HDPE made via Hostalen Process

HD-7255 is an injection molding resin which is manufactured by the suspension polymerization of ethylene monomer. This grade apply in thick walled containers making which are used for liquid transportation. this grade is applicable in designing the vessels for high stressed transportation.

Handellling 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.


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. It is advisable to process PE resin within 6 months after delivery . 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.


Jam Polymers Polyolefin resins are supplied in pllet form packed in 25kg bags. Alternative packaging modes are avalable for selected grades.
