AS Chi Mei Taiwan PN‑107L125
Product Introduction AS Chi Mei Taiwan PN‑107L125 resin is a high‑flow, high‑transparency acrylonitrile‑styrene copolymer (AS/SAN). It combines good rigidity and excellent processability, and complies with relevant food‑contact regulatory certifications.
Main Applications
Food Packaging & Containers: Food containers, sealing cans, tableware and kitchen appliances. High transparency plus compliance with EU 10/2011 and Chinese GB4806 standards make it ideal for these scenarios.
Daily‑use Consumer Goods & Cosmetic Packaging: Cosmetic cases & cosmetic packaging, toothbrush handles, pen barrels, refrigerator fruit‑vegetable boxes and TV bases.
Electronic & Electrical Components: Electrical sockets, housings, instrument casings, battery boxes, storage‑battery enclosures and junction boxes. Reliable electrical insulation and mechanical strength meet component performance requirements.
Automotive Industry: Automotive parts including head‑lamp housings, rear‑view mirror housings and instrument panels.
Industrial & Other Articles: Oil‑resistant mechanical parts, tractor fuel tanks, packaging containers and stationery.

Injection‑Molding Parameters
| Process Parameter | Reference Range | Remarks & Instructions |
|---|---|---|
| Drying Treatment | 75‑80°C, 3‑4 hours | AS resin is hygroscopic. Sufficient drying is required (moisture content below 0.1% recommended), otherwise silver streaks and bubbles may occur on finished‑part surfaces. |
| Barrel Temperature | Feed zone:160‑180℃ | Compression zone:180‑200℃ | Nozzle:180‑210℃ | Use lower melt temperature for thick‑wall products. Prevent material degradation; avoid long‑term residence of molten material inside high‑temperature barrel. |
| Mold Temperature | 40‑60℃ | For high‑precision molded parts within this range. Mold temperature directly affects appearance, shrinkage and warpage of finished products. |
| Injection Pressure | 50‑70 kg/cm² | Adjust according to flow length and product structure. |
| Holding Pressure | 40‑60 kg/cm² | Approx.30%‑60% of injection pressure. Optimize according to wall thickness and product structure to reduce internal stress and shrinkage. |
| Back Pressure | 5‑15 kg/cm² | Proper back‑pressure ensures uniform plasticization and degassing. |
| Injection Speed | High‑speed injection recommended | Beneficial for good surface gloss, color performance and minimizing weld‑lines. |
