Fireproof Rubber Door Seal provides excellent fire resistance and reliable sealing performance for doors, ensuring safety and durability in harsh environments.
Material:
This fireproof rubber door seal is made from high-quality, fire-resistant EPDM rubber blended with special flame retardant additives, ensuring excellent heat resistance and long-term durability.
Application:
Ideal for use in fire-rated doors, industrial facilities, commercial buildings, and residential properties where fire safety and airtight sealing are essential. It effectively blocks smoke, dust, and flames from passing through door gaps.
Working Conditions:
The seal performs reliably under a wide temperature range from -40°C to 120°C (-40°F to 248°F). It resists aging, ozone, and weathering, maintaining its sealing and fireproof properties even in harsh environmental conditions.

Lip Seals (Rotary Shaft Seals)
Application: Installed between rotating shafts and cavities for dynamic sealing, preventing lubricant leakage or ingress of dust/water.
Rubber Products: Lip seals (with or without metal frames).
Materials: NBR (general oil resistance), PU (high wear resistance), FKM (fuel/high-temperature resistance).
Working Conditions: Used in motors, gearboxes, pumps, etc., with shaft speed ≤5,000 rpm, pressure ≤1 MPa, temperature -30°C to 150°C.
Bellows Seals (Flexible Compensation Components)
Application: Act as elastic compensation mechanisms in mechanical seals to adjust for shaft axial movement or eccentricity, ensuring sealing surface contact.
Rubber Products: Rubber bellows (molded or hydraulically formed).
Materials: Silicone (low-temperature/weather resistance), EPDM (water/ozone resistance), FKM (chemical resistance).
Working Conditions: Suitable for cryogenic pumps (e.g., LNG pumps, -196°C), chemical agitators (acid/alkali resistance), with displacement compensation ±5 mm and pressure ≤2 MPa.
Gaskets & Bushings
Application: Static sealing for end covers and flange joints in mechanical seals, or as auxiliary wear-resistant bushings.
Rubber Products: Flat gaskets, corrugated gaskets, wear-resistant bushings.
Materials: NBR (general sealing), PTFE-coated rubber (strong chemical resistance), EPDM (water/steam resistance).
Special Application Rubber Seals
High-Pressure Conditions: FFKM seals for ultra-high pressure (>100 MPa) and strong corrosion (e.g., concentrated hydrochloric acid, liquid oxygen), used in oil drilling mechanical seals.
Food & Pharmaceutical Grade: Medical-grade silicone seals, non-toxic and steam-sterilizable (135°C), for mechanical seals in pharmaceutical reactors.
Aviation-Grade: Radiation-resistant silicone seals for aircraft engines, enduring high temperatures (260°C) and speeds (>10,000 rpm), compliant with MIL-S-8802.
