VALOX™ 3706 Unreinforced Impact Modified Flame Retardant PBT+PC Resin

Chemical Resistance for Outdoor Electrical Industrial Applications

VALOX™ 3706 Resin is an Unreinforced Impact-Modified Flame-Retardant PBT+PC Blend engineered to provide a balanced combination of Impact Strength, Chemical Resistance, Thermal Stability, and Outdoor Durability. Developed for Electrical and Industrial applications, this Advanced Polyester Alloy combines the Benefits of Polybutylene Terephthalate (PBT) and Polycarbonate (PC), resulting in a material that Performs reliably in demanding Environments where both Mechanical Toughness and Flame Resistance are required.

The PBT Portion of the Blend contributes excellent Chemical Resistance, Dimensional Stability, and Mechanical Strength, while the Polycarbonate Component enhances Impact Resistance and Toughness. This Synergy allows VALOX™ 3706 to maintain performance under Mechanical Stress, Environmental Exposure, and varying Operating Conditions without Compromising Long-Term Reliability.

A Key Advantage of VALOX™ 3706 Resin is its suitability for Outdoor Electrical and Industrial applications. The material Exhibits Strong Resistance to Oils, Greases, Cleaning Agents, Moisture, and other Environmental Contaminants that can affect Component Durability. This Chemical Resistance helps preserve both appearance and Functionality throughout the Service Life of the finished Product.

The Impact-Modified formulation provides improved Toughness compared to Conventional Flame-Retardant Polyester Materials, helping Molded Parts withstand Handling, Transportation, Assembly, and Operational Impacts. Combined with its Flame-Retardant Performance, the Resin offers a Dependable Solution for Safety-Critical applications exposed to demanding Conditions.

Engineers often Select VALOX™ 3706 when they require a material that Balances Flame performance with Environmental Durability. Its Unreinforced Construction also allows for good Surface Quality and Molding Versatility, making it suitable for Complex Component Designs where Toughness, Chemical Resistance, and Dimensional Stability are Equally Important.

RoHS Compliance: VALOX™ 3706 Resin supports RoHS Requirements, helping manufacturers reduce the use of Restricted Hazardous Substances while maintaining Dependable Engineering Performance.
