and the proportion of the material. Similarly, the operating conditions of the products are adjusted with the change of the formula, and the production and manufacturing costs of the products also fluctuate accordingly.

From this, it can be seen that the design of formula used in product manufacturing requires high technical requirements, and it needs more experienced technicians in production practice to design. Attention should be paid to some basic general requirements in formulation design.
