How to Formulate the Operating Recipe for Flexible Polyurethane Foam?

The operating recipe is a deep integration of the operator, formulation, and machinery.

1.Foaming production process

Preparation of each raw material → Temperature control of materials → Calibration and verification of material flow rates → Lab test → Determination of standard formulation, base formulation, and production formulation → Formulation of operating recipe based on flow rate measurements

Example of operating recipe

2. What Is the Role of Lab Testing?

① Verification of formulation design

② Inspection of raw materials and additives

③ Verification of environmental conditions
