Ultra-high molecular weight polyethylene as the material for plastic sintered porous filters.
Polyethylene powder that enables delicate pore size control due to the characteristics of true spherical microparticles and narrow particle size distribution, allowing for the formation of high-quality sintered filters with high filtration capability.
The need for high-performance gas and liquid filters with filtration functions has increased more than ever in the development of industrial machinery, medical devices, analytical instruments, and chemical products. Sintered filters are commonly made from metals, but there are many cases where resins are used due to chemical resistance issues. However, to create filters with a small average pore diameter, resins with small particle sizes are necessary. The reality is that such resins are not widely available in the market. This product is made from ultra-high molecular weight polyethylene with very small particles, allowing for the production of polyethylene porous sintered filters with uniform pore diameters due to its spherical shape and narrow particle size distribution. 【Basic Physical Properties of Fine Particles and Ultra-High Molecular Weight Polyethylene】 ■ Molecular Weight: 1.8 to 2 million ■ Particle Size: 10, 25, 30, 60 microns (general grade) ■ Melting Point: 136℃ 【Characteristics】 ■ Capable of manufacturing sintered filters with uniform pore sizes (average pore diameter also in the single-digit micron range) ■ By increasing the sintering temperature, tensile strength and elongation can be significantly improved, making it less prone to cracking ■ Excellent non-absorbency, high chemical resistance, and strong resistance to aging are achievable *For more details, please refer to the PDF document or feel free to contact us.
