1. Product Introduction
N-Pentane
CAS NO. 109-66-0
Chemical formula C5H12
N-Pentane, a highly flammable alicyclic hydrocarbon. It has three structural isomers, n-pentane isomer, isopentane (methylbutane) and neopentane (dimethylpropane).
Pentane blends is mixed by n-pentane and iso-pentane by certain ratio, mainly used as blowing/expandable agent, for EPS foaming, etc.
Pentane 80/20 is a blend of 80% n-pentane and 20% iso-pentane.
Pentane 60/40 is a blend of 60% n-pentane and 40% iso-pentane.
Pentane 50/50 is a blend of 50% n-pentane and 50% iso-pentane.
Customer-tailored grade is available.
