Ultraplen® PP MF40 — mineral-filled polypropylene with 40% talc
Description
Ultraplen® PPMF40 is a mineral-filled polypropylene with 40 % talc from Material Wizard. An injection molding compound on a homopolymer PP matrix with 40 % fine-particle talc (D50 ~3–5 µm) and an optimized compatibilizer package. Developed as a cost-effective technical alternative to glass-filled PP in applications where the critical requirements are a smooth glossy surface with no visible fiber, isotropic shrinkage, increased heat resistance and high impact strength at moderate stiffness.
Why mineral rather than glass — the technical logic
- Isotropic shrinkage (~0.9–1.2 % in all directions) versus the strong anisotropy of GF compounds — critical for flat and large-area parts (instrument panels, trim covers).
- Clean surface without white streaks — well suited for cosmetic parts without subsequent painting / texturing.
- Better impact balance at equal stiffness — talc acts as a crystallization nucleating agent, increasing impact strength.
- Lower abrasive load on the screw and mold compared with GF — extends tooling life.
- Cost 15–25 % lower than a comparable GF-filled PP.
Advantages
- Increased stiffness with a modulus of 3.5–4.5 GPa while retaining the impact strength of a PP homopolymer
- Isotropic shrinkage — minimal warpage in flat and large parts
- Smooth glossy surface of the finished part with no visible flow lines
- Good heat resistance for parts operating briefly at 100–120 °C
- Low wear of tooling and screw — extends mold life by 2–3 times vs a GF compound
- Can be colored in any shades without the dark tint of fiber showing through
- Low water absorption — dimensional stability in any climate
- EU 10/2011 compliance for food-contact applications (on request)
Limitations — honestly
- Stiffness lower than Ultraplen® 530 (GF30) — 4 GPa modulus vs 7 GPa. For loaded structural parts choose a GF compound.
- HDT/A (1.8 MPa) ~75 °C — parts operating under load above 80 °C require GF compounds or PA
- Brittleness at sub-zero temperatures — outdoor applications in cold climates require an EPDM impact modifier
- UV-unstable in the base formulation — a HALS package is added for outdoor use
- Base grade is HB — for FR applications switch to Ultraplen® 600 (V-2)
- Talc sedimentation during prolonged melt residence — processing regimes must maintain constant mixing
Target applications
Home appliances: vacuum cleaner housings, bases and lids of kitchen appliances, fan housings, food storage containers (food-contact package on request), refrigerator parts.
Automotive (interior): instrument panel trim, door trim, center consoles, sill trim, trunk compartment elements, holders and guides.
Industrial packaging: technical containers, pallets, storage crates, IBC lids with increased stiffness.
Electrical engineering: junction box housings (without FR requirements), cable organizers, mounting chassis for low-voltage systems.
Furniture industry: structural elements of office furniture, drawer slide guides, wall-mounting bases.
