VALOX™ 771 PBT 35% Glass Reinforced Resin. Good Flame Retardant Rating

Excellent Chemical Resistance, CTI Rating 0 & Low Shrinkage Properties

VALOX™ 771 Resin is a 35% Glass Fiber Reinforced Flame-Retardant PBT (Polybutylene Terephthalate) Engineering Resin designed to deliver an Exceptional combination of High Heat Resistance, Chemical Resistance, Dimensional Stability, and Electrical Performance. developed for demanding Electrical and Electronic applications, this Grade provides a robust material Platform for components requiring both Mechanical Strength and Stringent Safety Compliance.

The Incorporation of 35% Glass Fiber Reinforcement significantly enhances the Stiffness, Strength, and Dimensional Stability of VALOX™ 771. This Reinforced Structure helps reduce Shrinkage and Minimize Warpage during Molding, enabling manufacturers to produce Precision components with excellent Dimensional Consistency. The Low-Warpage characteristics make the material particularly attractive for Tight-Tolerance applications where Assembly Accuracy is Critical.

A Major Advantage of VALOX™ 771 Resin is its excellent Chemical Resistance and Thermal Stability. Components Molded from this Grade maintain their performance when exposed to Oils, Greases, Cleaning Solutions, and various Industrial Chemicals. In addition, the material Demonstrates excellent Heat Resistance, supporting reliable Operation in Elevated-Temperature Environments commonly encountered in Electrical and Industrial Systems.

The Resin also offers Strong Electrical Insulation Performance, including a High Comparative Tracking Index (CTI) and excellent Relative Thermal Index (RTI) Characteristics. These properties Help Improve Electrical reliability and Safety in applications exposed to Voltage Stress and Challenging Environmental Conditions. Additional Benefits include good Color Stability, good Adhesion to Epoxy Systems, and Laser Markability, providing greater flexibility for Identification, Assembly, and Manufacturing Processes.

Rather than focusing Solely on Flame Retardancy, VALOX™ 771 combines Thermal Performance, Electrical Reliability, Mechanical Strength, and Dimensional Stability into a Single Engineering Material. This balanced Property Profile makes it a preferred Choice for manufacturers seeking a High-Performance Reinforced Polyester for critical Electrical and Industrial Components.

RoHS Compliance: VALOX™ 771 Resin supports RoHS Requirements, helping manufacturers reduce the use of Restricted Hazardous Substances while maintaining Dependable Engineering Performance.
