Propylene
Propylene is one of the most important basic chemicals in the petrochemical industry. It's like a building block that companies use to make many everyday products, from plastic containers to car parts. Think of it as a raw ingredient that gets transformed into various useful materials. It's similar to other basic chemicals like ethylene, and together they're often called 'olefins' in the industry. When you see this term in resumes, it usually means the person has experience working with this chemical in production plants or managing its manufacturing process.
