Material Selection for Transparent Electronic Housings: Key Data of MABS TR558A

Selecting a material for transparent electronic housings requires balancing optical, mechanical, and processing properties. The technical data of  LG Chem's MABS TR558A provides clear benchmarks.

Optical Properties: 90% Light Transmittance and 1.8% Haze (ASTM D1003). This indicates high clarity suitable for applications requiring visual access or aesthetic appeal.

Mechanical Properties: Izod Impact Strength is 125 J/m at 23°C, offering better toughness than many transparent polystyrenes. Tensile Strength is 52 MPa, and Flexural Modulus is 2550 MPa.

Processing Parameters: A Melt Flow Rate of 25 g/10min (220°C/10kg) classifies it as a high-flow material, facilitating filling of complex molds and efficient production. Drying is recommended at 80-90°C, with a melt temperature range of 200-230°C.

Compliance: The material carries a UL94 HB rating and an RTI Elec of 50°C, meeting basic safety requirements for electronic enclosures.

In summary, MABS TR558A presents a viable option when the design calls for better clarity than standard ABS, good impact resistance, and easy processability without the cost and processing challenges of PC.
