    CYC quartz fiber chopped strand should be stored in its original packing in a dry and cool place with its orginal package. Best conditions are at temperatures from 15 to 35°C and humidity between 35 to 65%. To ensure safety and avoid damage to the product, the pallets should not be stacked more than three layers high, when the pallets are stacked in 2 or 3 layer, care should be taken to correctly and smoothly move the top pallet.CYC Quartz Fiber Chopped Strand
