Porous PTFE Film
- Color: White
- Maximum Temperature: 500° F
- Specifications Met: UL 746C, UL 94 V-0
Shield vents on electronic and automotive equipment, such as cell phone microphones, from water, dirt, and debris without blocking them entirely. This film has tiny holes to let air, gas, and vapors pass through. Because it’s made of PTFE, it wicks away water. It also won’t react with most chemicals, though it can break down from alkali metal and high-temperature fluorinated agents. IP rated, this film stands up to dust, weather, washdowns, and even brief submersion.

Porous PTFE Adhesive-Back Discs
- Color: White
- Maximum Temperature: 250° F
Stick these discs onto breather and other circular vents to guard against water and dirt without obstructing flow. Often used in the electronic and automotive industries, they have very small holes so air, gas, and vapor can still pass through. These discs are made of PTFE to wick water away. They also won’t break down from most chemicals, except alkali metal and high-temperature fluorinated agents.
IP rated except for their adhesive, all seal out dust and stand up to some submersion. IP65-rated discs also handle low-pressure washdowns, while IP66-rated discs withstand high-pressure washdowns.
