Description on polyurethane and its applications in China2019.07.17

Polyurethane (PUR and PU) is a polymer composed of organic units joined by carbamate (urethane) links. It has the following characteristic:


  • Wide Range of Hardness: The hardness range of polyurethane can be manufactured from 20 SHORE A to 85 SHORE D
  • High Load Bearing Capacity: Polyurethane has a high load capacity in both tension and compression
  • Good Flexibility: Polyurethanes perform very well when used in high flex fatigue applications
  • Abrasion Resistance: Polyurethanes have strong cohesive energy, so they have good wear-resisting property
  • Tear Resistance: Polyurethanes possess high tear resistance
  • Resistance to Water, Oil & Grease: Polyurethanes material will remain stable in water, oil and grease
  • Good Electrical Insulating Properties: Polyurethanes has good electrical insulating characteristics 
  • Strong Bonding Properties: Polyurethane bonds to a wide range of materials during the manufacturing process
  • Resistance to Extreme Temperature: Polyurethane has good resistance to extreme temperature and performs very well in harsh environmental conditions 
  • Short Production Lead Times: Compared to conventional thermoplastic materials polyurethane has a relatively short production lead times


Thanks to these excellent properties, polyurethane products are widely used in various sectors, such as the manufacture of polyurethane foam, sizing agent of the synthetic leather and painting, which account for a large proportion with the share of 39.19%, 17.12% and 16.09% respectively. 



From 2014 to 2017, China's polyurethane output and consumption quantity have both experienced a steady increase. In 2017, China’s polyurethane output reached 11.9 million tons and the consumption rose to 11.1 million tons, increasing by 23% and 15.6% from 2014 respectively.
