Incredible Properties And Applications Of Rubber Cork Materials

The market of Cork Rubber Gasket is a vast industry, having many applications with its pure rubber and fibers with its recovery properties. The compressibility and recovery properties of cork combines with the flexibility and elasticity of rubber makes it an excellent sealing application. Its anti vibration properties are applied in the production of cork rubber moulded parts.

The cork rubber has the superior property to rubber or cork agglomerate. Not only the press cut gaskets, cork rubber is use to produce moulded components and gaskets with 3 dimensional shapes. The typical applications of rubber cork gaskets include Electrical Power Transformer, Automotive, aviation, railroad, ship, tractor, petroleum, Electrical Motors and Gas meters. This cork rubber gasket material is widely used in automotive applications such as valve cover; oil pan and timing gear cover gaskets. It cannot be used in strong acid or alkaline conditions as it will be attacked chemically and degrades the cork particles.

The cork rubber material is very cost effective, good for low bolt applications, long shelf life, light weight, less sticking to flanges, easy to handle, resistant to fluid penetration, absorbs vibration and low thermal conductivity. 

Wide variety of Cork Gasket Materials is arrived by combining with EPDM, Synthetic Rubber, Natural Rubber, Neoprene and Nitrile to satisfy the chemical resistance requirement of the gasket.

Cork Rubber as anti-vibration Material: The excellent property of anti vibration isolation is a great advantage in application of many industries such as railways, buildings and other industrial applications. It provides a complete solutions and appropriate materials in manufacture of heavy machine equipments such as compressors, pumps, lifts, turbines, refrigeration and other applications.

Cork Rubber as Noise Vibration Control: The vibration isolation property of elastomers is well improved by adding air in the material. The variable quantity of air added to the elastomer influences it resilience, load bearing capacity, internal damping, vibro acoustic performance and temperature behavior. 

Quality cork granules introduced into elastomers add air to the material very effectively. This fantastic property is achieved through cork which is composed of flexible air filled cells.

The fatigue resistance and creep characteristic can be adjusted with proper control of granulometry, dosage of cork granules and its gradation.

The main advantages of Rubber cork are:
1. Low creep tendency,
2. High flexibility and compressibility
3. Good resistance to oil, fuel and solvent
4. Moderately resists acid, fungus and weather conditions.
5. Low water absorption,
6. Damp at low frequencies
7. Capable of bearing heavy load
8. Life long retaining of unique properties
9. Capable of making into wide range of strips, pads, sheets and thickness
