SST-Porous ® BD T series vent caps / vent plug / vent cap made by SST porous® ePTFE membrane and thermoplastic elastomer welded together by ultrasonic or hot pressing process, after then assemblied with polypropylene shell cover.

The whole component has new functions and characteristics, reduces the cost, and can realize one click installation.

Product overview

SST-Porous® BD T series Vent Caps are developed independently, made by SST porous ® ePTFE membrane( with PP+PE support layer ) welded together with thermoplastic elastomer (EPDM, TPE and other materials) by ultrasonic or hot pressing and combined with PP shell cover.  Porous ePTFE material is protected by PP shell cover, which can prevent it from puncture, collision and other injuries, improving service life, safety, reliability and durability of the product. The whole component has new functions and characteristics of reducing the cost, and realizing one click installation.

 

Typical characteristics

※  With excellent water resistance, airflow, hydrophobic and oleophobic characteristics

※  Easy to install

Venting

SST-Porous® BD T series Vent Caps，according to the difference airflow,  vents  is identified by different color of black, gray or brown polypropylene (PP) outer cover.

Product general categories are described in the table as below ：

The PP outer cover is black-small air permeability The PP outer cover is of gray-medium air permeability The pp outer cover is brown- -with large air permeability
Typical Airflow > 500 ml/min/cm2 > 10000 ml/min/cm2 > 15000 ml/min/cm2

Note：  

※ The permeability test is the permeability size before use (before application)
※ Test the pressure difference ，at ΔP = 70 mbar, RT

 

 Waterproof

SST-Porous® BD T series Vent Caps, with SST-Porous® ePTFE membrane laminated with no woven polyester layer  welded on . Due to the network structure of ePTFE membrane composed of “fiber” and “node”, it not only has excellent ventilation effect, but also has excellent waterproof effect.

Back PP outer cover –

small airflow

 Brown PP outer cover —

high airflow 
Water entry point (WEP) > 500 kPa —
IP rate
 IP65/ IP66（Depending on the installation structure）、IPX7、IPX8、IP69K IP54

Note：

※ Water entry point (WEP) test is the test value before application .             unit：kPa
※ Test condition，Dynamic WEP 30 sec, RT
※ Protection against foreign particles, water, and touching according to ISO 20653:2013

 

Hydrophobic and Oleophobic

In order to meet different application’s requirements, SST porous ® ePTFE  membrane (with no woven  polyester support layer) can provide hydrophobic and oleophobic modification. When facing low surface tension liquid, the  Vent Caps can meet the function of water and oil drainage in the application where there is possibility of contacting oil stains.

※SST-Porous® BD T series Vent Caps characteristic(s)  (Before Application)：

Oleophobic rate： 8  (according to AATCC 118)

 

 High and low temperature resistance

SST-Porous® BD T series Vent Caps，

with Characteristics of high and low temperature：-40 °C to +120 °C (after installed)

Note：       

※The service temperature of the product mainly depends on the final service temperature of base material PP cover, thermoplastic elastomer or breathable film；
※ For specific temperature requirements, SST application engineers can provide other vent caps  with a wider temperature range.

Free of PFOA

The material used in SST-Porous® sPTFE is different from the PTFE raw material used in ePTFE. It is obtained from suspension and does not need emulsifier perfluorooctanoic acid (PFOA) (PFOA is suspected to have carcinogenic effect). Therefore, if SST porous in the component ® s-PTFE membrane (no woven with polyester support) adopts s-PTFE type membrane, SST-Porous® BD T series Vent Caps do not contain PFOA harmful substances.

For specially designated, SST porous ® e-PTFE membrane (no woven with polyester support) can select PTFE dispersed raw materials prepared by environmental friendly emulsifiers, so as to make SST-Porous® BD T series Vent Caps do not contain PFOA.

 

 Customized

SST-Porous ® BD T series vent caps can be customized in different inner hole installation aperture,  different types of thermoplastic elastomer, different PP outer cover color, different air permeability and different IP ratep.

Mainly depends on different ePTFE membrane type.
