Masterbatch for Injection & Blow Moulding

Moulders need consistent color shot after shot and cycle times that don't creep. Our white, color and filler grades disperse cleanly at short residence times, and CaCO₃ compounds help parts cool faster in the mould.

  • Caps & closures
  • Crates & rigid containers
  • Blow-moulded bottles
  • Household plastics
  • Housewares

What We Solve

The problems our grades are built for.

  • 01

    Shade consistency

    Custom colors are spectrophotometer verified to Delta-E < 0.5 against your standard.

  • 02

    Heat history

    Pigment systems are chosen for heat stability from 240°C up to 300°C.

  • 03

    Cycle time

    CaCO₃ at 10% – 35% raises thermal conductivity and accelerates mould cooling.

  • 04

    Opacity in thin walls

    MB-W70-PE at 1.0% – 2.5% gives full whiteness in caps, closures and crates.

Recommended Grades & Dosage

What to run, and how much.

Let-down and addition levels are quoted from the grade TDS. Your final dosage depends on gauge, wall thickness and target properties; the let-down ratio calculator works out masterbatch and resin quantities for a batch.

  • MB-W70-PE

    70% Rutile White

    Injection moulded parts (caps, closures, crates)

    1.0% – 2.5%

    —

  • CP-CA80-PE

    80% Calcium Compound

    Injection moulding / housewares

    10% – 35%

    Accelerates mould cycle cooling

  • MB-CLR-CUSTOM

    Custom RAL / Pantone

    Closures, containers & household colors

    To brief

    Universal / PE / PP carriers

Processing notes

  • MB-W70-PE is compatible with LDPE, LLDPE, HDPE and PP copolymers.
  • Share part drawings or a reference part and we match color, opacity and carrier together.

FAQ

Questions about masterbatch for moulding.

  • Which masterbatch suits injection molding of caps and closures?

    For white parts, MB-W70-PE at 1.0% – 2.5% gives full whiteness in caps, closures and crates, and is compatible with LDPE, LLDPE, HDPE and PP copolymers. For colored parts, custom color masterbatch on universal, PE or PP carriers is verified by spectrophotometer to Delta-E < 0.5 against your standard.

  • Which masterbatch is used for blow moulded HDPE bottles?

    Custom color masterbatch matched to your shade, and MB-W70-PE for white HDPE containers.

  • Does CaCO₃ filler help moulding cycle times?

    Yes. Calcium carbonate raises thermal conductivity, so filled parts cool faster in the mould. CP-CA80-PE is used at 10% – 35% in injection moulding and housewares.

  • Will the color hold up to my processing temperature?

    Pigment systems are chosen for heat stability from 240°C up to 300°C. Share part drawings or a reference part and we match color, opacity and carrier together.
