Delayed low odor amine catalyst LED-204: Achieving efficient and low VOC emissions polyurethane solutions
Introduction
Polyurethane materials have become one of the indispensable materials in modern industry due to their excellent physical properties and wide application fields. However, traditional polyurethane production is often accompanied by emissions of highly volatile organic compounds (VOCs), which not only pollutes the environment, but also can have adverse effects on the health of operators. To solve this problem, the delayed low-odor amine catalyst LED-204 came into being. This article will introduce the product characteristics, application fields, technical parameters and their advantages in polyurethane production in detail.
1. Product characteristics of LED-204
1.1 Low odor and low VOC emissions
LED-204 is an amine catalyst specially designed for polyurethane production. Its major feature is its low odor and low VOC emissions. Traditional amine catalysts release irritating odors during the reaction process, while LED-204 significantly reduces the generation of odors by optimizing the molecular structure and reducing VOC emissions, which meets modern environmental protection requirements.
1.2 Delayed catalytic effect
LED-204 has a delayed catalytic effect, which means it does not work immediately at the beginning of the polyurethane reaction, but starts to accelerate the reaction only after a certain period of time. This characteristic makes polyurethane materials have better flowability during the production process, facilitate the filling of complex molds, and reduce the generation of bubbles and defects.
1.3 High-efficiency catalytic performance
Although LED-204 has a delayed catalytic effect, its catalytic efficiency is not inferior to that of traditional catalysts. Under appropriate temperature and time conditions, LED-204 can significantly accelerate the reaction speed of polyurethane, shorten the production cycle, and improve production efficiency.
1.4 Wide applicability
LED-204 is suitable for a variety of polyurethane systems, including soft foams, rigid foams, elastomers, coatings and adhesives. Its wide applicability makes LED-204 a universal catalyst in polyurethane production.
2. Application fields of LED-204
2.1 Soft polyurethane foam
Soft polyurethane foam is widely used in furniture, mattresses, car seats and other fields. The application of LED-204 in soft foam can significantly improve the open-cell structure of the foam and improve the comfort and durability of the foam.
2.2 Rigid polyurethane foam
Rough polyurethane foam is mainly used in the fields of building insulation, cold chain transportation and industrial insulation. The application of LED-204 in rigid foam can improve the closed cell rate of foam, enhance thermal insulation performance, and reduce VOC emissions, which meets the requirements of green buildings..
2.3 Polyurethane elastomer
Polyurethane elastomers are widely used in soles, seals, tires and other fields. The application of LED-204 in elastomers can improve the mechanical properties and wear resistance of materials while reducing odor and VOC emissions during production.
2.4 Polyurethane coatings and adhesives
Polyurethane coatings and adhesives are widely used in construction, automobile, electronics and other fields. The application of LED-204 in coatings and adhesives can improve the adhesion and durability of the coating while reducing odor and VOC emissions during construction.
