Usage：
Pentane blends is mixed by npentane and isopentane by certain ratio, mainly used as blowing/expandable agent, for EPS foaming, etc.
Pentane 80/20 is a blend of 80% npentane and 20% iso pentane.
Pentane 60/40 is a blend of 60% npentane and 40% isopentane.
Pentane 50/50 is a blend of 50% npentane and 50% isopentane.
Customer-taliored grade is avaliable.
