Storage and Handling
PP resin should be stored to prevent a direct exposure to sunlight and/or heat. The storage area should also be dry and preferably don’t exceed 50°C. Factory would not give warranty to bad storage conditions which may lead to quality deterioration such as color change, bad smell and inadequate product performance. It is advisable to process PP resin within 6 months after delivery.
