PP-SABIC PP 570P
PP-SABIC PP 570P è un omopolimero di polipropilene appositamente sviluppato da SABIC per articoli stampati a iniezione rigidi di uso generale che richiedono processabilità costante, buone proprietà meccaniche ed elevata lucentezza. Con un indice di fluidità stabile di 8 g/10 min e un elevato modulo a flessione (1630 MPa), è altamente specificato per casalinghi durevoli, tappi, chiusure e giocattoli. In Jucheng Precision, produttore certificato ISO 9001 e IATF 16949, sfruttiamo le nostre oltre 35 presse di stampaggio avanzate (50-650T) e attrezzature CNC a 5 assi interne per controllare il tasso di ritiro dell'1,2%-2,5%. Forniamo analisi DFM gratuita entro 24 ore per ottimizzare il bilancio termico, consegnando parti impeccabili e ad alta lucentezza verificate tramite ispezione CMM Zeiss.
SABIC PP 570P Structural and Rigid Processing Profile
SABIC® PP 570P is a highly reliable homopolymer resin designed to deliver high rigidity and aesthetic gloss for domestic and consumer articles:
| Attributo del materiale | SABIC 570P Specification | Vantaggio ingegneristico per parti stampate |
|---|---|---|
| Stiffness-to-Weight | Flexural Modulus 1630 MPa | Provides superior load-bearing strength and rigidity at a low density of 0.905 g/cm³, allowing for lightweighting of thick-walled containers. |
| Cosmetic Gloss | Inherent High-Gloss Homopolymer | Ensures a premium, brilliant surface gloss directly from polished tool cavities, reducing the need for post-molding finishing or painting. |
| Food Safety | FDA Food Contact Compliant | Fully certified for safe and non-toxic direct contact with food and household consumables, ensuring zero taste or odor transfer. |
Molding Configuration Adaptability for SABIC PP 570P
With a Melt Flow Rate of 8 g/10 min, SABIC PP 570P flows smoothly and packs tightly under standard molding setups:
| Categoria di processo | Suitability & Practical Application |
|---|---|
| Standard Rigid Molding | Excellent. Highly optimized for thick-walled housewares, storage boxes, furniture structural parts, and heavy-duty kitchen containers. |
| Cap & Closure Molding | High. Its robust stiffness and low shrinkage anisotropy support the fabrication of rigid caps, closures, and threaded bottle covers. |
| Stampaggio con Inserti | Good. Allows integration of metallic brackets or structural pins directly inside rigid houseware structures. |
PP-SABIC PP 570P Tooling & Injection Processing Guide
To prevent warpage and optimize the high-gloss surface of SABIC PP 570P, Jucheng’s engineering team implements precise process profiling:
- Optimizing Surface Gloss (High Mirror Polishing): To fully exploit PP 570P’s high-gloss potential, Jucheng’s tooling division uses hardened tool steel (such as S136) polished to a high mirror finish. We maintain high mold temperatures (up to 40°C–65°C) for visual parts, ensuring the molten resin replicates the mold surface perfectly.
- Warpage Control & Shrinkage: This grade exhibits a mold shrinkage of 1.2% to 2.5% depending on wall thickness. Our engineers implement highly uniform wall thicknesses during DFM review and use our 5-axis CNCs to machine balanced cooling channels to prevent uneven cooling and thermal warping.
- Processing Temperatures: Barrel temperatures are tightly kept between 200°C and 250°C (392°F to 482°F). Adequate pack pressure and slow injection speeds are applied to prevent sink marks on structural rib joints.
- Pre-essiccazione: While not strictly necessary due to PP’s hydrophobic nature, we pre-dry at 80°C (176°F) for 1–2 hours if the raw material is exposed to humid storage, preventing surface splay.
Key Application Fields for PP-SABIC PP 570P
- Rigid Housewares: Heavy-duty storage organizers, high-gloss kitchenware, plastic buckets, cups, and food-safe plates.
- Packaging Closures: Rigid threaded caps, flip-top lids, pharmaceutical closures, and general consumer container lids.
- Toys & Furniture Accessories: Structurally rigid toy assemblies, high-gloss children’s furniture components, and high-impact plastic drawers.
