VALOX™ K4560 30% Glass Reinforced PBT Resin. Passed USCAR Protocol

High Flow, Impact with Property Retention in Hot & Humid Environment

VALOX™ K4560 Resin is a 30% Glass Fiber Reinforced PBT (Polybutylene Terephthalate) Resin engineered for applications that require High Flow Characteristics, Hydrolysis Resistance, and Long-Term Durability under Hot and Humid Conditions. As Part of the VALOX™ Hydrostable Resin family, this Grade is specifically formulated to maintain critical Mechanical properties when exposed to Challenging Environmental Conditions that can Negatively Impact Conventional Polyester Materials.

The combination of 30% Glass Fiber Reinforcement and a High-Flow formulation provides an excellent balance of Strength, Stiffness, Dimensional Stability, and Processing Efficiency. The enhanced Flow characteristics allow manufacturers to Mold Complex Geometries and Thin-Wall components more easily while maintaining excellent Structural performance and Production Consistency.

A Key Differentiator of VALOX™ K4560 is its improved Hydrolytic Stability. Unlike standard PBT Grades, this material is designed to retain Mechanical properties after prolonged exposure to Heat and Humidity. This capability makes it particularly suitable for applications operating in Harsh Environments where Moisture Resistance and Long-Term reliability are Essential Requirements.

In addition to its Environmental Durability, VALOX™ K4560 Resin offers good Impact performance and excellent Dimensional Stability. The Glass Reinforcement helps reduce deformation under Load while maintaining Part Accuracy over Extended Service Life. These characteristics are especially valuable for Automotive, Electrical, and Industrial components requiring consistent performance under demanding Operating Conditions.

The Resin has also passed the USCAR Hydrolysis Protocol, Demonstrating its ability to withstand Severe Automotive Environmental Testing Requirements. This Achievement Highlights the Material's suitability for applications where Long-Term Property Retention is critical to Product reliability and Service Life.

RoHS Compliance: VALOX™ K4560 Resin Complies with RoHS Requirements, supporting Environmentally Responsible Manufacturing Practices while delivering Dependable Engineering performance in demanding applications.
