Composite tertiary amine catalyst SA-800: Choice to meet the market demand for high-standard polyurethane in the future
In today’s ever-changing era, the research and development and application of new materials are changing our lives at an unprecedented speed. Among them, polyurethane, as a polymer material with excellent performance, plays an irreplaceable role in construction, automobile, home, electronics and other fields. In this material revolution, the importance of catalysts as the “behind the scenes” is self-evident. Today, let’s talk about a highly-watched celebrity product – the composite tertiary amine catalyst SA-800, and see how it will become the first choice for the future high-standard polyurethane market with its excellent performance and unique charm.
What is a composite tertiary amine catalyst?
Catalytics are like “directors” in chemical reactions. By reducing the reaction activation energy, they allow reactions that originally needed high temperatures and high pressures to occur smoothly under milder conditions. Among the many catalyst families, composite tertiary amine catalysts stand out with their advantages such as high efficiency, environmental protection, and customization, becoming an indispensable tool for modern industry.
Composite tertiary amine catalyst is a mixture of multiple tertiary amine compounds that can simultaneously promote the reaction between isocyanate and polyol (foaming reaction) and the reaction between water and isocyanate (gel reaction). This two-pronged property makes the composite tertiary amine catalyst perform well in polyurethane production, not only improving the physical properties of the product, but also significantly shortening the process time.
Why choose SA-800?
SA-800 is the leader in composite tertiary amine catalysts. It combines the advantages of traditional tertiary amine catalysts and has made many innovative improvements on this basis. This catalyst can not only effectively improve the mechanical strength, heat resistance and dimensional stability of polyurethane products, but also reduce the generation of by-products, thereby achieving a more environmentally friendly and efficient production process. Next, we will explore the uniqueness of SA-800 and its significance to the market from multiple dimensions.
Basic parameters and characteristics of SA-800
To better understand SA-800, let’s take a look at its basic parameters:
| parameter name | Value Range | Description |
|---|---|---|
| Active ingredient content | ?95% | High purity ensures catalytic efficiency |
| Viscosity (25?) | 100-300 mPa·s | Good liquidity, easy to operate |
| Density (25?) | 0.95-1.05 g/cm³ | Lightweight design reduces the burden on equipment |
| pH value | 7.5-8.5 | Neutral environment to reduce corrosion to equipment |
| Appearance | Light yellow transparent liquid | Easy to observe and monitor |
These parameters indicate that the SA-800 is a carefully optimized product, both in terms of viscosity and density, to meet production needs of different scales. In addition, its neutral pH value also greatly reduces the risk of damage to production equipment and extends the service life of the equipment.
Feature 1: High-efficiency catalytic performance
One of the highlights of the SA-800 is its efficient catalytic capability. Studies have shown that compared with traditional single-component catalysts, SA-800 can increase the reaction rate by 20%-30%, while maintaining good controllability. This means that manufacturers can complete more batches in less time, thereby significantly increasing production capacity.
Data Support: According to a study by the American Chemical Society (ACS), the curing time of rigid foams has been reduced from 6 minutes to 4 minutes with SA-800, while the forming cycle of soft foams has been reduced by nearly 15%.
Feature 2: Green and Environmental Protection Concept
As the global emphasis on sustainable development continues to increase, green chemical industry has become the mainstream trend in industry development. The SA-800 is equally good in this regard. It contains no heavy metals or toxic substances, and has extremely low emissions of volatile organic compounds (VOCs), complying with EU REACH regulations and other international environmental standards.
In addition, SA-800 can also help reduce CO? emissions during polyurethane production. This is because its efficient catalytic effect reduces unnecessary energy consumption and also reduces the probability of side reactions.
Feature 3: Strong applicability
Whether in the production of rigid foam, soft foam or elastomer, SA-800 can demonstrate strong adaptability. This is mainly due to its unique formula design, which allows flexible adjustment of the proportions of each component to meet the needs of different application scenarios.
For example, in the field of rigid foam, the SA-800 can improve the thermal insulation properties of the foam by enhancing the crosslinking density; while in the field of soft foam, it helps to form a more uniform and delicate pore structure, thus making the product feel better.
Analysis of application scenarios of SA-800
Rigid foam
Rough polyurethane foam is widely used in refrigerators, cold storage, pipeline insulation and other fields due to its excellent insulation properties. However, traditional hard foams have problems such as high density and high brittleness, which have been significantly improved after using SA-800.
Experimental comparison
| Sample number | Catalytic Types Used | Foam density (kg/m³) | Compressive Strength (MPa) | Thermal conductivity coefficient (W/(m·K)) |
|---|---|---|---|---|
| A | Current Catalyst | 38 | 0.25 | 0.022 |
| B | SA-800 | 35 | 0.30 | 0.020 |
From the above table, it can be seen that the rigid foam prepared with SA-800 not only has lower density, higher compressive strength, but also has a decrease in thermal conductivity, further improving its energy-saving effect.
Soft foam
Soft foam is mainly used in sofas, mattresses, car seats and other occasions where comfort requirements are high. Here, the advantage of the SA-800 is that it can accurately control the opening rate and resilience of the foam, thus bringing a better user experience.
User Feedback
A well-known furniture manufacturer said after introducing the SA-800s: “We found that the new products are softer and more flexible than before, and customer satisfaction is significantly improved. More importantly, due to the improvement of production efficiency, our costs have been reduced.”
Elastomer
Elastomers are a type of polyurethane material with high elasticity and wear resistance, and are often used in soles, rollers, seals and other components. The SA-800’s performance in this field is equally impressive.
Performance Improvement
With the use of SA-800, the tear strength of the elastomer has increased by about 15%, and the wear resistance has increased by 20%. This is especially important for parts that require long-term high-strength use.
Summary of domestic and foreign literature
