Can anyone tell me about the shelf life of Polypropylene or other polymer granules and what are exact storage condition requirements to extend its shelf life

There are different

There are different polypropylene products in the market, and depending on their usage, the shelf life can differ. Factors affecting its shelf life include temperature and frequency of usage. I am not sure what are the exact factors though.

According to Dow chemicals

According to Dow chemicals polypropylene glycols and polyglycol copolymers have a recommended shelf life of two years. I don't know if that is the same type of polypropylene product you were curious about.

Most material suppliers have

Most material suppliers have data generated and some provide on MSDS sheet. Normally PP has an unlimited shelf life if stored in a cool dry location. Most protect the area with automatic overhead sprinkler systems. Hope this helps when with and elastomer group we did studies out to five years and had no problems running material or loss of properties.
