The shelf life of rubber products varies greatly due to material type, storage conditions and usage scenarios, usually ranging from 3-5 years to more than 20 years. It can be divided into the following situations:
Core Influencing Factors
Material type:
Natural rubber (NR): The shelf life of general products is 3-5 years (such as condoms), but if the raw materials are not processed and stored, they can only be kept for 2-6 months.
Synthetic rubber (such as styrene-butadiene rubber SBR, nitrile rubber NBR): The shelf life is usually 3-5 years.
Special rubber (such as fluororubber FKM, silicone rubber): The shelf life can reach more than 20 years.
Product use:
Tire: The shelf life is generally 6 years, and the performance will drop significantly after exceeding it.
Industrial rubber parts (such as seals): Depending on the material, the shelf life ranges from 5 years (such as EPDM) to 20 years.
