Shelf life and storage conditions
Shelf life of the product for flakes is 6 months.
Due to the thermoplastic nature of the product, to prevent flakes remassing and fusing together, it is recommended to store in a temperature controlled area <25°C and avoid direct sunlight.
Do not stack pallets and prevent prolonged storage.
Remassing does not affect the specification of the product, and if it can be readily broken this is not a basis for rejection.
