Leaf Disc Filters for Polymer Film Filtration

Polymer films have a wide range of applications due to their properties and are commonly used in industries such as packaging, electronics, automotive, and biomedical as protective coatings, barrier layers, electronic device encapsulation, or as substrates for flexible displays.

As polymer film refers to a thin sheet or coating made from a polymer material. The primary purpose of leaf disc filters in polymer film filtration is to remove impurities, contaminants, and particles from the polymer melt or solution before the film formation process. This helps to ensure the production of high-quality and defect-free polymer films.

Product Description

FUTAI filtration solutions for the polyester film process often leverage advanced proprietary technologies to optimize product consistency, enhance quality, and minimize downtime.

During the process of film production, effective filtration is extremely important. All the waste particles, such as gels and physical materials, have to be removed. Because these waste particles can cause tears, create kind of abnormalities on the surface of film. Lack of quality filtration in the continuous polyester film manufacturing process can have several negative consequences, such as frequent filter changes, decreased productivity, lower product quality.

To avoid these issues, it is crucial to invest in high-quality filtration systems that can effectively remove particles and impurities from the manufacturing process. Regular maintenance and monitoring of the filtration system can also help optimize its efficiency and reduce the need for frequent filter changes.

Our leaf disc filters are well-developed products after we are delicate to developing and improving on it for many years by using advanced professional welding equipment and process. It has the characteristics of the resistance to high pressure & temperature, to chemical corrosion; and good permeability, large dirt-holding capacity, reliable performance and long lifetime with high strength, tenacity, excellent impact resistance, and can be repeatedly used after cleaning. It is mainly used for polymer filtration in the production line of BOPA, BOPET, and BOPP, in order to remove polymer gel, coagulating agent, catalyst, and other solid impurities. Discs filters are widely applied in the industry of film, polyester polymer, spinning, packaging materials, engineering plastics, oil, chemical and others.
