Product Description

Polymer Filtration System For Plastic Film Industry

Polymer melt filter system is the latest development in polymer melt filtration. The system can be adapted to production data outcomes in a very short time frame with minimal effort (e.g., convert filter cartridges to filter discs).

Depending on the production requirements, our polymer filter is designed as a single chamber filter. Poly melt filters can be installed horizontally or vertically with possible filtration areas of 1.4 m² to 100 m². Heating is variable and can be carried out electrically, with steam or with heat carrier oil.

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.
