★High workshop humidity does not automatically mean a flexible PU foam formulation should be changed. This video explains how humidity affects foaming stability when extra moisture enters the formulation system through raw materials, fillers, color pastes, or additives. It focuses on judging actual moisture deviation, not simply reacting to the humidity meter reading. ★Timestamps 00:00 Air humidity vs actual moisture in foam production 00:27 How moisture can enter the formulation system 00:58 Why water changes the PU foam reaction 01:26 Foam structure and physical property fluctuations 02:05 Why TDI should not be adjusted too quickly 02:25 What to check before judging humidity effects ★Temperature, Humidity & Seasonal Effects in Foam Production| EP05 ★For foam production lines or machine projects: Email: [email protected] Website: https://www.sabtechmachine.com ★Related playlist: Defects, Failures & Risk Control - • Defects, Failures & Risk Control Raw Materials & Additives - • Raw Materials & Additives #FlexiblePUFoam #PUFoamProduction #FoamFormulation #HumidityControl #Sabtechfoammachine
