Custom Polymer Leaf Disc Filters for Plastic Film Industry - High-Quality Solutions from China Suppliers and Factory Factories, Exporter

Leaf disc filters play a crucial role in polymer film filtration by effectively removing impurities, contaminants, and particles from the polymer melt or solution prior to the film formation process. This ensures the production of high-quality, defect-free polymer films. As a leading factory in China, we provide advanced filter solutions tailored to meet your needs, Compared to traditional melt filter elements, our filter discs offer significant advantages, including a larger effective filtration area and enhanced stability due to their robust mechanical structure. These factors make filter discs particularly well-suited for high impurity environments, as well as applications requiring high output and high pressure. As trusted suppliers in the industry, we prioritize convenience in maintenance, ensuring optimal performance in your production line

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.
The production batches are variable and require flexible adjustments, or the initial investment budget is limited.

❓ Frequently Asked Questions (FAQ)

Q 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 effectively remove polymer gel, coagulating agents, catalysts, and other solid impurities, ensuring high-quality output in industries such as film, polyester polymer, spinning, packaging materials, engineering plastics, oil, and chemicals.

Q What filtration accuracy levels are available for Polymer Disc Filters?

Our Polymer Disc Filters are available in a wide range of filtration ratings (βx≥75), including 5, 7, 10, 15, 20, 25, 30, 40, 60, 80, and 100 μm, allowing customers to select the appropriate precision for their specific application requirements.

Q What is the maximum working temperature and pressure for these filters?

The Polymer Leaf Disc Filters can withstand a maximum working temperature of 300℃ and a maximum working pressure of 31.7MPa, with an allowable pressure differential of up to 10MPa. These specifications make them suitable for demanding industrial environments.

Q Can Polymer Disc Filters be cleaned and reused?

Yes. One of the key advantages of Polymer Disc Filters is that they can be repeatedly cleaned using ultrasonic cleaning methods and reused multiple times. This significantly reduces long-term operating costs and makes them a cost-effective choice for continuous production environments.

Q What types of Polymer Leaf Disc Filters are available?

We offer two main types: the Center Ring Welding Type (soft hub) and the Center Ring Type (hard hub). The media materials include stainless steel sintered fiber, multi-layer sintered stainless steel wire, and sintered metal powder. Custom configurations are also available to meet specific application needs.

Q How do I decide between a filter disc and a melt filter element?

The choice depends on your production process and budget. Filter discs are recommended when dealing with high-impurity recycled materials, continuous high-pressure production, or when long-term cost savings are prioritized. Melt filter elements are better suited for cleaner raw materials, compact installations, flexible batch production, or when a lower initial investment is required.
