PP Masterbatch

What Is PP Masterbatch?

PP Masterbatch is a concentrate — pigment or functional additive dispersed in a Polypropylene carrier resin — used to color or modify PP parts during processing. Allzone supplies Masterbatch on PP carrier across the additive and color families listed below, matched to your grade and processing method.

For the engineering explanation of what a Masterbatch is and how it works, see Color Masterbatch Explained. For choosing a specific color grade, see the Wave 6 color-name decision guides. For product-level color landings on any carrier, see Wave 7.

Compatible Masterbatch Families on PP Carrier

Allzone supplies the following families on a PP carrier — the specific product page for each family owns the shade, pigment index, and regulatory detail:

• Color Masterbatch — see the Color Product Vertical (Wave 7) for L1 landings by color; the Color-Name Decision Guides (Wave 6) for grade selection.
• White Masterbatch — see the White Masterbatch pages (Wave 4) for TiO₂-based opacity grades.
• Black Masterbatch — see the Black Masterbatch landing (Wave 7).
• Desiccant Masterbatch — see the Desiccant Masterbatch pages (Wave 4) for moisture-scavenging use on recycled or hygroscopic PP.
• Additive Masterbatch — UV stabilizer, antioxidant, antistatic, slip/anti-block, processing aid — quoted on request against your target application.

This page does not re-explain those families; it confirms which are available on a PP carrier and links to the owning product page.

Typical Processing Methods for PP

Injection Molding, Extrusion, Film (BOPP/CPP), Raffia, Blow Molding, Non-woven Fiber.

Recommended processing conditions match the host polymer; the pigment or additive heat-stability ceiling is disclosed on the TDS/COA.

Grade & Concentration Notes

• Carrier–host compatibility is a hard requirement, not a preference. See Carrier Selection (CT-ART-002). A mismatched carrier resin causes gels, dispersion loss, or unexpected mechanical drops.
• Melt-flow matching. Match Masterbatch carrier MFI within roughly one order of magnitude of your host PP grade to avoid streaking, gel formation, or dispersion loss.
• Standard concentrations vary by family (Color 20–50 %, White 50–80 % TiO₂, Additive family-dependent). Specify let-down ratio and target performance rather than pigment percentage alone.
• Custom concentration and custom grades available on request — specify your target let-down ratio, host-polymer grade, and end-use requirement on the RFQ.

Homopolymer vs copolymer PP behave differently under low-temperature impact; declare which grade you run on the RFQ.

Typical Applications

Rigid packaging, caps and closures, PP crates and pallets, raffia bags (FIBC/woven sacks), non-woven hygiene fabrics, automotive interiors, appliance housings.

Application-specific requirements (food contact, medical, toy, outdoor exposure, chemical resistance) are declared on the RFQ and dictate which pigment index, additive package, and carrier grade are selected.

What to Send on Your RFQ

For a usable PP Masterbatch quotation, provide:

1. Host polymer grade — PP type (declare grade family, e.g. homopolymer/copolymer, HDPE bottle vs pipe, mLLDPE vs Ziegler, GPPS vs HIPS) and MFI or IV.
2. Processing method — which of the above processes runs on your line.
3. Masterbatch family — Color / White / Black / Desiccant / Additive (or combination).
4. Target performance — shade + ΔE tolerance, opacity target, additive dose, or functional spec.
5. Regulatory frame — food contact (FDA, EU 10/2011), toy (EN 71-3), medical, potable water, or none.
6. Volume and MOQ — kg per order, annual estimate, sample requirement.

So What Should the Buyer Investigate Next?

Before issuing the PO, verify: (a) the Masterbatch carrier is compatible with your specific PP grade — not just the polymer family, (b) the MFI or IV window matches your processing window, and (c) the pigment index or additive package on the TDS matches your regulatory frame and end-use exposure. If any of these three is missing, the risk sits on your production floor — not on the supplier's.
