Synthetic fibres such as polyester are used for the production and optimal function of different battery types. Fibres in battery pastes contribute to the mechanical stabilization of functional layers, which increase the durability and improve the processability. A battery separator is a porous layer that separates the positive and negative charged electrodes.

• Separators for various rechargeable and non-rechargeable batteries and accumulators
• Pastes in lead-acid batteries
• Pasting paper for the production of the lead-acid batteries
