How to Use Minor Ingredients in Slow Rebound Foam Formulation?
This article discusses the selection and use of minor ingredients in the formulation of slow rebound foam, highlighting the importance of choosing the right amines, tin catalysts, silicone oils, and pigments to ensure high-quality product outcomes.
What is the Impact of Polyurethane Raw Materials on the Production of Flexible PU Foam?
This article explores the impact of various polyurethane raw materials—such as polyether, foaming agents, TDI, catalysts, stabilizers, temperature, humidity, and atmospheric pressure—on the properties and production of flexible foam.
What is Isocyanate?
Isocyanates, crucial in polyurethane production, include TDI variants (2,4-TDI, 2,6-TDI). TDI-100 suits castable polyurethane, T-80 is widely used, and T-65 is for high-rebound foams. Reactivity varies due to molecular structures. TDI is a transparent liquid with a coloration tendency, distinctive odor, and solidification point influenced by composition.
