What is Lustran ABS 348?

Lustran ABS 348 is an engineering plastic specially developed by INEOS Styrolution for the medical and precision injection molding fields. As an injection-grade, food-contact grade and medical-grade ABS material, it combines mechanical strength, surface gloss and processing stability, and is suitable for application scenarios with high requirements for both safety and appearance, such as surgical instruments, diagnostic equipment, laboratory components and food-related parts.

1. Material Properties

Injection Grade: Optimized for injection molding processes, this material exhibits excellent flowability and shrinkage control, enabling the formation of fine appearances and uniform structures in complex molds. Its high dimensional stability significantly reduces the risk of warpage and deformation.

Food Contact Grade: Through formulation and purity control, ABS lustran 348 meets the migration and chemical stability requirements of food contact materials, making it suitable for food packaging and processing equipment components.

Medical Grade: Meets the physical and chemical stability standards for medical device applications, exhibits excellent biocompatibility, and can withstand routine cleaning, alcohol wiping, and short-term high-temperature sterilization without affecting mechanical properties.

2. Material properties

Lustran ABS 348 takes into account mechanical, appearance and craftsmanship performance. Its three key characteristics are as follows:

High gloss

  ・The surface is smooth and fine, presenting a lustrous texture. For medical equipment or consumer electronics casings with strict appearance requirements, this visual effect not only enhances brand image but also reduces the need for additional painting and polishing.

Hoge treksterkte

  ・The material has a stable mechanical response under tensile load, can maintain long-term deformation stability and structural integrity, and is suitable for load-bearing parts and precision assembly structures.

Impact improvement

  ・The formula has been designed with enhanced impact toughness, which can maintain excellent fracture ductility at low temperatures or under impact, preventing brittle cracking and failure.

3. Electrical and thermal performance

Insulation and electrical strength

  ・With high volume resistivity and good dielectric strength, it can provide reliable electrical safety protection in applications such as live medical instruments and electronic enclosures.

Thermische stabiliteit

  ・The material can maintain its shape stability at around 100°C, with a high heat distortion temperature, making it suitable for use in high-temperature disinfection or continuous working environments.

Flame retardant grade

  ・UL94 grade is HB, meeting the fire protection requirements for the enclosures of general electronic and medical equipment. If higher flame retardant performance is required, the V series modified materials under Benling can be selected.

4. Processing and technology compatibility

Excellent injection molding performance: Compatible with standard ABS molding Windows, with a balanced melt index and flow rate, it can fully fill complex molds.

Mold design suggestions: The high gloss characteristic requires a high polishing grade on the mold surface. It is recommended to use mirror finish to ensure consistency in appearance.

Post-processing compatibility: Suitable for secondary processing such as screen printing, hot pressing, laser engraving, etc., and has strong resistance to common disinfectant solvents.

5. Typical Application Areas

Surgical Instruments and Medical Device Housings: Combining mechanical strength and disinfection resistance.

Laboratory Instruments and Diagnostic Equipment: High dimensional stability, maintaining assembly accuracy.

Food processing and packaging components: Meets food contact safety requirements and has high chemical inertness.

Consumer electronics housings and control panels: High-gloss surface combined with impact resistance and durable appearance.

7. Product selection suggestions

If you pay attention to the comprehensive balance of appearance texture, structural strength and medical safety, Lustran ABS 348 is the ideal material choice.

If the project requires a higher heat resistance or stronger flame retardancy grade, the Terluran series of Benzenling or the solution of blending with PC can be considered.

For low-temperature impact or special sterilization environments, it can be tested and selected in combination with modified ABS or MABS materials.
