POROUS PLASTICS

porous_plastics.jpg
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

Advantages:

  • Uniform Air Distribution

  • Self Supporting

  • Easily Installed

  • Easily cleaned

  • High Corrosion Resistance

  • High resistance to shock and vibration

  • Working temperature between -94°F (-70°C) and 248°F (120°C)

  • FDA approved

Markets where POROUS PLASTICS are widely used include:

  • Aerospace and Defense

  • Chemical Process

  • Industrial Process 

  • Food and Pharmaceuticals

  • Nuclear and Energy
