Waterborne polyurethane is an environmentally friendly coating material with excellent waterproofing properties, which can be widely used in roof waterproofing projects. Its main applications are as follows:
Roof surface coating: Waterborne polyurethane can be used as a coating material for roof surfaces, forming a strong and durable waterproof membrane that effectively prevents water penetration and leakage problems.

Polyurethane (PU) is a versatile polymer material that has a wide range of applications in various industries. One of the most popular applications of PU is in the textile industry, where it is used as a binder for textile printing, lamination, and surface treatment.
One of the most significant advantages of using PU as a binder for textile printing is its water-based nature. This makes it an eco-friendly and sustainable alternative to traditional solvent-based printing methods. Additionally, the use of water-based PU in textile printing reduces the amount of volatile organic compounds (VOCs) that are released into the air, which is particularly important for indoor printing applications.

Are you looking for an eco-friendly alternative to traditional solvent-based polyurethane resins in automotive interior composites,automotive door trim adhesive? Look no further than water-based polyurethane resin (WPR). With its unique properties, including low VOC emissions and high chemical resistance, water-based automotive polyurethane adhesive is a great option for automotive interior composites.

Since the third quarter of last year, the price trend of polyamide resin has been on an upward trend. What caused the price of polyamide resin to continue to rise?
Let us explain it as below, hope it can be know more about polyamide resin.
As we all know, the main raw material of polyamide resin is oleic acid. With the development of the biodiesel industry, oleic acid raw materials have flooded into the biodiesel market, resulting in a shortage of oleic acid in factories producing polyamide resin.
At the same time, on China loacl market, due to the impact of floods and snowstorms this year, the production of beans and cotton has been reduced, and the raw material of oleic acid has decreased. From the international market due to the impact of The COVID, China’s imports have decreased.
Also many of container are retention on seaport due to seaport staff reduce , and the ship also need more time to arrive one seaport to another seaport,  cargo before pcik up need more long time than before, which has caused domestic oleic acid raw materials to be in short supply.
In the beginning of 2021, various chemical raw materials continue to grow, especially the price of ethylenediamine, the main raw material of polyamide resin, the cost will crazy increasing, and the price can be change by serveral time in one day.
Most professionals generally believe that the price of polyamide resin will continue to rise steadily in the next few months, and it is difficult to reduce polyamide resin cost.
