New breakthroughs have been made in the development of polyurethane materials that are closely related to life
.
"The flame-retardant and environmentally friendly high-performance polyurethane material we developed broke the monopoly of foreign famous brands in environmental protection, flame-retardant and high-end polyurethane materials
Flame retardant and environmentally friendly high-performance polyurethane materials have broken the monopoly of foreign famous brands in environmental protection, flame retardant and high-end polyurethane materials
"The polyurethane flexible foam developed by Liming Institute can be applied to seats, cushions and headrests of aircraft, trains, automobiles and other transportation vehicles due to its excellent characteristics
.
We have become a polyurethane foam for interior parts such as Yutong T7 car seats.
According to reports, in order to realize the transformation of Yutong bus T7 from ordinary interiors to environmentally friendly boutique interiors, the company's polyurethane material development projects have combined a material with a cavity structure.
The hydrophobic cavity can envelop organic molecules and inhibit benzene.
The volatilization of compounds and aldehydes reduces the total volatile organic compounds (TVOC) by 47%
.
They also combined the low odor fast response system formulation technology to give the product a foam odor rating better than 3.
At the same time, the project team independently designed and synthesized a nitrogen-containing structural flame-retardant polyether polyol-polyurea polyol
.
The polyol does not contain halogen, and achieves flame retardant effect through nitrogen element.
It is worth mentioning that the project team developed a composite polyurethane memory foam technology
.
Using self-designed polyether polyol with high ethylene oxide content as the main component, by screening cell openers and matching high-activity foam stabilizers, they obtained low temperature sensitive products with a density of less than 55 kg/m3 and an oxygen index of more than 25%.
It is worth mentioning that the project team developed a composite polyurethane memory foam technology
"The flame-retardant and environmentally friendly high-performance polyurethane material has been recognized by the industry.
A total of 7 invention patents have been declared for this project, 5 of which have been authorized and won the third prize of China Petroleum and Chemical Industry Federation Science and Technology Progress Award
.
In the past three years, the company has accumulated More than 17,000 tons of products are sold, and the economic benefits are significant
