What Is The Typical Shelf Life Of Polyurethane Rollers?

The shelf life of polyurethane rollers is usually 1-2 years. High-quality products can extend to over 2 years under ideal storage conditions.

1. Typical Shelf Life Range

- Ordinary polyurethane rollers: 1-2 years (unused and stored under suitable conditions)

- High-performance/high-quality rollers: Over 2 years (requires advanced processes and strict storage)

2. Key Influencing Factors

• Storage Environment: Temperature around 25℃, humidity below 60%, protected from light and chemical corrosion

• Material Quality: High-purity raw materials can delay aging

• Manufacturing Process: Cast polyurethane is generally more resistant to storage than compounded polyurethane.

3. Abnormal Conditions that Shorten Shelf Life

- High temperature (>35℃) or high humidity (>70%) environments may shorten shelf life to several months.

- Contact with oils, strong acids, strong alkalis, and other chemicals will directly lead to performance degradation.
