Material | Silicone Rubber (VMQ) | Ethylene Propylene Diene Monomer (EPDM) | Polyurethane Rubber (PU) |
Color | Red, Black, Blue, etc. Customized | ||
Size | Standard&Customized | ||
Density | Ranges from 0.96-1.25 g/cm³ (lower density than many rubbers; pure silicone: ~0.96-1.05 g/cm³). | Generally 0.86-0.95 g/cm³ (one of the lowest densities among common rubbers). | Hardness-dependent density: 1.1-1.25 g/cm³ for common grades. |
Hardness | Ranges from 20 - 80 Shore A, with common medical/food grades at 40 - 60 Shore A. | Generally 40 - 90 Shore A, with standard industrial applications at 50 - 80 Shore A. | Hardness spans 60 - 95 Shore A, often used at 70 - 90 Shore A for high - wear resistance. |
Temperature | -60°C to +200°C (-76°F to +392°F) | -50°C to +150°C (-58°F to +302°F) | -30°C to +80°C (-22°F to +176°F) |

Advantages | 1.Extreme temperature tolerance (-60°C to +200°C, short-term up to +260°C). 2.Biocompatible and non-toxic, suitable for medical and food applications. 3.High flexibility at low temperatures. Good electrical insulation properties. | 1.Excellent resistance to ozone, UV radiation, and weathering. 2.Superior water and steam resistance. 3.Low density and good electrical insulation. 4.Cost-effective for outdoor and marine applications. | 1. Extremely high abrasion and tear resistance. 2.High load-bearing capacity and mechanical strength. 3.Good resistance to oils and greases (moderate compared to NBR). 4.Ideal for dynamic seals in high-wear environments. |
Application | Medical devices (e.g., surgical instruments, tubing); Food processing equipment; Pharmaceutical machinery; High/low-temperature seals (e.g., oven doors, refrigeration systems) Electrical insulation. | Automotive weatherstripping; Window seals; Water supply systems; Steam pipes; Electrical cables; Outdoor applications requiring ozone/UV resistance. | Hydraulic cylinders; Pneumatic systems; Conveyor belts; Mining equipment; High-wear applications like piston seals and rod seals. |
Storage& Maintenance | 1. Regular Inspection: Periodically check the O-ring for signs of wear, such as abrasion on the surface, and aging, which may present as cracking, hardening, or discoloration. 2. Timely Replacement: Replace O-rings immediately if they are damaged, deformed, or show signs of aging. A defective O-ring can no longer ensure proper sealing performance. 3. Exposure Avoidance: Prevent O-rings from being exposed to harsh environments for extended periods. | ||
