Features
Handling and Health Safety
sMolten polymers could be injured skin or eye so safety glasses and appropriate gloves are
suggested 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
