Trinseo STYRON A-tech 1175 Structural and Crack Resistance Profile
STYRON™ A-tech 1175 is an advanced technology high impact polystyrene (HIPS) engineered to combine extreme toughness with chemical resistance against oils and foodstuffs:
| 性能参数 | STYRON A-tech 1175 Specification | 成形＆組立の利点 |
|---|---|---|
| Environmental Stress Crack Resistance (ESCR) | Exceptional ESCR to fats & hydrocarbons | Prevents environmental stress cracking caused by exposure to food oils, chemical detergents, and hydrocarbon agents in refrigeration environments. |
| 構造剛性 | Tensile Modulus 1650 MPa | Provides robust, load-bearing mechanical stiffness, enabling wall-thickness down-gauging in large home appliance shells. |
| Impact Resistance | Charpy Notched Impact 11 kJ/m² | Rubber-modified polybutadiene domains provide extreme impact toughness, preventing brittle cracking under physical impact. |
Process Compatibility for STYRON A-tech 1175
With a Melt Flow Index of 2.8 g/10 min, STYRON A-tech 1175 provides great melt strength and supports robust structural runs:
| Molding Configuration | 成形適合性と実施詳細 |
|---|---|
| High-Impact Rigid Molding | Excellent. Highly optimized for thick-walled appliance liners, structural refrigerator inner components, and durable home appliance brackets. |
| Deep-Draw Thin-Wall Components | High. Its exceptional melt strength prevents wall tearing during progressive cavity packing, facilitating uniform wall thickness. |
| インサート＆オーバーモールディング | Good. Rigid metal hinges or electrical housings can be easily insert-molded without cracking the surrounding HIPS substrate. |
PS-Trinseo STYRON A-tech 1175 Tooling & Flow Line Prevention Guide
STYRON A-tech 1175 is an amorphous HIPS with a low mold shrinkage rate, but managing weld-line weakness and internal stresses is key to preserving its ESCR properties:
- Optimizing Weld Line Integrity: In refrigeration and food contact parts, weld lines (where melt flows meet) are highly vulnerable to stress cracking. Jucheng’s tooling division conducts extensive Moldflow simulations during our free 24-hour DFM phase to position gates strategically, shifting weld lines away from high-stress areas.
- Mold Temperature Control (Surface Gloss): We maintain elevated mold temperatures at 40°C–65°C (104°F to 149°F) using pressurized temperature controllers. High mold temperatures maximize surface gloss, reduce flow marks, and minimize molded-in residual stresses.
- 科学的な射出プロファイリング： Processing melt temperatures are kept between 200°C and 250°C (392°F to 482°F). Slow to moderate injection speeds combined with progressive packing pressures are applied to avoid rubber-phase shear degradation.
- 予測可能な低収縮率： STYRON A-tech 1175 exhibits a low, uniform shrinkage rate of 0.4% to 0.8%. This enables our 5-axis CNC machining center to cut precise, tight-tolerance mold cavities.
Key Application Fields for PS-Trinseo STYRON A-tech 1175
- Home Appliances & Refrigeration: Large refrigerator door liners, food-contact vegetable crisper drawers, air conditioner covers, vacuum cleaner shells, and washing machine trims.
- 家庭用電化製品： TV protective back covers, printer paper trays, computer monitor housings, and structural electronic enclosures.
- Food-Safe Industrial Packaging: Thick-walled reusable food-contact containers, heavy-duty stackable grocery trays, and pharmaceutical secondary packaging.
