U/E/D/P-Type Silicone Sealing Strips: Functions

I. Core Universal Functions

1. Water and Dust Sealing

• Door/window gap scenarios: D-type and P-type sealing strips are attached to door frames/leaves to prevent rainwater from seeping in and dust from entering the room.
• Automotive scenarios: U-type sealing strips are used in window glass runners and door frames to stop rainwater from penetrating the car cabin, protecting the interior trim and electronic components; E-type sealing strips are suitable for engine compartment covers and trunk lids to isolate dust, mud and water.

2. Buffering, Collision Prevention and Shock Absorption

• Automotive collision prevention: U-type and D-type sealing strips installed on the edges of car doors and trunks buffer impact force during door opening and closing, avoiding scratches caused by direct contact between metal components, and reducing door-slamming noise at the same time.
• Mechanical equipment scenarios: E-type and P-type sealing strips are applied to gaps in equipment cabinet doors and operation panels, reducing vibration transmission during equipment operation and lowering noise leakage.

3. Sound Insulation, Heat Insulation and Thermal Insulation

• Door/window gaps: After sealing strips fill the gaps, they reduce air circulation between indoor and outdoor spaces, improve the thermal insulation effect of air conditioners/heating systems, and weaken the transmission of external noise into the room.
• Car cabin: Sealing strips on doors and windows reduce wind and road noise during driving, enhance the quietness inside the car, and decrease heat exchange between the inside and outside of the cabin.

4. High Temperature Resistance and Aging Protection

• Automotive engine compartments: U-type and E-type sealing strips are used for wrapping and protecting pipelines and wire harnesses, withstanding high-temperature baking from the engine and preventing aging and cracking.
• Kitchen and bathroom door gaps: D-type sealing strips can withstand the high-temperature and high-humidity environment of kitchens and bathrooms, without hardening or deforming after long-term use.
