1. Introduction to Triethylenediamine (TEDA)

1.1 What is triethylenediamine (TEDA)?

Triethylenediamine (TEDA) is an organic compound with the chemical formula C6H12N2. It is a colorless liquid with a strong ammonia odor and is widely used in the production of polyurethane foam. As an efficient catalyst, TEDA can accelerate the polyurethane reaction and improve the physical properties of foam.

1.2 Chemical properties of TEDA

• Molecular formula: C6H12N2
• Molecular Weight: 112.17 g/mol
• Boiling point: 174°C
• Density: 0.92 g/cm³
• Solubilization: Easy to soluble in water and organic solvents

1.3 Application of TEDA in polyurethane foam

TEDA is mainly used in the production of polyurethane foam. As a catalyst, it can accelerate the reaction between isocyanate and polyol to form a stable foam structure. This foam structure has excellent elasticity and durability and is widely used in automotive seats, furniture, mattresses and other fields.

2. Application of TEDA in car seat manufacturing

2.1 Improve seat comfort

2.1.1 Elasticity and Support

TEDA as a catalyst can significantly improve the elasticity and supportability of polyurethane foam. This foam material can be automatically adjusted according to the weight and shape of the human body, providing uniform support and reducing the fatigue of long-term rides.

Support force (N)	250	350
Compressive Strength (MPa)	0.6	0.9

3.3 Commercial Vehicle Seats

Commercial vehicle seats need to withstand higher working strength and longer service life. TEDA enhanced polyurethane foam shows excellent durability and anti-aging properties in commercial vehicle seat manufacturing, which can meet the special needs of commercial vehicles.

parameters	Traditional bubble	TEDA Enhanced Foam
Service life (years)	6	10
Anti-aging properties (years)	4	8

IV. Future development trends of TEDA in car seat manufacturing

4.1 Environmentally friendly TEDA

With the increase in environmental awareness, TEDA production will pay more attention to environmental protection and sustainability in the future. Environmentally friendly TEDA can not only reduce environmental pollution during production, but also improve the recycling rate of polyurethane foam.

parameters	Traditional TEDA	Environmental TEDA
Environmental performance (level)	3	5
Recycling and utilization rate (%)	50	80

4.2 Intelligent TEDA

In the future, TEDA may combine with smart materials to develop polyurethane foams with self-regulating functions. This intelligent foam can automatically adjust the hardness and support according to the occupant's weight and posture, providing a more personalized and comfortable experience.

parameters	Traditional TEDA	Intelligent TEDA
Self-adjustment function	None	Yes
Personal Comfort (1-10)	7	10

4.3 High-performance TEDA

As the automotive industry continues to improve its material performance requirements, TEDA may further optimize its chemical structure in the future and develop higher performance catalysts. This high-performance TEDA can significantly improve the physical properties of polyurethane foam and meet the needs of higher-end car seat manufacturing.
