SST-Porous ® Black adhesive vents BD 04 series,  made by SST porous ® ePTFE membrane which compounded with polyester or nylon fabric, and then combined with acrylic adhesive. The BD 04 series adhesive vents are formed with different color choices to reduce the abrupt feeling of breathable membrane and plastic parts.

What is SST-Porous® adhesive & BD 04 series waterproof  breather vents membrane?

SST-Porous®adhesive &BD 04 series breathable vents, reseach and developed by SST independently. made of SST-Porous® PTFE membrane and base material of PET or Nylon fabric,formed through a special composite process.  SST-Porous® BD 04 series,  vents still maintains a high permeability and average pore diameter, but not easily stratified.  Color blue and Black for your choice. 

SST-Porous® BD 04 series, The breathable membrane and acrylic adhesive are precisely processed and combined to form a adhesive breathable vent product.

SST-Porous® adhesive &BD04 series, permeable membrane vents is waterproof, dustproof but breathable, equalize pressure (pressure compensation), be fixed to the surface of the electronic component housing either automatically or manually.   

 

SST-Porous®Adhesive &BD04 series breather vents processing

 

SST-Porous® PTFE breather membrane,  through precision die cutting process, die cut the adhesive membrane to different sizes according to the actual working conditions or customer specifications,  made into SST bulk production for delivery.

Handling and Installation guide

SST-Porous® adhesive & BD04 series breather vents, it is a high-tech products that need professional final-processing.

Please contact us when planning to enter your manufacturing process, not all final-processings are compatible with this product. We will be pleased to offer our expertise in this field to you.

  • Installation Surface

Recommended Surface roughness:Rz<10µm(max:Rz<16μm)。

Mounting surfaces should be dry and clean and free of oils, particles, release agent and other contaminants. the loose oxide layer on the surface will reduce the durability.

  • Recommeded cleaning

Grease free solvent, like heptane, isp[ropanol or alcohol.

In case of incompatibility, select another cleaning agent for the application surface.

  • Pressure sensitive adhesive operation guide

Press fit——suitable for semi-automatic installation

To achieve excellent press fit design and to obtain appropriate pressure,please follow the general recommendations as below:

  • Pressing head shall be made by soft rubber of uniform thickness and at least 0 mm thickness(Shore hardness A  20 — 40 )
  • The pressing head shall be vertical to the mounting surface and located in a position to apply pressure to the target/guard ring
  • Accoding to the size of adhesive area, apply uniform pressure 7 bar recommended to the adhesive ring to seal device or housing. The pressure on the surface of the pressing head should be appropriate to avoid pressing into the venting area
  • After pressing, the dwell time should exceed 5 seconds
  • Allow at least 24 hours dwell time before using or testing the vent
  • The above steps are very important to ensure the vent sealed on the housing firmly

Press fit——suitable for manual installation

  • Ensure the entire adhesive ring is attached to the surface of the device or housing
  • Apply light finger pressure to the adhesive ring at least two circles to assure the seal to the device or housing, be carefull not touch the central part of the vent
  • Allow at least 24 hours dwell time before using or testing the vent
  • The above steps are very important to ensure the vent sealed on the housing firmly
