Degradation of polyurethane elastomers (PUEs) and their stabilizers
Thermal oxygen degradation of polyurethane elastomers (PUEs) and its stabilizers Thermo-oxidative degradation is a free radical chain process initiated by atmospheric oxygen. For thermal oxygen degradation, polyester-based polyurethane elastomers (PUEs) are more stable than polyether-based polyurethane elastomers (PUEs) due to that the cohesive energy of the ester group is greater than that of the ether […]
Application of polycarbodiimide cross linking agent in water-based polyurethane (PU)
Polyurethane polymer materials have the advantages of wear resistance, high temperature resistance, good adhesion, easy processing and favorable price. Water-based polyurethane (WPU) uses water as the dispersing medium, avoiding the disadvantages of traditional organic solvents such as serious pollution and health hazards, while saving a large amount of organic solvents and greatly reducing costs. Due […]
Improve the shelf life of PLA straws? Hydrolysis-resistant modification is very important!
PLA is one of the mainstream bio-based and biodegradable plastics with mature industrialization, large production volume and wide application. PLA has high mechanical strength and transparency, but its poor heat resistance, toughness and durability limit the application. For this reason, it is necessary to improve the aging resistance of PLA in terms of hydrolysis from […]
Hydrolysis-resistant PBT solves the problem of water decomposition and temperature resistance in the production of automotive electronic components
With the maturity of new energy vehicles and autonomous driving technology, the market demand for automotive electronic materials is increasing. For example, the traditional automotive electronic materials basically have no flame retardant requirements, while the electronic materials used in new energy vehicles require flame retardant level. This presents a problem to vehicle manufacturers, automotive electronic […]
Application of carbodiimide anti-hydrolysis stabilizer in PU leather
Introduction of PU leather Polyurethane synthetic leather (PU leather) is the most ideal material in the world to replace natural leather products, mainly used in shoes, clothing, bags, balls, furniture, automobiles, flexible containers, pipes, conveyor belts, canvas and other fields. As a kind of thermoplastic elastomer, PU leather has the advantages of oil resistance, wear […]

Application of anti-hydrolysis agent in PBAT
PBAT, with the full name polybutylene adipate terephthalate, has the following structural formula. It belongs to petrochemical-based biodegradable plastics and has become one of the very active degradable materials in research and market application at present. PBAT is a thermoplastic biodegradable plastic with excellent biodegradability and is often used as a blend with PLA for […]
Application of carbodiimide anti-hydrolysis agent in PLA
Polylactic acid (PLA), as a completely degradable polymer material, is called “green plastic” and has good biodegradability, which can be completely degraded by microorganisms in nature after use, eventually producing carbon dioxide and water, without polluting the environment. PLA also has good mechanical and physical properties and is suitable for various processing methods such as […]
Application of anti-hydrolysis agent in PET polyester monofilament for paper making clothing industry
What is polyester monofilament? Polyester monofilament is made from PET chips. The chips are spun by melt method, then cooled and shaped in a bath, and finally drawn and thermoformed to get monofilament. Polyester monofilament is characterized by high strength, good toughness, dimensional stability, high temperature and low-temperature resistance, and chemical stability to acids and […]
