HDPE for Rotational Molding

---

HD3840UA is a medium density polyethylene with narrow molecular weight distribution. It is suitable
for rotational molding including some injection molding applications such as technical parts and
closures. HD3840UA has UV-stabilizer which offers good impact resistance, high environmental
stress cracking resistance and has excellent surface finish. It is supplied in pellet form.

APPLICATIONS
Blow-molded containers up to 5 liters for packaging:

• Large Tanks (up to 30,000L)
  
• Silos
  
• Engineering Parts
  
• Toys
