PP-SABIC PP 570P
Le PP-SABIC PP 570P est un polypropylène homopolymère spécialement développé par SABIC pour des articles moulés par injection rigides à usage général nécessitant une processabilité constante, de bonnes propriétés mécaniques et un brillant élevé. Avec un indice de fluidité stable de 8 g/10 min et un module de flexion élevé (1630 MPa), il est spécifié pour les articles ménagers durables, les bouchons, les fermetures et les jouets. Chez Jucheng Precision, un fabricant certifié ISO 9001 et IATF 16949, nous tirons parti de nos plus de 35 presses de moulage avancées (50-650T) et de notre outillage CNC 5 axes interne pour contrôler son taux de retrait de 1,2 % à 2,5 %. Nous fournissons une analyse DFM gratuite sous 24 heures pour optimiser l'équilibre thermique, livrant des pièces impeccables à haute brillance vérifiées par inspection 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:
| Material Attribute | SABIC 570P Specification | Avantage technique pour les pièces moulées |
|---|---|---|
| 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. |
| Sécurité alimentaire | 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:
| Catégorie de processus | 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. |
| Moulage par insertion | 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.
- Pré-séchage : 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.
