SST-Porous®adhesive BD 03 series, application for consumer electronics to solve the problem of pressuer difference between the external environment and the inside of the device when electronics experiences temperature or altitude changes. This difference in pressure will impair the effectiveness of gaskets and seals in the electronics and ultimately result reduction in liquid penetration resistance. Our SST-Porous® BD 03 series protecion venting could meet the requirement of 3ATM and 5ATM water resistance.
SST-Porous®adhesive &BD03 series-3ATM & 5ATM high water pressure resistant breathable vents, reseach and developed by SST independently, made of SST-Porous® high water pressure resistant PTFE membrane and supported material of modified polyester non-woven fabric, combined with acrylic double-sided adhesive by precise hot processing to form a adhesive high water pressure resistant breathable membrane .
SST-Porous®adhesive &BD03 series–3ATM &5ATM high water pressure resistant breathable vents, with characteristic of high air permeability, dustproof, pressure equalization( pressure compensation–the pressure difference can weaken the gaskets and seals in the device, causing bias in the acoustic components and affecting acoustic performance ), the vents can be fixed to the surface of the electronic component housing either automatically or manually, keep the air permeability of the device and resist water pressure up to 30 m (3ATM) and 50 m (5ATM)( Vent ID 1.6mm/OD 4.2mm, 10minutes)
SST-Porous® BD 03 series 3ATM&5ATM high water pressure resistant membrane, through precision die cutting process, die cut membrane and back gum to different sizes according to the actual working conditions or customer specifications.
SST-Porous®adhesive &BD 03 series 3ATM &5 ATM high water pressure resistance membrane, made of SST-Porous® high water pressure resistant PTFE membrane and supported material of modified polyester non-woven fabric, combined with acrylic double-sided adhesive by precise hot processing to form a adhesive high water pressure resistant breathable membrane. The vent ensures high water pressure resistance and keep good air permeability to effectively ensure the pressure equalization(pressure compensation)– This difference in pressure will impair the effectiveness of gaskets and seals in the electronics and ultimately result reduction in liquid penetration resistance.
Typical Airflow： > 100 ml/min/cm2（at ΔP = 70 mbar, RT）
Typical Airflow： > 300 ml/min/cm2（at ΔP = 70 mbar, RT）
SST-Porous® BD 03 serial–3ATM &5 ATM high water pressure resistance membrane, as the composition of “fiber” and “node” network structure, the vents not only with excellent permeability performance but outstanding water resistant.
SST-Porous® BD 03 serial–3ATM &5 ATM high water pressure resistance membrane (Before Application)：
Water entry point (WEP)
> 300 kPa
> 500 kPa
|Ingress Protection(IP rate)||IPX7、IPX8||
※ WEP test condition，Dynamic WEP 30 sec, RT
※ Protection against particles, water, and others according to ISO 20653:2013
SST-Porous® could supply hydrophobic and Oleophobic 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 03 serial characteristic (Before Application):
Oleophobic rate from 1 to 8 (according to AATCC 118)
SST-Porous®BD 03 series, The breathable venting could be mounted on the plastic housing by means of thermal melt or ultrasonic welding.
Common type of plastic that could be welded
The temperature mainly depends on the melting point (Tm) of the plastic, generally 30~50℃ higher than selected plastic TM can be smoothly welded.
SST-Porous®BD o3 series high water pressure resistant breather membrane, the designed double-sided adhesive, in addition to its good adhesive with low surface enery of 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
Continuous Operating Temperature Range: -40 °C to +130 °C (when adhered)
SST-Porous®BD S00 serial, adhesive venting in white color, the membrane used is e-PTFE material different from PTFE material, it’s obtained from suspension liquid, no need emulgator PFOA (PFOA suspected having carcinogenic effects), so BD S00 serials dont have PFOA.
And，if specified SST-Porous® BD 03 series Adhesive vent , we could choose eco-friendly emulgator prepared by PTFE dispersion raw materials, thus, SST-Porous® waterproof and breathable membranes do not contain PFOA.
SST-Porous®BD 03 series Adhesive vent, the double-sided adhesive composition, package method, size, and shape could be customized.
※Vent size OD&ID option:
OD size: 2~30 mm
ID size: 1~28 mm
SST could produce the adhesive venting according to customer drawing or sample.

SST-Porous®BD 03 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.
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.
Grease free solvent, like heptane, isp[ropanol or alcohol.
In case of incompatibility, select another cleaning agent for the application surface.
