However, with the increasing demand for high-performance and environmentally friendly materials in the market, traditional polyurethane production technology has gradually shown limitations. Especially in complex foaming processes, how to achieve precise reaction control and optimize product performance has become a core issue of industry concern. Against this background, the delayed amine catalyst 1027 stands out with its unique catalytic characteristics and excellent application performance, becoming an important technology leading the development of the polyurethane industry.
Retardant amine catalyst 1027 is a highly efficient catalyst specially designed for the polyurethane foaming process. By precisely controlling the reaction rate between isocyanate and polyol, it can not only significantly improve the physical properties of foam products, but also effectively reduce energy consumption and reduce by-product generation. What is unique about this catalyst is its “delay” nature—that is, it maintains low activity at the beginning of the reaction, followed by a gradual release of the catalytic capacity to ensure uniform reaction. This feature makes 1027 particularly suitable for application scenarios where foaming time and density distribution need to be strictly controlled, such as rigid foam insulation boards, soft foam seats, and sprayed foam.
This article will deeply explore the technical characteristics of delayed amine catalyst 1027 and its application value in the polyurethane industry from multiple angles. First, we will introduce the basic principles and core advantages of this catalyst in detail; second, analyze its performance in different application scenarios based on specific cases; then, look forward to its development trend in the future market and discuss possible challenges and solutions. Through the comprehensive analysis of this article, readers can not only deeply understand the technical connotation of delayed amine catalyst 1027, but also feel the transformative power brought by this cutting-edge technology to the polyurethane industry.
What is delayed amine catalyst 1027?
Definition and Classification
Retardant amine catalyst 1027 is a functional catalyst designed specifically for the polyurethane foaming process. From a chemical structure point of view, it belongs to a type of tertiary amine compound, usually composed of specific organic amine groups combined with other functional additives. The core feature of this type of catalyst is that it can exhibit time-dependent catalytic behavior during the reaction process, that is, inhibit the reaction rate in the initial stage and gradually release the catalytic action in the subsequent stage, thereby achieving precise control of the entire foaming process.
Depending on its functional positioning, retarded amine catalysts can be further subdivided into two categories: retarded hydrolysis catalysts and retarded crosslinked catalysts. The former is mainly used to promote the reverse reaction between isocyanate and water.It should be a carbon dioxide gas to drive foam expansion; the latter focuses on regulating the crosslinking reaction between polyols and isocyanates to optimize the mechanical properties and durability of the foam. The 1027 catalyst performs well in both aspects and is therefore widely used in the production of various polyurethane foam products.
Core components and working principles
The core components of delayed amine catalyst 1027 mainly include the following parts:
-
Active Amine
The main catalyst is a key component of 1027, usually a specially modified tertiary amine compound such as dimethylamine (DMEA) or triamine (TEA). These compounds are highly alkaline and can effectively promote the reaction between isocyanate and polyol or water. -
Retardant Agent
The function of the retardant agent is to temporarily inhibit the activity of the main catalyst and maintain a low level of catalytic efficiency at the beginning of the reaction. Common retarding agents include fatty acid esters, siloxane derivatives or certain weakly acidic compounds that achieve this effect by forming a stable complex with the main catalyst. -
Stabilizer
Stabilizers are used to improve the overall stability of the catalyst and prevent it from decomposing or failing during storage or transportation. This type of substance is usually some antioxidant or metal chelating agent. -
Additives
To meet the needs of specific application scenarios, the 1027 catalyst may also contain some functional additives, such as foam stabilizers, antistatic agents or flame retardants.
Working Principle
When the delayed amine catalyst 1027 is introduced into the polyurethane foaming system, its work flow can be roughly divided into the following stages:
-
Initial suppression phase
At the beginning of the reaction, the retardant forms a stable complex with the main catalyst, limiting the latter’s catalytic activity. At this time, the reaction rate of isocyanate with polyol or water is low, which helps to control the initial expansion rate of the foam. -
Step Release Stage
As the reaction temperature increases or the system pH changes, the retardant gradually dissociates, releasing the active site of the main catalyst. This process usually occurs in the middle of the reaction, ensuring that the foam can fully expand and achieve the idealDensity distribution. -
Final solidification stage
In the late stage of the reaction, the main catalyst is completely released and plays a large catalytic role, promoting the completion of the cross-linking reaction between isocyanate and polyol, forming a stable three-dimensional network structure.
Through the above mechanism, the delayed amine catalyst 1027 achieves dynamic regulation of the entire foaming process, which not only avoids foam collapse caused by excessive reaction, but also prevents bubble instability caused by excessive reaction.
Technical Features and Advantages
Compared with traditional catalysts, the delayed amine catalyst 1027 has the following significant technical features and advantages:
| Features/Advantages | Description |
|---|---|
| Delayed Catalytic Characteristics | It can effectively control the rate of the initial reaction and avoid excessive expansion or collapse of the foam |

These characteristics make the 1027 catalyst show extremely high flexibility and adaptability in practical applications, making it an ideal choice in modern polyurethane production processes.
Main application fields of delayed amine catalyst 1027
Retardant amine catalyst 1027 has been widely used in many polyurethane-related fields due to its excellent performance and technical advantages. The following are several typical application scenarios and their specific manifestations:
1. Rough polyurethane foam
Rigid Polyurethane Foam (RPUF) is a widely used building insulation, high-performance materials in the fields of refrigeration equipment and home appliances. Since it requires rapid foaming and curing in a short time, while ensuring the density uniformity and mechanical strength of the foam, the requirements for catalysts are extremely demanding.
Application Features
- Fast foaming: 1027 catalyst can effectively promote the reaction between isocyanate and water, and generate enough carbon dioxide gas to drive foam expansion.
- uniform density distribution: Through delaying catalytic characteristics, ensure that the foaming rate of the foam in different areas is consistent, and avoid local collapse or over-tightness.
- Excellent thermal insulation performance: The final hard foam has low thermal conductivity and high closed cell rate, making it ideal for use as a thermal insulation material.
Practical Cases
The rigid polyurethane insulation board produced by a well-known building materials company using 1027 catalyst has a thermal conductivity of only 0.022 W/(m·K), far lower than the industry average. In addition, the product has excellent dimensional stability and weather resistance during long-term use, winning wide recognition from the market.
2. Soft polyurethane foam
Flexible Polyurethane Foam (FPUF) is mainly used in furniture, mattresses and car seats, and requires the foam to have a soft feel and good resilience. In this application scenario, the 1027 catalyst also plays an important role.
Application Features
- Precisely control foaming time: By delaying catalytic characteristics, ensure that the foam expands fully in the mold and then cures, avoiding defects caused by premature solidification.
- Optimize mechanical properties: Promote the cross-linking reaction between polyol and isocyanate, giving the foam higher compression and tear strength.
- Environmental Compliance: 1027 catalyst does not contain any volatile organic compounds (VOCs) and complies with strict environmental regulations.

A internationally renowned automaker has used 1027 catalysts in the production of seats for its high-end models. The test results show that the soft foam prepared with this catalyst not only feels more comfortable to the touch, but also maintains its original shape and performance after repeated compression, which significantly improves the user’s riding experience.
3. Spray polyurethane foam
Spray Polyurethane Foam (SPF) is widely used in roof waterproofing, wall insulation and pipeline protection due to its convenient construction and strong applicability. However, the spraying process puts higher requirements on the response speed and stability of the catalyst.
Application Features
- Instant foaming capability: 1027 catalyst can quickly start the foaming reaction at the moment of spraying to ensure that the foam can adhere to the surface of the substrate in time.
- Strong adhesion: By adjusting the crosslinking reaction rate, the bonding strength between the foam and the substrate is enhanced to prevent shedding or cracking.
- Excellent weather resistance: The final foam has strong UV resistance and aging resistance, and is suitable for long-term outdoor use.
Practical Cases
A large construction engineering company used a spray foam system based on 1027 catalyst in a high-rise building exterior wall insulation project. The results show that the system not only has high construction efficiency, but also exhibits excellent thermal insulation and waterproofing performance under extreme climate conditions, greatly reducing the energy consumption of the building.
