Sinter plate filter is a kind of shape stability and strong resistance to impact and load ability of filtering material.  It is also called “plastic sinter plate”. The rigid filtering plate whose matrix is made of PE powder through special sinter process, and coated with PTFE (commonly known as “Plastic King”, the coating material of non stick pot). Due to pure surface filtration, it blocks the dust outside the filter material and is easily to be cleaned on line. It has a stronger filtration accuracy, which can be applied to various high or low temperature environments, and can be used repeatedly, effectively reducing the production cost.
