High-Quality Candle Filter Cartridge and Elements for Polymer Processing - China Suppliers and Factory Exporter, Companies
Candle Filter Elements are essential filtration units designed for high-temperature and high-pressure polymer processing applications. These robust metal pleated filter elements, manufactured by reliable suppliers in China, are equipped with candle holders for effective operation. They are engineered to efficiently remove impurities such as titanium dioxide, gels, and other solid residues from polymer melts, catering to the needs of the chemical fiber, textile, and plastics industries, Our candle filters are suitable for various filtration systems, including monomers, pre-polymers, and polymers. Typically tubular, these elements are constructed from durable stainless steel mesh or stainless steel sintered mesh, featuring a cap at one end and a threaded connector at the other, ensuring a secure connection to the core end. Additionally, some models include an outer surface made of perforated metal sheets, expanded metal, sintered metal, or porous ceramic to enhance the support for the filter media, When searching for reliable filtering solutions, consider our factory in China, known for producing high-quality Candle Filter Elements tailored for your specific processing needs
The melt filter element is installed in the extrusion line, where the polymer melt is forced through the filter to remove impurities. The candle filter element is placed inside the filter housing (housing). It is a compact device that can typically hold 1-20 candles, depending on the size of the filter. The filter element is arranged vertically in the pressure vessel to filter liquids with low solid content. The candle filter allows high productivity, easy bottom sediment discharge.
The main filter layer of Pleated Filter mainly uses two materials: stainless steel wire mesh and stainless steel Sintered fiber. Stainless steel wire mesh is woven from stainless steel wire. Its pleated filter has the characteristics of smooth pores, easy cleaning, high temperature resistance, corrosion resistance, no wire mesh falling off, and long filtration cycle. Stainless steel sintered fiber is a porous deep filter material made of stainless steel fibers sintered at high temperature. Its pleated filter has the characteristics of high porosity, good air permeability, strong dirt holding capacity, and strong regeneration ability.
