HDPE made via Spherilene Process
52511 is a HDPE copolymer injection molding grade for applications
requiring a good balance between physical properties and
flowability, like housewares and toys.

Handling and Health Safety
Molten 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 pelletised 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
ressponsible 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
avalable for selected grades
