China Suppliers and Factory for Polymer Leaf Disc Filters in Plastic Film 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.
🟦
Filter Disc
Preferred When:
- 1The recycled material has a very high impurity content.
- 2Continuous production, pursuing an extremely long replacement cycle and the highest equipment stability.
- 3The melt pressure is extremely high and the working conditions are harsh.
- 4From a long-term economic perspective, willing to accept a higher initial investment in exchange for lower long-term operating costs.
🟩
Melt Filter
Preferred When:
- 1The raw materials are relatively clean with low impurity content.
- 2Extremely high requirements for filtration accuracy (some filter elements can provide even more extreme accuracy).
- 3Due to limited space, a more compact filtration solution is needed.
- 4Production batches are variable and require flexible adjustments, or the initial investment budget is limited.

Frequently Asked Questions
Q
What industries are polymer leaf disc filters suitable for?
Polymer leaf disc filters are widely used in the film, polyester polymer, spinning, packaging materials, engineering plastics, oil, and chemical industries. They are especially suited for polymer filtration in BOPA, BOPET, and BOPP production lines.
Q
What is the maximum working pressure and temperature for these disc filters?
The polymer leaf disc filters support a maximum working pressure of ≤31.7 MPa and a maximum working temperature of ≤300 ℃, making them suitable for demanding high-pressure and high-temperature production environments.
Q
Can the polymer disc filter elements be cleaned and reused?
Yes. The filter elements can be repeatedly cleaned and reused through ultrasonic cleaning processes. This significantly reduces long-term operating costs and makes them an economical choice for continuous production environments.
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. This wide range allows customers to select the most appropriate accuracy level based on their specific polymer melt filtration requirements.
Q
What is the difference between the center ring welding type and the center ring type?
The center ring welding type (soft hub) uses a welded construction that provides flexibility and is suitable for applications with moderate pressure variations. The center ring type (hard hub) features a rigid structure, offering greater strength and stability under extreme pressure and temperature conditions.
Q
What materials are used in the construction of polymer disc filters?
Polymer disc filters are constructed using high-performance media materials including stainless steel sintered fiber, multi-layer sintered stainless steel wire, and sintered metal powder. These materials ensure excellent corrosion resistance, high strength, and reliable filtration performance over long service life.
