420Gasket Material With Controlled Swell Properties
| Gasket Material With Controlled Swell Properties | |
| Technical Values | |
| Material Model | CSP-01/03 |
| Basis | Aramid fibers, inorganic fillers，Synthetic or mineral fibers |
| Binder | NBR-Nitrile Butadiene Rubber |
| Characteristic | Description |
| 1. CSP is a soft cushion material with controllable expansion characteristics, which can absorb oil. | |
| 2. It is specially designed for sealing at low surface stress on rough or uneven sealing flanges. The controled swelling of gasket material in such case compensate the loss of specific surface pressure in application. | |
| 3. They have different thermomechanical properties and chemical resistance to endure at different loadings, even the most demanding conditions. | |
| Applicable Medium | Fuel, lubricating oil, transmission oil, engine oil, air, water, low acidity, low alkalinity, etc |
| Application Field | Gearboxes, Diesel Engines, Air Compressors, Gasoline Engines, Motorcycles, Construction Machinery, General Machinery, Etc. |
