Q
What is a polymer melt filtration system and how does it work?
A polymer melt filtration system is designed to remove solid impurities — such as polymer gel, coagulating agents, and catalysts — from molten polymer before it enters the extrusion or film production process. The molten polymer passes through filter media (discs or cartridges) that trap contaminants while allowing clean melt to flow through, ensuring consistent product quality.
Q
What types of polymers are compatible with this filtration system?
The system is compatible with a wide range of polymers including PA, PBT, PE, LDPE, PC, PEEK, PET, BOPET, PP, BOPP, PMMA, EVA, carbon-fiber, fiber, resin, film, sheet, and recycled polymer materials — making it highly versatile for various industrial applications.
Q
Can the polymer filter be installed both horizontally and vertically?
Yes. The polymer melt filter is designed for flexible installation. It can be mounted either horizontally or vertically depending on your production line layout and space requirements, with filtration areas ranging from 1.4 m² to 100 m².
Q
What heating methods are available for the polymer filtration system?
The heating system is highly flexible. It can be configured for electrical heating, steam heating, or heat carrier oil heating — allowing the system to be adapted to different facility setups and energy sources with ease.
Q
How durable are the filter elements, and can they be cleaned and reused?
The filter elements are engineered for long service life with high strength, tenacity, and excellent impact resistance. They are resistant to high pressure, high temperature, and chemical corrosion. After use, the filter elements can be thoroughly cleaned and reused multiple times, reducing operating costs significantly.
Q
In which industries are polymer disc filters widely used?
Polymer disc filters are widely applied across multiple industries including plastic film production (BOPA, BOPET, BOPP), polyester polymer manufacturing, spinning, packaging materials, engineering plastics, oil refining, and chemical processing, among others.
