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. | ||
Material | Natural Rubber (NR) | Neoprene (CR) | Polytetrafluoroethylene (PTFE) |
Color | Red, Black, Blue, etc. Customized | ||
Size | Standard&Customized | ||
Density | Typically 0.91-0.93 g/cm³ (low density due to hydrocarbon structure). | Usually 1.2-1.35 g/cm³ (higher density than NR due to chlorine content). | Approximately 2.1-2.3 g/cm³ (very high density, characteristic of fluoropolymers). |
Hardness | Typically 30 - 70 Shore A, with common grades around 50 - 60 Shore A. | Usually 40 - 80 Shore A, with typical values at 50 - 70 Shore A. | Measured by Shore D durometer, approximately 50 - 65 Shore D (harder than rubber, more rigid). |
