HMC is pleased to announce an exciting new PP RACO grade: Moplen RP6068

The One Grade Solution

Moplen RP6068 delivers high impact resistance for extrusion blow molding (EBM) and was designed to deliver excellent clarity, softness, aesthetics and a good balance of stiffness and impact resistance; particularly for large size containers and bottles.


Large size containers require a high level of impact resistance, but typical PP RACO grades usually offer insufficient toughness, requiring molders to boost that capability by blending the PP with an impact modifier.

Now, with Moplen RP6068 it is possible to eliminate the blending of impact modifier. Instead, molders simply use RP6068 at 100%, thus reducing production costs and improving consistency and product quality.

TYPICAL APPLICATIONS
  • High clarity rigid packaging
  • Large containers requiring good drop impact resistance and providing cost savings due to the elimination of an impact modifier
  • Soft touch or squeezable containers
  • Possible LDPE replacement offering improved barrier and downgauging for tube containers and blown film applications
  • High clarity extrusion sheet and thermoformed parts

KEY FEATURES
  • Broad processing window
    - High melt strength provides good parison control
    - Energy Saving (lower processing temperature compared to standard random copolymer)
    - Solidifies fast, reducing cycle times
  • Excellent aesthetic appearance
    - Superior clarity and gloss
    - Soft touch
  • Outstanding impact resistance
    - Excellent Izod & bi axial impact strength
    - Good balance of stiffness and impact resistance

PROPERTY COMPARISON
We compare the key properties between Moplen RP6068 and the existing grade (Moplen RP242 G) blended with impact modifier. Moplen RP 6068 offers similar Izod impact strength to Moplen RP242 G blended with 10% impact modifier. In particular, its optical properties are better than RP242 G for all formulas.
