Features
Handling and Health Safety
sMolten polymers could be injured skin or eye so safety glasses and appropriate gloves aresuggested to prevent possible thermal injuries. Also, appropriate ventilation is suggested in working by melt polymer. Accumulation of fines or dust particles that are in this grade is not suitable because of explosion hazard probability. So adequated filters and grounding exists at all time are recommended.
Storage
Polyethylene products (in pelletized or powder form) should not be stored in direct sunshine and/or heat radiation. Ultraviolet cause a change in the material properties. The Storage area should be dry and preferably don't exceed 50 °C. Under cool, dry, dark conditions Jam Polymers polyolefin resins are expected to maintain the original material and processing properties for at least 18 month. . JPC would not responsible about quality diminishing such as color change, bad smell or ets which caused by bad storage conditions. It is better to process PE resin within 6 months after delivery.
packaging
Jam Polymers Polyolefin resins are supplied in pellet form packed in 25kg bags. Alternative packaging modes are available for selected grades.
