Biography

My name is Peyman Ezzati. I was born in 1980, Saqqez, Kurdistan, Iran. I started my academic career in polymer engineering as one of the top selected candidates at Amirkabir University of Technology (AUT). In 2005, I was accepted as a MS student at the Iran Polymer and Petrochemical Institute (IPPI). I successfully received my admission in 2008 from IPPI to start my PhD.

My Experience in 15 Years:
•Coach for Rubber and Elastomer Industries by Training and Consulting
•R&D Manager (Technology transfer, technology development, process development, industrialization)
•Innovation Manager
•CEO (Managing Director) and member of the board of polymer production companies
•Factory Manager
•Start-Up founder

In 2021, I was selected as a foreign talent by the Chinese government and came to this country. 

Abstract

In this study rheometrical behavior of NBR compound in closed cell flexible elastomeric foam (FEF) was investigated. In manufacturing of NBR, FEF curing and blowing affected on production which shown in rheometrical parameters. Rheometer diagram studies of different FEF foamed formulation based on NBR showed curing and blowing phenomenon simultaneously. These parameters were such as scorch time, curing rate index (CRI) minimum torque (ML) and maximum torque (MH). Scorch time showed that process must be design in the way that blowing should start at first and after blowing curing must occur. Blown cells whit N2 gas contains must cure simultaneously so that it needs ultrafast curing acceleration and CRI in highest level. MH and ML parameters, must be check for each and individual product. MH, ML, MH-ML despite 300% modulus, viscosity, chain length duration (CLD) respectively.
