VAPOR MEMBRANES
Seal & Design specializes in cutting hydrophobic, oleophobic and hydrophilic ePTFE venting membrane materials. These venting systems equalize pressure in applications that require a continuous exchange of gases between internal and external environments, while preventing liquids and contaminants from entering your enclosure.
We manufacture our vents in a variety of standard shapes and sizes, but if you require a custom design, we can engineer the proper venting solution for any application. Our extensive material portfolio offers a specific product for every industry and application, including exterior light lenses, medical devices, electronic controls, pressure sensors and telecommunication devices.
Vapor Membranes have a variety of applications. A Seal & Design sales representative will be happy to help you find the best product for your application.

AUTOMOTIVE VENTING
Automotive Application Fact Sheet
Different aspects of automotive equipment are exposed to environmental changes such as temperature, water, dirt, debris, and even contact with automotive fluids.
Automotive vapor membranes provide reliable protection from debris, water, dust, and automotive fluids, while allowing for rapid equalization of pressure.
Reliable venting materials can reduce manufacturing costs and the complexity of component design by lessening the need heavier seals, gaskets, and housings.
Automotive vapor membranes can be found in automotive sensors, control units, motors, exterior lighting, powertrain, and power steering systems.
DIAGNOSTIC VENTING
Harsh environmental conditions can cause a decrease in performance and lifespan of sensitive electronics.
Telecommunications systems, solar energy systems, heavy duty equipment, and other outdoor applications contain electrical equipment that are exposed to environmental changes.
Proper ventilation provides protection from contaminants and liquids and promotes pressure equalization through air flow, effectively extending the life and performance of other seals.
HYDROPHOBIC BARRIERS FOR CAMERAS AND ELECTRONICS
Many cameras and portable electronics contain hydrophobic barriers to protect against liquids, dust, and pressure changes from everyday use.
Hydrophobic immersion vents protect sensitive electronics against moisture and allow for reliable protection of underwater cameras and devices.
MEDICAL VENTING
Medical personnel and patients rely heavily on medical equipment to perform safely and reliably. Microporous membranes are designed for high levels of gas permeability to allow for sufficient airflow and pressure equalization in medical devices.
Medical liquids can contain gases that may present a hazard to the patient or affect the operation of the device if not vented properly. IV lines, for example, use venting membranes to dissipate gas bubbles while retaining liquids under pressure.
OUTDOOR LIGHTING VENTING
Environmental changes can cause increased strain on the seals of sensitive outdoor equipment.
Outdoor lighting equipment is exposed to varying temperatures, moisture, and weather changes that can quickly decrease their performance, reliability, and lifespan.
Proper ventilation effectively blocks contaminants including dirt and dust, while allowing air flow to equal pressure, which will increase the service life of the equipment.
PACKAGE VENTING
Serious consequences can result from containers with active chemicals and formulations that are not properly ventilated.
These packages run the risk of bloating or collapsing, ruined labels, and leakage leading to costly cleanups and dissatisfied customers.
When it comes to agricultural products, and industrial and household chemicals and cleaners, leaks and ruptures could pose a severe risk to the users and the environment.
Proper ventilation allows air and gas molecules to pass, equalizing pressure, while preventing leakage of dangerous liquids.
SENSOR PROTECTION
Sensors are becoming smaller and more versatile allowing use in applications that were not previously possible.
Exposure to harsh environments including high-pressure, drastically changing temperatures, hazardous chemicals and gases, and contaminants can decrease the accuracy and functionality of a sensor.
Sensor Protection membranes provide an effective barrier against these conditions and can eliminate the effects of fluctuating temperatures and pressure differentials.
