Elastomer Material Selection Guide
Choose rubber compound based on working temperature, oil, UV, flame resistance, emission standard and food contact requirement.
| Material | Key Properties | Limitations | Typical Applications |
|---|---|---|---|
| EPDM | Excellent weather, ozone & water resistance | Not suitable for mineral oil | Outdoor seals, window gaskets, bridge expansion joints |
| Low-Temp EPDM | Good low-temperature flexibility, excellent weather & ozone resistance | Not suitable for mineral oil | Cold-region outdoor seals, refrigeration equipment seals |
| NBR (Nitrile Rubber) | Outstanding oil & fuel resistance | Poor UV / weather resistance | Oil seals, gaskets, mechanical sealing parts |
| Silicone Rubber | Wide temperature -60°C ~ 200°C, odorless, food-grade available | Higher cost, limited resistance to some solvents | Food & medical parts, high-temp oven & appliance seals |
| Neoprene / CR | Balanced flame retardant, oil & weather resistance | Not for continuous high temperature | Fire door seals, marine & industrial equipment |
| NR (Natural Rubber) | High elasticity & tensile strength | Poor oil & ozone resistance | Shock mounts, impact buffer parts |
| Sponge Rubber (Cellular) | Closed-cell, lightweight, good sealing & insulation | Lower mechanical strength | Dust seals, acoustic insulation, weatherstripping |
