Key features include:

• High resistance to temperature ranges from -40°C to 120°C.
• Excellent sealing capability against oil and grease.
• Widely used in automotive, aerospace, and industrial machinery.

2. Viton Oil Seals

Viton oil seals are engineered from fluorocarbon material, making them ideal for high-temperature and aggressive chemical environments. The demand for Viton seals has surged, with a reported market share increase of 7% in 2023.

Advantages include:

• Operating temperatures of up to 200°C.
• Superior chemical resistance, making them suitable for petroleum-based products.
• Longevity and reduced maintenance costs over time.

3. Silicone Oil Seals

Silicone oil seals offer remarkable temperature stability and are particularly effective in extreme conditions. According to market analysis, silicone seals are projected to witness a growth rate of 6% annually through 2028.

Noteworthy characteristics are:

• High-performance durability in temperatures ranging from -60°C to 230°C.
• Resistance to UV radiation and ozone, prolonging product life.
• Low compression set, ensuring consistent sealing performance.

4. Polyurethane Oil Seals

Polyurethane oil seals are recognized for their outstanding abrasion resistance and strength. The global market for polyurethane oil seals is projected to grow, with an estimated production increase of 10% by 2025.

Key features include:

• Excellent elasticity and resilience over a broad temperature range.
• High resistance to wear, making them ideal for high-speed applications.
• Versatile applications across various industries, particularly in hydraulic cylinders.
