MDI high rebound screen panel is made of high-quality polyurethane material (diphenylmethane diisocyanate) combined with a metal framework, offering excellent wear resistance, high rebound screening, reduced power consumption, and many other advantages. Whether in wet screening or under high-frequency vibration conditions, it can maintain high screening accuracy, extend the service life of the screen mesh and reduce downtime and replacement frequency, making it an ideal choice for efficient screening in the mining and chemical industries.
