Navigation System, Infotainment System, Telematic Control Units, etc.

Compared to the harsh external environment, the vehicle interior appears relatively mild. However, with the rapid development of intelligent cabins, autonomous driving, and connected vehicles, the number and precision of in-vehicle electronic devices continue to increase. Voice interaction systems now incorporate more microphones and speakers. Any failure of these components can lead to serious consequences, making effective protection essential.

Different audio and electronic components have varying protection requirements. For example, the main control panel requires pressure-balancing vents, while speakers need acoustic vents that allow sound transmission. The rear cover often requires waterproof acoustic vents. Installing high-performance venting products is an economical and effective way to significantly improve the reliability of interior electronic equipment.

Long-term operation of in-vehicle electronics faces the following key risks:

• Dust accumulation and ingress into the housing, causing equipment failure.
• Temperature fluctuations creating internal pressure that damages seals and weakens overall protection.

Spider Waterproof and Breathable Solutions not only ensure excellent product performance but also provide outstanding long-term stability, giving customers peace of mind.

Gearbox, SCR, Urea Dosing Pump, Front-Wheel Drive Module, Rear-Wheel Drive Module, EPS, etc.

The powertrain system is responsible for generating and transmitting power to the wheels. It contains some of the most critical vehicle technologies and directly determines the vehicle’s mobility, economy, and environmental performance.

Most powertrain components are mounted on the vehicle chassis and are directly exposed to the external environment. During daily driving, rainy conditions, or wading, these components face rapid changes in water pressure, temperature, and air pressure.

Spider Venting Solutions — including Snap-fit Vent, Screw-in Vent, and Weldable Membrane — offer excellent pressure resistance. They enable chassis components to withstand strong water pressure impact during immersion while providing superior airflow to quickly balance internal and external pressure differences caused by environmental changes. This effectively prevents leakage and protects sensitive components.

New energy vehicles (pure electric, hybrid, plug-in hybrid, and 48V mild hybrid) have significantly more electronic components on the chassis than traditional vehicles. Ensuring the long-term stability and reliability of these high-value systems — such as battery packs, drive motors, motor controllers, and vehicle controllers — is a major challenge.

Drive Motor & Motor Controller High-power drive motors generate substantial heat, while internal gear movement causes frequent pressure changes. They are also exposed to oil vapor, dust, and liquids. Spider’s Snap-fit Vent provides high protection rating and large air permeability, effectively balancing pressure, dissipating heat, and preventing ingress of contaminants.

Power Battery Pack As the core and most valuable component of new energy vehicles, the battery pack is mounted on the chassis and heavily influenced by the environment. It requires high air permeability due to its large internal volume, along with strong chemical corrosion resistance. Spider’s ePTFE membrane solutions offer:

• Multiple product forms for greater design flexibility
• Large air permeability to improve efficiency and reduce overall cost
• Excellent consistency for superior product stability

• Moisture permeability and chemical/high-temperature resistance to prevent corrosion

Spider Venting Solutions provide reliable waterproof, dustproof, and breathable performance, helping new energy vehicle manufacturers ensure the safety and durability of critical power electronics and battery systems.

Position Sensor, Temperature and Humidity Sensor, Oxygen Sensor, etc.

Modern vehicles use over 100 types of sensors to monitor displacement, force, speed, temperature, flow, gas composition, and more. These sensors are installed throughout the vehicle — in the suspension system, interior, exterior, and engine compartment. Sensor failure can lead to serious consequences, making stable and reliable operation critical to vehicle safety and performance.

To ensure reliable sensor performance under harsh conditions, waterproof, dustproof, high-temperature resistant, and rapid pressure-equalizing capabilities are essential. High-performance waterproof venting products are therefore a key protective solution.

Different sensors have unique protection requirements:

• Temperature and Humidity Sensors need venting products that maintain sensitivity in high-humidity and high-temperature environments.
• Gas Sensors require careful selection of membrane materials, adhesive layers, and substrates to avoid affecting sensitivity.
• Flow Sensors demand minimal interference with target gas flux from the venting membrane.

Spider has extensive practical experience helping customers select the most suitable breathable solutions. For example, Spider’s high-temperature resistant venting membranes combined with high-temperature adhesives ensure long-term stable operation in demanding environments. With a wide range of membrane types available, Spider can adapt to diverse sensor application scenarios.

Millimeter Wave Radar, Ultrasonic Radar, On-board Camera, Lidar, Autonomous Driving Controller, etc.

Autonomous driving hardware is mainly divided into perception, decision-making & control, and execution systems. Perception equipment — including Lidar, vehicle cameras, millimeter wave radar, ultrasonic radar, and more — serves as the “eyes” of the vehicle, providing critical environmental data.

Safety is the top priority for both consumers and automakers in autonomous driving technology. While algorithms and big data improve decision-making accuracy, the quality and reliability of raw data from sensing equipment are fundamental. Any failure or inaccuracy in perception hardware can have catastrophic consequences.

Sensing equipment often operates in complex and harsh environments. High-performance venting products are essential to improve stability and reliability. For example:

• Millimeter Wave Radar is highly sensitive to environmental changes and must pass stringent tests (e.g., over 1000 thermal shock cycles or 1200 hours of high-temperature testing).
• On-board Cameras require venting products that provide anti-fogging, pressure equalization, and custom designs to fit compact housings.

Spider brings rich application experience in autonomous driving systems, helping ensure the long-term reliability of these critical sensing devices through advanced waterproof and breathable solutions.

Wiper Motor, Swing Window Motor, Cooling Motor, Starter Motor, etc.

Small motors are essential components that enable many vehicle functions, such as wipers, power windows, cooling systems, and engine starting.

These motors are often exposed to rain, dust, and harsh environmental conditions. Water ingress can cause circuit failure and motor shutdown, while dust entry may lead to abnormal noise and reduced performance.

Spider Venting Solutions effectively protect these motors with reliable waterproof and dustproof performance. They keep the interior dry and clean during wading, heavy rain, or car washing, ensuring continuous and stable operation.

Spider offers a variety of high-performance venting products:

• Weldable Vent — excellent consistency and high water-pressure resistance, ideal for demanding motor applications.
• Adhesive Vent — adapts to various surfaces and is easy to install.
• Snap-fit Vent — offers good fault tolerance and stable long-term performance.

Multiple installation methods (snap-fit, weldable, adhesive, etc.) are available to meet different customer design requirements.

The active ingredients in many industrial chemicals — such as hydrogen peroxide, sodium hypochlorite (bleach), peracetic acid, and organic peroxides — can decompose inside the container and release large amounts of gas. Without timely venting, this buildup can cause packaging to bulge or even burst, creating serious safety hazards.

Even for hot-filled chemicals that do not generate gas, temperature differences before and after filling create significant pressure changes. Without proper pressure balancing, containers may deform, damaging product appearance and sales performance.

Spider Solutions effectively address these issues with high-performance Vent Plugs and PE Foam Induction Liners.
