Our Rubber balls can be used to clean screens. The rubber balls are applied to the material to be screened, and their bouncing activity creates frequent collisions with other balls indefinitely, the material to be screened and the screen itself stays clean. Such repeated movements make the passages in the screen frame open. We use natural rubber material which is characterized by low abrasion and high rebound elasticity to overcome the resulting abrasion pressure and to ensure the necessary bounce characteristics. This ensures the best outcomes possible during the cleaning process. Rubber balls have good resistance in contact with water, diluted acids and basis, alcohols. The behaviour of rubber balls is not suitable in contact with steam, oils, petrol and aromatic hydrocarbons, oxygen and ozone and in contact with ketone
