Custom China Suppliers Factory for Polymer Leaf Disc Filters in Plastic Film Filtration Industry Suppliers, Company

Leaf disc filters are essential components in the filtration of polymer films, primarily designed to effectively eliminate impurities, contaminants, and particles from polymer melts or solutions prior to the film formation process. This filtration step is crucial for ensuring the production of high-quality, defect-free polymer films, When compared to traditional melt filter elements, filter discs provide distinct advantages, including a larger effective filtration area, enhanced stability due to a robust mechanical structure, and ease of maintenance. Their design makes them particularly well-suited for high-demand environments characterized by elevated impurity levels, substantial output rates, and high pressure, As a leading factory in China, we are committed to supplying high-performance leaf disc filters that meet the diverse needs of our clients. Whether you are looking for reliable filtration solutions or sourcing suppliers in China, our products guarantee optimal performance and longevity in polymer film production processes

Product Description

Polymer Leaf Disc Filters
Our Polymer leaf disc filters are well-developed filtration 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. Polymer Discs filters are widely applied in the industry of film, polyester polymer, spinning, packaging materials, engineering plastics, oil, chemical and others.

How to Choose Between Filter Discs and Melt Filter Elements?
It depends on the specific production process requirements and economic benefit considerations.
When Filter Disc is Preferred
  • ✔ The Recycled Material has a very high impurity content.
  • ✔ Continuous production, pursuing an extremely long replacement cycle and the highest equipment stability.
  • ✔ The melt pressure is extremely high and the working conditions are harsh.
  • ✔ From a long-term economic perspective, willing to accept a higher initial investment in exchange for lower long-term operating costs.
When Melt Filter Elements are Preferred
  • ✔ The raw materials are relatively clean with low impurity content.
  • ✔ Extremely high requirements for filtration accuracy (some filter elements can provide even more extreme accuracy).
  • ✔ Due to limited space, a more compact filtration solution is needed.
  • ✔ Production batches are variable and require flexible adjustments, or the initial investment budget is limited.

Frequently Asked Questions (FAQ)
Q What materials are used in Polymer Leaf Disc Filters?
Polymer Leaf Disc Filters are made from stainless steel sintered fiber, multi-layer sintered stainless steel wire, and sintered metal powder. These materials ensure high strength, excellent corrosion resistance, and long service life.
Q What industries are Polymer Disc Filters suitable for?
Polymer Disc Filters are widely applied in the film industry, polyester polymer production, spinning, packaging materials, engineering plastics, oil, and chemical industries. They are especially used in BOPA, BOPET, and BOPP production lines.
Q What filtration accuracy levels are available for Polymer Leaf Disc Filters?
The available filtration rates (βx≥75) include: 5, 7, 10, 15, 20, 25, 30, 40, 60, 80, and 100 μm, allowing you to select the appropriate precision based on your specific application requirements.
Q Can Polymer Leaf Disc Filters be cleaned and reused?
Yes. The filter elements can be repeatedly cleaned using ultrasonic cleaning methods and reused after cleaning, which significantly reduces long-term operating costs and is more economical for continuous production environments.
Q What are the maximum working pressure and temperature for these filters?
Polymer Leaf Disc Filters support a maximum working pressure of ≤31.7MPa and a maximum working temperature of ≤300℃, with an allowable pressure differential of ≤10MPa, making them suitable for demanding high-pressure and high-temperature polymer melt filtration applications.
Q What types of Polymer Leaf Disc Filters are available?
Two main types are available: the Center Ring Welding Type (soft hub) and the Center Ring Type (hard hub). Both types can be customized to meet specific polymer melt filtration requirements based on your production conditions.
