Cork gaskets are widely used in transformers to create secure seals between flanges and covers. These areas require materials that can endure mechanical stress, thermal expansion and the presence of transformer oils. By combining cork with rubber, we enhance the flexibility and resistance of the material, providing a d…

Cork and rubber gaskets have several advantages over other sealing options on the market. and On the one hand, its high sealing capacity requires less sealing load for effective sealing. In this way, the screws used can be smaller, which results in greater stability and reduces the degree of vibration of the device. ​ …

Thickness reduction that occurs with a given gasket material at various known applied external loads, thereby establishing a load/compression curve.

For example, in the case of TD1049, a cork-based material used as a gasket and recommended for most transformer oils, a roll with typical dimensions of 1020 mm x 6 mm x 11 m has a carbon footprint of -37 kg CO₂ per roll.  In vibration control solutions, using VC2100 material, applied as a vibration pad, a plate with di…

Our range of engineered sealing materials is based on soft gasket technology, specifically designed and tested to withstand stringent application needs in diverse environments while providing effective final product customization and manufacturing options. The fact that cork has a closed cell structure, filled with air…
