VALOX™ 357X Advanced Impact Modified Flame Retardant PBT+PC Blend

Enhanced Chemical Resistance for Electrical Industrial Applications

VALOX™ 357X Resin is an Advanced Impact-Modified Flame-Retardant PBT+PC Blend engineered to provide an excellent balance of Chemical Resistance, Impact Strength, Flame Retardancy, and Processing Efficiency. Developed for demanding Electrical and Industrial applications, this Grade combines the Strengths of Polybutylene Terephthalate (PBT) and Polycarbonate (PC) to deliver a durable and reliable Engineering material Capable of Meeting Stringent performance Requirements.

A Major benefit of VALOX™ 357X is its enhanced Chemical Resistance, allowing Molded components to perform reliably when exposed to Oils, Greases, Cleaning Solutions, and various Industrial Chemicals. This Resistance helps preserve both Mechanical Integrity and appearance throughout Long-Term Service, particularly in Harsh Operating Environments where material Durability is Critical.

The Resin Utilizes an Impact-Modified formulation to Improve Toughness and Resistance to Mechanical Shock. Parts Molded from VALOX™ 357X Resin Exhibit excellent Impact Performance, helping them withstand Assembly Stresses, Transportation, Handling, and demanding Operating Conditions without Compromising Structural Stability.

In addition to its Mechanical and Chemical Durability, VALOX™ 357X offers Ease of Processing, enabling efficient Molding of Complex Geometries while maintaining Dimensional Consistency and Surface Quality. The balanced Flow characteristics support stable Production and Help manufacturers achieve consistent Part performance across a Wide range of applications.

Engineered specifically for the Electrical and Industrial Sectors, VALOX™ 357X delivers the Flame-Retardant performance required for Safety-Critical applications. Its combination of Impact Strength, Chemical Resistance, and reliable Processing makes it a practical material Choice for Electrical Housings, Connectors, Industrial Equipment, and other components where Long-Term reliability is Essential.

RoHS Compliance: VALOX™ 357X Resin supports RoHS Requirements, helping manufacturers reduce the use of Restricted Hazardous Substances while maintaining Dependable Engineering Performance.
