SST-Porous®BD G00 series vents in grey color, made by over 95% PTFE material and some extend of black color, through special stretching process, thousands of “nodes” and “fibers” are formed.
As its proprietary e-PTFE microporous membranes allow air and gases to pass through freely, so moisture can diffuse before condensation problems arising.
SST-Porous® BD G00 series–Adhesive ePTFE protection vents in Gray color , research & developed by Spider(SST) independently. made by 100% PTFE material without backing material, combined with acrylic double-sided adhesive by precise processing to form a adhesive breathable protection vents.
SST-Porous®BD G00 series– adhesive protection vents in gray color, they could reliably keep out rain, sleet, snow, dust, dirt and debris, and continuously equalize internal pressure(compensate pressure). They could be mounted to the surface of the electronic component housing either automatically or manually.
By a special two-way stretchingg , the aggregation structure area of PTFE raw material was stretched to form ”fiber”, and the unstretched area formed “node”, thus the spidery porous PTFE material comes.
By means of powder metallurgy, PTFE powder will change to porous PTFE material in the form of flake or component through molding, sintering and skiving process.
By our precision die cutting process，BD G00 series could accept custom designed and sized venting products.
SST-Porous®adhesive &BD G00 series membrane, having color grey or black avalable, combined with acrylic adhesive then formed to air pemeable vents with excellent airflow.
BD G00 series characteristic (Before Application)：
Typical Airflow： > 400 ml/min/cm2（at ΔP = 70 mbar, RT）
SST-Porous® s-PTFE waterproof & breathable membrane, serial number named BD S00
SST-Porous® BD G00 serial–adhesive vents protection, due to the composition of “fiber” and “node” network structure, the vents not only with excellent permeability performance but outstanding water resistant.
※ BD G00 series (Before Application)：
①Water entry point (WEP)：>
50 kPa (Dynamic WEP 30 sec, RT)
②Ingress Protection (IP)：
(Protection against foreign particles, water, and touching 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 G00 serial characteristic (Before Application):
Oleophobic rate from 1 to 8 (according to AATCC 118)
SST-Porous®BD G00 series(no adhesive), 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 Goo series Adhesive venting in grey color, 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® white color BD G00 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 W00 series Adhesive vent in white color, the double-sided adhesive composition, package method, size, and shape could be customized.
※Venting 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 G00 series Adhesive protection vents in grey color, 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.
