Resins and Compounds for Water Management Applications

SABIC’S specialty resins and compounds offer the water management industry design flexibility to produce products with longer lives and higher quality. Our materials are excellent candidates to replace metal and can provide weight reduction, corrosion resistance, high strength and stiffness or inherent lubricity depending on the application’s requirements.

• Hydrolytic stability
• Low water absorption
• Dimensional accuracy

In addition to mechanical requirements, applications for the water management industry need certification for potable water compliance according to national standards. SABIC has developed a dedicated potable water certified portfolio to help our customers accelerate their application development time to market.

SABIC Offerings Certified for Water Management Applications:

For applications that do not require potable water certification, SABIC’s Specialties portfolio includes a wide range of specialized thermoplastic compounds based on different base resins and fillers.

Note

• ᵍ 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.
• ᵖ 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.
• ⁷ 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.
• ¹¹ 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.
