Features & Benefits

Performance Properties

Engineering Resin B copolymer resins are a new family of polycarbonate copolymers that
can provide improved chemical resistance. These resins are based on unique copolymer
building block blends offering a combination of:

• Improved Chemical Resistance: Improved chemical resistance to a range of chemical disinfectants
• Impact Retention: Retention of ductility upon exposure to chemicals.
• Processability: Potentfoir ahilgh productivity molding and cycle time reduction.
• Flame Retardancy: V0 rating up to1.5 mm thickness
• Esthetics: Consistent opaque color and appearance

Product Highlights

Improved Chemical Resistance Materials for Medical Enclosures and Housings

With patient safety at the forefront, the healthcare industry is mobilizing to address the concerns of increasing patient infections associated with medical care, known as hospital-acquired infections (HAIs). To help meet this challenge, medical equipment and high touch surfaces in patient care settings are repeatedly wiped down with increasingly aggressive chemical disinfectants.

Chemical Resistance Data - Environmental Stress Cracking (ESC) Performance

Compared to traditional PC, ABS, PBT and co-polyester resins and blends which are potentially incompatible with highly aggressive disinfectants such as quaternary ammonium compounds the new Engineering Resin B resins can help prevent stress cracking and mitigate crack propagation.

SABIC’s Engineering Resin B resins leverage unique copolymer technology to provide improved chemical resistance for healthcare devices and equipment, compared to existing materials used such as PC/ABS, PC/PBT, or co-polyester resins and blends.

Note

• ⁴² Injection Molding parameters are only mentioned as general guidelines. These may not apply or may need adjustment in specific situations such as low shot sizes, large part molding, thin wall molding and gas-assist molding.
• ⁴⁹ The information stated on Technical Datasheets should be used as indicative only for material selection purposes and not be utilized as specification or used for part or tool design.
• ⁵⁹ UL Ratings shown on the technical datasheet might not cover the full range of thicknesses and colors. For details, please see the UL Yellow Card.
• ¹² Measurements made from laboratory test coupon. Actual shrinkage may vary outside of range due to differences in processing conditions, equipment, part geometry and tool design. It is recommended that mold shrinkage studies be performed with surrogate or legacy tooling prior to cutting tools for new molded article
• ²⁹ UL Ratings shown on the technical datasheet might not cover the full range of thicknesses and colors. For details, please see the UL Yellow Card.
