cover Expanded Metal and Woven Screen Cloth with Elastomer Combinations.
This material comes as just the Metal or partnered with Silicone or Fluorosilicone to add environmental sealing.
We primarily suggest this material for use in applications where there are space concerns and/or where joint unevenness does not exceed .004 inches.
Order with or without PSA (Pressure Sensitive Adhesive) in sheet, strip or custom form as per your requirement.
