High-Quality High-Quality Polymer Leaf Disc Filters for Plastic Film Industry - China Suppliers & Factory Manufacturer, Factories

Leaf disc filters serve a crucial role in polymer film filtration by effectively removing impurities, contaminants, and particles from polymer melts or solutions prior to the film formation process. This filtration is essential for producing high-quality, defect-free polymer films, Compared to traditional melt filter elements, leaf disc filters offer several advantages: they feature a larger effective filtration area, enhanced stability due to a more robust mechanical structure, and ease of maintenance. These attributes make them particularly well-suited for high-impurity, high-output, and high-pressure operating conditions, As a leading factory and supplier in China, we provide top-of-the-line leaf disc filters that meet the stringent demands of the polymer industry, ensuring optimal performance and reliability for your filtration needs

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.
The situation where the filter disc is preferred:
  • The Recycled Material (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, they are willing to accept a higher initial investment in exchange for lower long-term operating costs.
Situations where melt filter elements are preferred:
  • The raw materials are relatively clean with low impurity content.
  • It has 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.
  • The production batches are variable and require flexible adjustments, or the initial investment budget is limited.

Frequently Asked Questions

Q What are the primary applications of Polymer Leaf Disc Filters?
They are mainly used for polymer filtration in BOPA, BOPET, and BOPP production lines to remove polymer gel, coagulating agents, catalysts, and other solid impurities. They are widely applied in film, polyester polymer, spinning, packaging, engineering plastics, oil, and chemical industries.
Q What materials are used to manufacture these filter discs?
The filter media materials include stainless steel sintered fiber, multi-layer sintered stainless steel wire, and sintered metal powder to ensure high durability and filtration performance.
Q Can the Polymer Leaf Disc Filters be cleaned and reused?
Yes, one of the key features of these filter elements is that they can be repeatedly used after being cleaned by ultrasound, making them highly cost-effective over their long lifetime.
Q Under what conditions is a filter disc preferred over a melt filter element?
A filter disc is preferred when the recycled material has a very high impurity content, during continuous production requiring long replacement cycles, under extremely high melt pressure, or when you want to achieve lower long-term operating costs despite a higher initial investment.
Q When should I choose a melt filter element instead of a filter disc?
Melt filter elements are preferred when raw materials are relatively clean with low impurity content, when extremely high filtration accuracy is required, when space is limited, or when production batches are variable and require flexible adjustments with a limited initial budget.
Q Can you customize these filters for specific applications?
Yes, high-quality polymer disc filters can be customized and provided to meet your specific requirements of polymer melt filtration applications.
