NBR Foam Rubber Strip is an elastic sealing material made of nitrile rubber (NBR) as the main raw material through a foaming process. It has excellent oil resistance, elasticity and cushioning performance and is widely used in industry, automobiles, construction and other fields.
Characteristics | Description |
| Oil resistance | Excellent resistance to mineral oil, fuel, and lubricating oil, suitable for automobiles and mechanical seals. |
Good elasticity | High resilience, suitable for shock absorption and cushioning applications |
Aging resistance | Ozone resistance, UV resistance (some formulas can be used outdoors). |
Flame retardancy | UL94 HB or V-0 level can be achieved by adding flame retardants |
Temperature resistance | range -30℃ ~ 100℃ (special formulas can reach 120℃) |
Waterproof sealing | Closed-cell structure, moisture-proof, dust-proof, and sound-proof |
Customizable hardness | Usually 10~35 Shore A, can be adjusted according to needs. |
