Product Description

PU, which is short for polyurethane, is a new kind of organic polymer material, which is synthesized from isocyanate (monomer) and hydroxyl compound., the main chain contains - NHCOO - repeating structural units of a class of polymers.English name is polyurethane, abbreviated PU.Polyurethane is praised as "the fifth largest plastic", because of its excellent performance, it is widely used in many fields of national economy.The products are applied in light industry, chemical industry, electronics, textile, medical treatment, construction, building materials, automobile, national defense, aerospace, aviation and so on.

Polyurethane material contains strong polar carbamate group, insoluble in non-polar groups, so it has good oil resistance, toughness, abrasion resistance, aging resistance and adhesion, excellent wear resistance, flexural resistance;Excellent shock absorption and skid resistance;Good temperature resistance;Good chemical resistance, etc.Materials suitable for a wide temperature range (-50 ~ 150℃) can be prepared from different raw materials, including elastomer, thermoplastic resin and thermosetting resin.Not resistant to hydrolysis at high temperature, also not resistant to alkaline medium.

 

 

Made of polyurethane material for mining vibrating screen, its advantages are as follows:

1. Good screening effect: the screen is woven from round polyurethane bars, with good elasticity, avoiding the adhesion of damp particles, good cleanliness, and not easy to plug holes;

2. Energy saving and environmental protection: polyurethane screen has advantages of high efficiency, energy saving and environmental protection due to its light weight, small dynamic load, small power consumption, increased handling capacity, improved production efficiency and low noise.

3. Long service life: the unique production process of polyurethane screen makes only a little friction between materials and screen, and the impact force is greatly reduced.
