Single Layer And Point Welded Filter Disc
The Continuous Polymer Filter also offers single-layer and spot-welded mesh discs. Reply on our extensive experience and knowledge, we assist you in selecting the appropriate filtering media and structure for your application. Specifically designed for the smooth flow of polymers, ensuring polymer is squeezed out of the system smoothly and efficiently.
The melt polymer system with high pressure and high flow can also enhance the overall structural stability of the melt polymer filter through the spot welding component manufacturing process. These polymer film filters are designed for easy cleaning, simplifying the maintenance process and saving you time and money.
Polymer Leaf Disc
Polymer leaf disc is manufactured by sintering and laminating multiple layers of metal media. At its center is a hard hub structural bore, designed for critical hot melt polymer filtration applications. Polymer film filter achieves greater gel control by providing a smoother flow and retains more gel on the polymer melt filter leaf disc.
By combining different filter media configurations, Saifilter's polymer leaf disc can ensure lower pressure drop while achieving a longer online life. Its unique construction allows it to be cleaned multiple times, reducing the life cycle costs of polymer filtration systems.

Polymer Candle Filter
The polymer candle filter is suitable for the industrial polymer melt industry and is available in cylindrical and pleated designs, allowing for custom shell designs. There are two types of filter materials: sintered metal fiber and woven mesh. It is the first choice of melt polymer filter manufacturers.
Polymer candle filters are available in specifications from 3 to 100 microns, and they are typically equipped with an external shield of perforation plates designed to protect the medium and promote counterflow for effective cleaning.
Reduce the internal volume of all polymer filter elements to prevent stagnant flow areas within the candle design. A shunt built into the container ensures a uniform distribution of the polymer as it enters the housing.
Our high-strength, highly permeable stainless steel fiber media have a low initial pressure drop and a long operating life. This makes it the first choice for applications in industrial polymer melt filters.

Metal Powder Filter Packs
Metal powder filter packs are composed of stainless steel alloy powder particles with specific crushing shapes. The metal sand in the long-fiber and short-fiber spinning components consists of two or three layers of different particle sizes and quantities. To determine the best combination of powder mesh numbers, it is necessary to consider the type of polymer, viscosity, purity, polymerization efficiency, melt temperature, and extrusion speed in the spinning process.
In high temperature and high-pressure environments, the good strength of iron ensures that the particles are not easily broken and minimizes the possibility of blockage of the spinneret holes. At the same time, adding alloying elements such as chromium, nickel, silicon, and manganese enhances the strength of the stainless steel particle size, maintains high porosity throughout the filtration process, and effectively slows down the growth of pressure differential.
Our metal powder filter packs sand have irregular shapes and porosity of up to 70-80%, achieving an extremely high surface area. It is very effective in shearing polymer microgels and in intercepting foreign bodies or impurities in polymer melts. This ensures the highest purity and quality of the polymer emitted from the spinning components.
When polymers are sheared through the powder filter media, heat is generated and accumulates locally. However, the excellent thermal conductivity of the metal sand ensures a high degree of uniformity in the temperature inside the spinning components.
Precise control of polymer temperature is crucial to prevent capillary breakage and uneven fiber dyeing. Metal powder filter packs sand exhibit strong resistance to chemical and temperature environments, offering an economical and efficient solution for filtering hot polymers.

A polymer filter is a filtration device made using polymer materials, designed to remove solid particles, impurities, or contaminants from liquids or gases. They are commonly used in industries such as manufacturing, healthcare, and environmental protection.
Polymer filters offer advantages such as lightweight construction, corrosion resistance, cost-effectiveness, and versatility. These features make them suitable for various applications, particularly those requiring customized designs.
Polymer filters can be used in water treatment, food and beverage production, pharmaceutical manufacturing, chemical industries, and more. They can filter out particles of different sizes and types, ranging from tiny bacteria to larger impurities.
Maintenance of polymer filters typically involves regular cleaning and replacement of filter media. Cleaning can be done through methods like flushing or chemical cleaning, depending on the filter's operating environment and the nature of filtered substances.
The working principle of polymer filters is similar to traditional filters. They block solid particles by utilizing pores or porous polymer materials, allowing liquids or gases to pass through in a cleaner state. Filter material and pore sizes can be adjusted to achieve varying levels of filtration efficiency based on application requirements.
