VALOX™ ENH3500 PBT General Purpose FR Resin with Chemical Resistance

Non-Brominated Non-Chlorinated Flame Retardant. Good Impact Strength

VALOX™ ENH3500 Resin is an Environmentally Responsible Non-Brominated, Non-Chlorinated Flame-Retardant PBT (Polybutylene Terephthalate) Engineering Resin designed to provide an excellent balance of Flame Performance, Chemical Resistance, Impact Strength, and Sustainability. Developed for applications requiring Halogen-Free Flame Retardancy, this Grade offers a Modern material Solution that supports Environmental Initiatives without Compromising Engineering Performance.

A Key Feature of VALOX™ ENH3500 is its Non-Brominated and Non-Chlorinated Flame-Retardant Formulation. This Halogen-Free Approach helps manufacturers address increasingly Stringent Environmental and Regulatory requirements while maintaining the Fire Safety performance required for Electrical and Industrial Components. The material supports the Growing demand for more Sustainable Engineering Thermoplastics across Multiple Industries.

In addition to its Environmental Benefits, VALOX™ ENH3500 Resin delivers excellent Chemical Resistance, enabling components to withstand exposure to Oils, Greases, Cleaning Agents, and various Industrial Chemicals. This Durability helps maintain Long-Term Mechanical Integrity and Appearance, even in Challenging Operating Environments.

The Resin also provides good Impact Strength, allowing Molded Parts to Resist Handling Damage, Assembly Loads, and Operational Stresses. Combined with the Inherent Dimensional Stability and Thermal performance of PBT, this balanced Property Profile makes the material suitable for applications requiring both Toughness and Reliability.

For Product Designers seeking a Sustainable Flame-Retardant Polyester, VALOX™ ENH3500 offers an attractive combination of Environmental Responsibility and Engineering Performance. Its Halogen-Free Flame Retardancy, Chemical Durability, and Impact Resistance make it well suited for Modern Electrical, Electronic, and Industrial applications where Safety and Sustainability are Equally Important.

RoHS Compliance: VALOX™ ENH3500 Resin supports RoHS requirements and aligns with the Industry's Move toward Environmentally Conscious material Solutions while maintaining Dependable performance in demanding applications.
