POROUS PLASTICS
Porous Plastic, developed by Porvair Technology, Ltd., is a fluidizing or filtering membrane that is uniform, lightweight, resilient and durable.
ATLAS POROUS PLASTICS are permeable plastics formed by a closely controlled unique sintering process. The sturdy sheets produced may be fabricated to meet individual requirements. Based on linear, high-density polyethylene of the Ziegler- type, the material is free of detachable fibers, has a good appearance, and a surface easily cleaned by backflushing, tamping or vibration. A uniform texture and smooth surface make for an attractive finished product.
Utilized since 1959, a partial list of applications include:
-
Liquid, gas, and air filtration
-
Pneumatic conveying of powders
-
Aeration
-
Pneumatic silencing
-
Use in fluid transfer devices
