China Suppliers Factory - High-Quality Polymer Leaf Disc Filters for Plastic Film Industry Filtration
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 (FAQ)
What are Polymer Leaf Disc Filters used for?
Polymer Leaf Disc Filters are primarily used for polymer melt filtration in the production lines of BOPA, BOPET, and BOPP films. They remove polymer gel, coagulating agents, catalysts, and other solid impurities to ensure high-quality output in film, polyester, spinning, and chemical industries.
What is the maximum working temperature and pressure for these filters?
The polymer leaf disc filters can operate at a maximum working temperature of ≤300℃ and a maximum working pressure of ≤31.7MPa, making them suitable for demanding high-temperature and high-pressure industrial environments.
What filtration accuracy levels are available?
The filtration rate (βx≥75) is available in multiple levels: 5, 7, 10, 15, 20, 25, 30, 40, 60, 80, and 100 μm, allowing customers to select the most appropriate accuracy for their specific polymer melt filtration application.
Can the filter elements be cleaned and reused?
Yes. The polymer leaf disc filter elements can be repeatedly cleaned and reused through ultrasonic cleaning, which significantly reduces long-term operating costs and makes them an economical and sustainable filtration solution.
What are the differences between the Center Ring Welding Type and Center Ring Type?
The Center Ring Welding Type (soft hub) features a welded center ring design for flexible applications, while the Center Ring Type (hard hub) provides a rigid hub structure for more demanding or high-pressure conditions. Both types can be customized to meet specific polymer melt filtration requirements.
When should I choose filter discs over melt filter elements?
Filter discs are the preferred choice when dealing with recycled materials that have a very high impurity content, when continuous production requires a long replacement cycle, when melt pressure is extremely high, or when you are looking for a lower long-term operating cost despite a higher initial investment.
