What is the Standard Formulation for Flexible Polyurethane Foam?

The production formula for polyurethane foam refers to listing all raw material components—names and proportions—required for manufacturing.

The industry-standard formulation format is:

Standard Flexible Polyurethane Foam Formulation

①Industry notation: Parts per hundred parts of polyol (pphp).
②National standard unit: Relative mass fraction (denoted as "ω", expressed as "%").

Formula Variables vs. Foam Physical Properties
Remark: Low permanent deformation indicates superior performance.

Key Highlight: Thermodynamic theory in physical chemistry states that positive catalysts reduce reaction activation energy.

Temperature can change the activation energy of the reactant system and even alter the reaction direction.
