An antistatic breathable polyester fabric with an ePTFE membrane coating on 1 side. The fabric has a Stainless-Steel matrix providing static dissipation of electrostatic energy.

Advantages

  • 100% polyester needlefelt
  • White
  • Stainless Steel matrix for antistatic properties
  • Good chemical resistance
  • Air permeable
  • For breather bags and flexible connectors
  • ATEX suitable

Applications

Filter bags, breather bags, flexible sleeves, and flexible connections where there is a need for air permeable fabrics. For machine setups where pressure fluctuations need to be vented continuously.

Weighing Applications

PNV 7506 AS FG is suitable for Low volume batch sizes and high accuracy weighing and dosing applications due to the flexibility of the fabric.

Chemical Resistance

  • Resistance against acid – Good
  • Resistance against solvents – Good/average

ATEX & Explosion Safety

PNV 7506 AS FG has been tested for its electrostatic chargeability, the sample has been tested according to DIN 54345.

Test according to DIN 54345-1
Surface resistance ROT (geometric median of the values of five measurements each):

  • Side 1 (marked side):           RoT = 6.7*102 Ω
  • Side 2 (back side):                RoT = 2.0*103 Ω

Volume Resistance RDT (geometric median of the values of five measurements each:

  • RDT = 7.8*102 Ω

Test according to DIN 54345-5

Strip resistance Rst in warp direction (arithmetic median of five samples).

  • Rst30 = 1.6*103 Ω

Strip resistance Rst in fill direction (arithmetic median of five samples).

  • Rst30 = 2.7*103 Ω

Test was carried out with a test voltage of 1 V. Deviating from the provisions made in DIN 54 345, the test was conducted after at least 24 hours of storage at a temperature of 22 °C and a relative humidity of 34%.

The maximum permissible resistance value is: 108 Ω. This Value was under-run in all measurements. In an electrostatic sense, there is no objection to using the earthed filter material in hazardous places.
