Sintered Porous Polyethylene (PE) Filter - Sintered Porous Filter - 亚博ag真人「信誉保障」filtration

Sintered Porous Polyethylene (PE) Filter


亚博ag真人「信誉保障」 sintered porous PE material is specially designed for specific filtration and venting applications.

Sintering is a special process for solid material.During the manufacturing process, it was made by heating and pressing the powder material under the temperature lower than its melting point.This special method endows the material with good chemical resistance and excellent corrosion resistance.

The sintered PE filter has a repeating linear molecular structure -CH2-CH2, inert structure, strong molecular bonds, and stable chemical resistance. Sintered Porous Filters (Polyethylene) is a common polymer filter material in the market. Characterized by good physical properties, light weight,good thermoplasticity, and wide pore size range from 1 to 70 um, which can be widely used in laboratory for solid-liquid filtration/separation, medical and pharmaceutical equipment, automatic industry devices, and water filtration systems.

Moreover, Self-Sealing porous plastic filter,a special kind of Sintered PE filters, can be used as a design option as self-sealing vent for filtering application,it is also widely used in medical & surgical applications.

Available Forms

- Sintered PE membrane
- Sintered PE plate / Polyethylene Porous Plates
- Various shapes of PE sintered porous plastics in customization

Material Feature

High-density polyethylene (HDPE)
HDPE can be used continuously at temperatures up to 180F (82C) and intermittently used at 240F (116C). It is generally used to make large pore size of PE sintered material.

Ultra High Molecular Weight Polyethylene (UHMWPE)
UHMWPE is a strong and light weight material,in addition to the characteristics of the high density polyethylene (HDPE) properties it also has the characteristics of resistance to acids, alkalis and multiple organic solvents. The temperature limit of this material is the same as HDPE. UHMWPE is generally used to make the small pore size material under 20μm.

Surface Feature

-  Hydrophilic
-  Hydrophobic
-  Hydrophobic and self-sealing when exposed to water

Product Feature

Advantages compared with microporous membranes
A. PE sintered materials can achieve similar performance as microporous membranes, However, the process requirements for users to assemble it to the device are very low. Generally, users can seal the filter and the device by mechanical pressing and mechanical interference fit, thus, no more need for complicated  and volatile welding method like ultrasonic welding, etc., which means less operational requirements on the user side. Moreover, using PE sintered material will not have the problem of static electricity during the punching process, which microporous membrane has.

Process comparisonof IV Catheter
Using microporous membrane : Punching membrane - static elimination - membrane fixing - welding - Infrared CCD weld inspection - gas inspection; 


Using sintered PE simplified process : filter assembly - gas inspection

B. Compared with other venting materials, PE sintered material has the unique advantage of self-sealing. Most of the venting materials (such as microporous membranes) have only the function of water repellent & venting, and two-way exhaust. But the self-sealing PE material will be self-sealed when contacting with water, can play functions as one way valve:  PE Filter.gif
