SST-Porous®BD W00 series vents in white color, made by 100% SST-Porous® membrane, through special stretching process, thousands of “nodes” and “fibers” are formed. For the white color requirementm BD W00 is your best choice.
SST-Porous® BD W00 series–ePTFE Adhesive vents in white color , research & developed by Spider(SST) independently. Material of 100% ePTFE membrane without backing material, combined with acrylic double-sided adhesive through precise processing to form adhesive air pemeable vent.
SST-Porous®BD W00 series–Adhesive Air Pemeable Vents, they could reliably keep out rain, sleet, snow, dust, dirt and debris, and continuously equalize pressure imbalances, to protect housing integrity and longer serive life, increasing reliability, and preventing deformations that could cause component failure. They could be mounted to the surface of the electronic component housing either automatically or manually.
By a special two-way stretching process, 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.
SST-Porous® s-PTFE, by means of powder metallurgy, through molding, sintering and skiving process, PTFE powder will change to porous PTFE material in the form of flake or component.
Through precision die cutting process，air pemeable membrane could be cutted into different size, so we could accept custom designed and sized protection vents.
SST-Porous®adhesive & BD W00 series protective vents, the color is the material PTFE color itself，PTFE membrane is combined with acrylic adhesive, then form to high airflow adhesive protection vents.
BD W00 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 W00 serial–adhesive protective vents , due to the composition of “fiber” and “node” network structure, the vents not only with excellent air permeability performance but outstanding water resistant.
① BD W00 serial characteristic (Before Application)
Water entry point (WEP)： > 50kPa (Dynamic WEP 30 sec, RT)
② IP rate
IP54、IP65/ IP66（subject to the mounting struction ）、IPX7、IPX8、IP69K(Protection against 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 W00 serial characteristic (Before Application):
Oleophobic rate from 1 to 8 (according to AATCC 118)
SST-Porous®BD W00 series(no adhesive), The breathable venting could be mounted to the plastic housing by means of thermal melt or ultrasonic welding.
Common type of plastic that could be welded
The welding 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 Woo series Adhesive Protective vents, 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
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 W00 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 Beathable Protection vent, customer could choose different double-sided adhesive composition, package method, size, and shape.
※vents size OD&ID option:
OD size: 2~30 mm
ID size : 1~28 mm
SST could produce the adhesive vents according to customer drawing or sample.

SST-Porous®BD W00 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.
