I. Outstanding Weather Resistance and Aging Resistance

• Strong UV and Ozone Resistance: The molecular structure of EPDM rubber is stable, effectively resisting UV rays, ozone, and climatic aging. It is not prone to cracking, hardening, or embrittlement in long-term outdoor environments, with a service life of over 20 years.

• Wide Temperature Range: It maintains good elasticity and sealing performance between -50°C and +150°C, remaining stable in extreme high or low temperatures (e.g., door/window sealing in cold regions or pipeline sealing for high-temperature equipment).

II. Excellent Chemical Stability

• Strong Corrosion Resistance: It shows good tolerance to acids, alkalis, salt solutions, water vapor, and various chemical media, making it difficult to corrode (e.g., maintaining sealing effects when building curtain walls are exposed to rain or automotive engine compartments come into contact with oil).

• Superior Water Resistance: It does not easily swell or deteriorate after long-term immersion in water, suitable for humid environments such as bathrooms, kitchens, and swimming pools.

III. Superior Physical Properties

• High Elasticity and Flexibility: It has excellent elastic recovery, quickly returning to its original shape after extrusion to ensure a tight seal (e.g., when doors/windows close, the sealing strip fills gaps to prevent air and water leakage).

• Strong Compression Set Resistance: It is not easily deformed after long-term compression, maintaining stable sealing performance and reducing the need for frequent replacement.

• Abrasion and Tear Resistance: With moderate surface hardness (typically Shore hardness 40-90 degrees, adjustable), it is not easily damaged in friction or pulling scenarios, suitable for sealing parts with frequent movement (e.g., the opening/closing areas of car doors).

IV. Good Processing and Installation Adaptability

• Diverse Molding Processes: It can be formed into various shapes (e.g., strip, U-shaped, D-shaped, P-shaped, etc.) through extrusion, compression molding, etc., meeting sealing requirements for structures like doors/windows, curtain walls, and automotive components.

• Convenient Installation: Some products come with self-adhesive backing for direct pasting, or can be fixed by slots or bolts, featuring simple operation and time-saving construction.

• Adjustable Color and Specifications: Pigments can be added to produce different colors (e.g., black, white, gray, etc.), and specifications (e.g., cross-sectional dimensions, length) can be customized to fit diverse scenarios.

V. High Environmental Protection and Safety

• Non-toxic and Odorless: No harmful substances are added to raw materials or during production, complying with environmental standards (e.g., EU RoHS and REACH certifications), suitable for high-safety fields such as the food industry and medical devices.

• Low Volatility: It is not prone to releasing harmful gases in high-temperature environments, being friendly to human health and the environment.

VI. Other Additional Features

• Sound Insulation and Vibration Damping: The elastic material absorbs vibrations and noise, commonly used for sealing car doors and building doors/windows to enhance sound insulation (e.g., reducing outdoor noise from entering rooms).

• Electrical Insulation: It has good insulating properties, applicable for sealing electrical equipment to prevent leakage or short circuits.

Application Scenarios Examples

• Construction Field: Sealing for doors/windows, curtain walls, and skylights to prevent rain and dust infiltration; waterproof sealing for bathrooms and balconies.

• Automotive Industry: Sealing for car doors, windows, and trunks to block wind, rain, and noise; dustproof and oil-proof sealing for engine compartments and gearboxes.

• Industrial Equipment: Sealing for pipelines, storage tanks, and pressure vessels to prevent gas or liquid leakage; vibration damping and sound insulation sealing for mechanical equipment.
