cars. It includes headlights, fog lights, taillights, signal lights, indicator lights,steering wheel lights, etc.For headlights, fog often appears in rainy days or high humidity environments, so it is necessary to quicklydisperse the fog. Some headlights are directly connected to the atmosphere.The negative pressure causedby the shutdown will cause external water, making the fog scene more serious, and will cause damage tothe components in the lamp.In this case, EPTFE film material is used to solve the problem of light fog inautomobiles. While the fog quickly dissipates, it can provide good protection during the operation of theheadlights to prevent the invasion of external water and dust.Automobile headlamps equipped with waterproof and breathable membranes have good luminousperformance even under extremely harsh road conditions and long-term stable operation. For fog lights, taillights, signal lights, indicator lights, turn signals and other lamps, although the power of the light-emittingelement is not too large, the space is relatively small, so good air permeability is also required, and thewaterproof breathable film of the car lamp has high protective performanceA suitable waterproof and breathable membrane is designed for various car lights, which solves the problemof waterproof and breathable of various car lights, improves the reliability of the car lights, prolongs theservice life of the car lights, and shortens the design and assembly time. SDA Sunda waterproof permeablemembrane can also help automotive lights block pollution from gasoline, diesel, hydraulic oil and lubricants.

Shangda SDA breathable membrane is hydrophobic and oleophobic, and its microporous structure allows gas to pass freely, whichcan balance the pressure diference and prevent rainwater, dust, oil and particles from invading. The micropores of SDA breathablemembrane are 700 times larger than air molecules, ensuring reliable air permeability and pressure balance. Micropores are 20,000times smaller than water droplets, which can effectively block liquid, dirt and debris from entering. The SDA breathable film caneffectively extend the service life of electronic components. In the application of auto parts, outdoor electronic equipment and otherfields.
