The technical data sheet (TDS) of SAN 82TR material from LG Chem corporation, if there are differences, please refer to the official website of LG Chem.
High transparency and good gloss, providing a clean and smooth surface finish after molding, making it ideal for transparent visual structural components with uniform and stable coloring performance.
High rigidity, tensile strength, and flexural strength, preventing component deformation while offering a narrow mold shrinkage range and exceptional dimensional stability.
Resistant to daily chemicals such as grease, weak acids, and weak bases, making it less prone to stress cracking and suitable for applications in contact with personal care products and food containers.
Moderate processing flowability with a wide molding window, accommodating thin-walled and complex injection-molded parts with strong mass-production stability.
Excellent heat resistance, with a Vicat softening point reaching up to 100℃, allowing short-term resistance to higher operating temperatures.
Consistent original polymer manufacturing processes with minimal batch-to-batch physical property fluctuations, serving as an economical transparent raw material that effectively optimizes overall production costs.
Home Appliances: Water dispenser transparent windows, coffee machine accessories, air conditioner control panel transparent covers, small appliance transparent housings, and washing machine observation components.
Consumer Electronics: Small instrument transparent panels, charger housings, audio equipment transparent decorative parts, and meter transparent protective covers.
Daily Consumer Goods: Transparent storage containers, cups, cosmetic packaging shells, and small kitchen appliance transparent components.
Industrial Instruments: Inspection equipment observation windows, flow meter housings, and small instrument transparent shells.
Stationery & Toys: Transparent stationery shells, high-end transparent toy components, and decorative transparent bases.
Q1: How should the drying process be configured when processing LG Chem SAN 82TR raw material?
A: SAN materials absorb moisture easily, and insufficient drying can cause defects such as silver streaks and bubbles. It is recommended to set the drying temperature to 80–85℃ for 3–4 hours, maintaining a moisture content below 0.02% prior to injection molding.
Q2: How should one choose between SAN 82TR, transparent ABS, and PMMA?
A: SAN 82TR offers better chemical resistance than transparent ABS and is lower in cost than PMMA, though its low-temperature toughness is relatively lower. Choose SAN if chemical resistance is needed on a budget; choose transparent ABS if high impact strength is required; and opt for PMMA when seeking ultimate light transmission and high surface hardness.
Q3: Does LG Chem SAN 82TR comply with RoHS environmental standards? Can it be used for food contact?
A: The base resin complies with RoHS hazardous substance control regulations. For food-contact applications, please request the original manufacturer’s material certificate from your supplier and complete final product compliance verification in accordance with target market regulations (such as FDA or GB 4806).
Q4: Can SAN 82TR be used for extrusion molding?
A: This grade is primarily positioned for injection molding, and injection molding is the preferred recommendation. It is not recommended for high-speed extrusion of films or sheets; for extrusion applications, please select LG Chem’s dedicated extrusion-grade SAN resins.
