Product Description

Cork rubber gasket

Cork rubber gasket features:
1.Good sealing performance: soft texture, can fill irregular surface, achieve effective sealing.
2.Good compression recovery: with excellent compressibility and elasticity, it can be restored to the original state after compression and maintain the sealing effect.
3.Wide temperature range: It can be used in a wide temperature range, such as nitrile cork rubber gaskets can work normally at temperatures from -40 ° C to 130 ° C.
4.Strong corrosion resistance: good resistance to oil, water, acid and alkali and other media, suitable for a variety of working environments.
5.Shock absorption buffer: can effectively alleviate vibration and shock, protect the connecting parts.

Classification and Uses

1.classification

NBR cork: Strong oil resistance, suitable for automotive engines, transformers, and fuel tank flanges. CR cork: Weather-resistant and ozone-resistant, suitable for outdoor electrical equipment, ships, and wind power equipment. General-purpose (SBR) : High cost performance, suitable for household appliances, pipes, and instrument sealing. Automobiles: Valve covers, oil pans, carburetors, air filter gaskets, transformer oil tanks, radiators, high-pressure bushing seals. Gas/fluids: gas meters, pressure reducing valves, valve flanges. General machinery: pumps, valves, fans, box seals and shock-absorbing gaskets.

2.use

Cork rubber gaskets are widely used in the sealing fields of equipment in industries such as chemical engineering, energy, and machinery.

Detailed introduction

The core performance of cork gaskets: 1. Excellent compression and rebound, capable of compensating for unevenness of flanges/contact surfaces; 2. Resistant to mineral oil, low-temperature, anti-aging, and with a high coefficient of friction; 3. It has the functions of shock absorption, heat insulation, sound absorption and electrical insulation. 4. Typical hardness: Shore A 65-80, compression rate 20±5%, rebound ≥75%. 5. The temperature resistance range is usually from -30℃ to 100℃ (adjusted according to the type of adhesive).
