Product Details

Melt polymer candle filter element of metal pleated filter elements fixed with candle holders to work as an candle-like filtration unit. Porous metal filters for high-temperature, high pressure polymer processing applications. Designed to remove the impurities ( such as titanium dioxide, gels and other solid residues ) of the polymer melt in chemical fiber, textile and plastics industries. Suitable for monomer, pre-polymer or polymer filter systems.Woven Metal Screen Pleated Candle Elements

Working Principle

The filtration system adopts one filter for filtering and one stand-by filter operation mode to achieve continuous, uninterrupted filtration process. First, the polymer melt enters into the filter from the bottom and flows from outside to inside. Impurities are trapped on the filter surface and clean melt flows from the filter inside to the clean melt pipeline at the top of the filter, and then flows out of the filter. When the differential pressure reaches the preset value, the filter filtration efficiency slows down, and the control system will convey the melt to another filter. At the same time, the filter for filtering is replaced and washed.
