VALOX™ K3501 PBT Hydrolysis Resistant Resin. Passed USCAR Protocol

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

VALOX™ K3501 Resin is an Advanced Impact-Modified PBT (Polybutylene Terephthalate) Resin engineered to deliver excellent performance in Hot, Humid, and Moisture-Intensive Environments. developed as a Hydrolysis-Resistant Grade, this material offers enhanced Long-Term Property Retention compared to standard PBT Materials, making it particularly suitable for applications exposed to demanding Environmental Conditions.

Unlike Conventional Polyester Grades that may Experience performance degradation in the Presence of Heat and Moisture, VALOX™ K3501 is specifically formulated to provide improved Hydrolytic Stability. This allows Molded components to retain their Mechanical Properties, Dimensional Stability, and Overall Durability even after Prolonged exposure to Humid Operating Conditions.

The Resin also features an Impact-Modified Formulation, providing good Toughness and Resistance to Mechanical Stress. Components Molded from VALOX™ K3501 Resin can withstand Handling, Vibration, and Operational Impact while maintaining reliable Structural Performance. Combined with its balanced Flow Characteristics, the material supports efficient Molding and consistent Part Quality.

A Major benefit of VALOX™ K3501 is its proven performance against Automotive Environmental Durability Requirements, including passing the USCAR Hydrolysis Protocol. This Achievement Demonstrates the Material's ability to maintain performance in Severe Automotive and Industrial Environments where Heat, Moisture, and Long-Term exposure can Challenge Conventional Engineering Plastics.

For manufacturers seeking a Polyester Resin Capable of maintaining performance under Harsh Environmental Conditions, VALOX™ K3501 provides a reliable Solution. Its combination of Hydrolysis Resistance, Impact Strength, and Processing Stability makes it an excellent Choice for applications where Long-Term Durability is Critical.

RoHS Compliance: VALOX™ K3501 Resin Complies with RoHS Requirements, supporting Environmentally Responsible Product Development while maintaining Dependable Engineering performance and Long-Term Reliability.
