SST-Porous®Adhesive/Weldable &BD01 series Protection Vents’s Features and Characteristics:

1 Breathability

SST-Porous®adhesive/weldable & white color BD01 series pemeable protection vents，formed by SST-Porous® pemeable membrane and none-woven polyester through hot-pressing process,  with excellent airflow.

2 Waterproof

SST-Porous®adhesive/weldable& BD01 series protection vents, as SST-Porous® air pemeable membrane’s special structure of “fiber” and “node” network, the protection vents not only with excellent airflow performance but outstanding water resistance.

3 Hydropobic & Oleophobic

SST-Porous® supply hydrophobic and Oleophobic protection vents to meet different application requirement. As it’s Oleophobic characteristic, the protection vent could maintaining airflow even after contact with high-viscous or low surface-tension liquids.

※  BD 01 serial characteristic (Before Application)：

 Oleophobic rate from 1 to 8  (according to AATCC 118)

4  Weldability

SST-Porous® weldable protection vents BD 01 series(no adhesive), The protection venting could be installed to the plastic housing by means of thermal melt or ultrasonic welding.

• A common type of plastic that could be welded

ABS，PBT，PP，HDPE，PA6，PC etc.

• Temperature of thermal welding

The temperature mainly depends on the melting point (Tm) of the plastic, generally 30~50℃ higher than selected plastic TM can be smoothly welded.

5  High adhesive strength

SST-Porous®BD BDo1 series Adhesive venting , the designed double-sided adhesive, in addition to its good adhesive with low surface PTFE  , but also take into account the viscosity of the surface with different materials.

※ Adhesion Properties of Adhesive

Adhesive strength according to FINAT FTM 1, RT Steel (after 24 h) ：      > 19 N/25 mm

6 Withstanding low and high temperature

Continuous Operating Temperature Range: -40 °C to +130 °C (when adhered)

Explanation：      

• the venting usage temperature mainly depends on the temperature of adhesive or the venting base material；
• if special temperature required, SST could supply adhesive venting with more wider range of temeprature.

7  none-PFOA

SST-Porous®s-PTFE adhesive/weldable & BD 01 serial,  the membrane used is different from e-PTFE material of PTEF, it’s obtained from suspension liquid, no need emulgator PFOA (PFOA suspected having carcinogenic effects), so SST-Porous® s-PTFE  adhesive/weldable & white color BD 01 serial  don’t have PFOA.

And，if specified SST-Porous® e-PTFE adhesive/weldable @ white color BD 01 series protective vents,  we could choose eco-friendly emulgator prepared by PTFE dispersion raw materials, thus, SST-Porous® waterproof & breathable vents do not contain PFOA.

8 可定制性

SST-Porous®背胶型/焊接型&白色BD01 系列透气膜可以根据客户的需求，选择不同类别的双面胶成分、堆叠方式、不同规格尺寸或者外观形状等。

※透气膜的外径（OD）和内径（ID）可选择     外径（OD）尺寸: 2~30 mm 内径（ID）尺寸: 1~28 mm   注意：   SST可根据客户来图或者设想最终确定不同形状或者规格的胶黏型透气膜制品

Handling/ Installation guide

SST-Porous®BD 01 series Adhesive protection 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.

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
