Round belts are also called polyurethane round belts. Round belts that can be connected are usually made of PU. PU is the abbreviation of Polyurethane. The Chinese name is polyurethane for short. Using thermoplastic high-quality polyurethane material, you only need to modify the formula to obtain different physical properties such as density, elasticity, and rigidity. At present, it has been widely used to replace glass fiber insulation materials, wood, traditional rubber products, etc.;

PU round belt characteristics:

(1) Smooth transmission, with buffering and shock absorption capabilities, and low noise;
(2) The transmission is accurate, there is no sliding during work, and it has a constant transmission ratio;

(3) Convenient maintenance, no need for lubrication, and low maintenance cost;

(4) It is not easy to break at low temperature, and the temperature resistance range is -35℃ to 80℃; used as a temperature of 20℃-60℃;

(5) It can be used for long-distance transmission, and the center distance can reach more than 10m.

(6) It has excellent flex resistance, wear resistance, impact resistance, oil resistance, water resistance, chemical resistance, plasticizers, easy connection, installation, and long service life;

(7) The speed ratio range is large, generally up to 10, and the linear speed can reach 50m/s, with a large power transmission range, up to several watts to several hundred kilowatts;

(8) Nylon core and steel core can be added; hardness range: Shore A hardness 80A to 95A; elongation: 5-8%<8;5-6%>8; extremely high tensile strength and tensile strength;

(9) The transmission efficiency is high, up to 0.98, and the energy saving effect is obvious;

Round conveyor belts use imported PU (polyurethane) as raw materials, generally divided into PU smooth round belts and PU rough round belts.

The color of the glossy PU round belt is generally orange, with a smooth surface, uniform finish and bright color.
The color of PU rough round belt is generally dark green and imported light green, rough surface, uniform particles, and comfortable hand feeling.

In order to meet the various production requirements of customers to a greater extent, we can produce PU round belts in various colors and models according to customer procurement requirements. The specifications can be mass-produced from 2mm-30mm.

PU round belt has extremely high tensile strength, tensile strength, abrasion resistance, impact resistance, oil resistance, water resistance, chemical resistance, no plasticizer, wide temperature range, not easy to elongate, easy to weld, easy to install, and longevity Long and other characteristics, suitable for packaging machines, printing machines, textile machines, transmission wheels, ceramic tiles, cement tiles, floor tiles, food, wooden products, cans, newspapers, printed materials, etc.
