Polyurethane encapsulation also has certain disadvantages: large internal heat generation and general high temperature resistance. The normal use temperature range is -40~120 ℃. If long-term effects are required under high-frequency oscillation conditions or high-temperature conditions, corresponding modification measures must be taken in structural design or formulation.

Drum coating can choose different materials, such as rubber, silicone, plastic, etc., but is widely respected polyurethane material (PUR). Polyurethane elastomers have good wear resistance, usually three to five times that of rubber, and are called wear-resistant rubber. Through the correct process of integrated molding, long-term use without degumming. At the same time, oil resistance, water resistance, corrosion resistance, can be used in a variety of working environment.

Polyurethane rollers are made from polyisocyanates and polyether polyols or polyester polyols
