Heat-Resistant Materials Selection

Select plastics with strong high-temperature tolerance like polyamide and polycarbonate
Avoid materials like low-density polyethylene that lose strength at high heat
Check the material's maximum continuous use temperature
Ensure the temperature rating exceeds the highest temperature of the target environment
Confirm the material retains chemical resistance at high temperatures in corrosive environments

Protective Performance Verification

Ensure the vent's protective functions hold up under heat
Check waterproof and dustproof ratings at elevated temperatures
Choose vents with heat-stable sealing components
Confirm breathable membranes don't melt or lose permeability at high temperatures
Test or review performance data over time in high-heat conditions

Structural Stability Evaluation

Opt for vents with robust structures that resist thermal stress
Avoid designs with weak points like thin walls or sharp edges
Choose vents with reinforced connections for equipment attachment
Select sturdy mounting structures as high heat can loosen fasteners
Ensure the vent's shape remains consistent at high temperatures

Application-Specific Matching

For environments with frequent temperature changes, select materials with low thermal expansion
In high-heat industrial settings, choose vents with additional heat dissipation features
Ensure the vent size provides sufficient airflow without sacrificing heat resistance
Check compliance with industry standards for high-temperature use
Pay special attention to regulated sectors like automotive or electronics
