VALOX™ 325 PBT General Purpose Resin with High Heat & High Gloss

Good Stiffness, Excellent Chemical Resistance with Ease of Processing

VALOX™ 325 Resin is a General-Purpose Semi-Crystalline PBT (Polybutylene Terephthalate) Engineering Resin developed to provide a versatile combination of High Heat Performance, attractive Surface Appearance, Chemical Resistance, and easy Processability. Designed for a Wide range of Molding applications, this Grade delivers Value-Added properties that Help manufacturers achieve both Functional performance and Aesthetic Quality.

One of the Distinguishing features of VALOX™ 325 is its ability to Combine High Heat Stability with a High-Gloss Finish. Components Molded from this material maintain their appearance and Dimensional Integrity when exposed to Elevated Temperatures, making it suitable for applications where both Thermal performance and Visual Appeal are Important.

The material also offers good Stiffness and Mechanical Strength, helping finished Parts retain their Shape under Load while maintaining reliable Long-Term Performance. Its Semi-Crystalline Polyester Structure contributes excellent Dimensional Stability, making it a Dependable Choice for Precision-Molded Components.

Another Key benefit of VALOX™ 325 Resin is its excellent Chemical Resistance. The material Performs well when exposed to Oils, Greases, Fuels, Detergents, and Many Industrial Chemicals, helping Extend Component Lifespan in demanding Operating Environments.

From a Manufacturing Perspective, VALOX™ 325 is engineered for easy Processing, allowing efficient Molding of Complex Parts while maintaining consistent Quality and Surface Finish. This balance of Processability and performance makes the Grade a practical Solution for manufacturers seeking reliable Production and durable End-Use Products.

Rather than focusing on a Single performance Attribute, VALOX™ 325 delivers a Well-Rounded combination of Thermal Stability, Appearance, Stiffness, and Chemical Durability, making it one of the more Versatile Grades within the VALOX™ PBT Portfolio.

RoHS Compliance: VALOX™ 325 Resin supports RoHS Requirements, helping manufacturers reduce the use of Restricted Hazardous Substances while maintaining Dependable Engineering Performance.
