EX3 is a pipe grade resin which is manufactured by suspension polymerization of ethylene monomer. 
EX3 is a bi-model high density polyethylene with 1-Butene as co-monomer.
Characteristic and Properties:
• Tough and rigid pipe resin.
Main Applications:
• Pressure pipes, e.g. drinking-water, and gas pipes, waste pipes and sewer pipes, their fittings and also sheets
(UV stabilization and pigments during processing)
Additives:
• Antioxidant/Process
stabilizer:
• Lubricant (processing aid) /acid scavenger

polymers could be injured skin or eye so safety glasses and appropriate gloves
are suggested to prevent possible thermal injuries. Also, appropriate
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 .
dust particles that are in this grade is not suitable because of explosion
hazard probability.
handling and Health Safety molten ventilation is suggested in working by melt polymer.
