Basic Characteristics of Polyurethane Foaming Emineral Catalyst
1.1 Definition and composition of polyurethane foam
Polyurethane foam is a polymer material produced by chemical reactions such as polyols, isocyanates and catalysts. It has the characteristics of lightweight, softness, good elasticity and excellent thermal insulation performance, and is widely used in furniture, automobiles, construction and other fields.
1.2 The role of amine catalyst
Amine catalysts play a crucial role in the formation of polyurethane foam. It can accelerate the reaction of polyols with isocyanates and control the density, hardness and elastic properties of the foam. Common amine catalysts include triethylenediamine (TEDA), dimethylamine (DMEA), etc.
1.3 Advantages of polyurethane foam amine catalysts
- High elasticity: Polyurethane foam amine catalysts are able to produce highly elastic foam materials and are suitable for wearable devices that require frequent bending and stretching.
- Lightweight: The foam material itself is lightweight and does not put additional burden on the user.
- Breathability: Polyurethane foam has good breathability, can effectively discharge sweat and keep the skin dry.
- Heat Insulation: Foam materials have excellent thermal insulation properties and can maintain body temperature in cold environments.
