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.
✅ Filter Disc Preferred
- High impurity content in recycled materials.
- Continuous production requiring long replacement cycles.
- Extremely high melt pressure and harsh conditions.
- Preference for lower long-term operating costs over initial investment.
✅ Melt Filter Elements Preferred
- Raw materials are relatively clean (low impurities).
- Extremely high requirements for filtration accuracy.
- Limited space requiring compact solutions.
- Variable production batches or limited initial budget.

Frequently Asked Questions
What are the primary applications for Polymer Leaf Disc Filters?
They are mainly used in production lines for BOPA, BOPET, and BOPP to remove polymer gels, catalysts, and solid impurities. They also serve the film, spinning, packaging, and chemical industries.
Can these filter discs withstand high temperature and pressure?
Yes, they are designed for harsh conditions, supporting working temperatures up to 300℃ and working pressures up to 31.7MPa.
Are Polymer Leaf Disc Filters reusable?
Yes, these filters are highly durable and can be repeatedly used after professional cleaning, such as ultrasonic cleaning processes.
What materials are used to manufacture the filter media?
The media material typically includes stainless steel sintered fiber, multi-layer sintered stainless steel wire, or sintered metal powder.
Why choose a filter disc over a standard melt filter element?
Filter discs are preferred when handling high impurity recycled materials, requiring extremely long replacement cycles, or operating under extreme pressure where long-term cost efficiency is a priority.
