Features & Benefits

Superior Flame Retardant Performance

VALOX 771 achieves a UL94 V-0 rating at just 0.75mm, ensuring critical safety in thin-walled components. This allows for design flexibility without compromising on fire safety in enclosures and connectors.

Exceptional Electrical Safety

With a CTI of 0 and high arc resistance, VALOX™ FR resin 771 withstands electrical arcing. This prevents tracking and failure in high-voltage environments, enhancing the reliability and lifespan of electrical parts.

Reliable Mechanical & Thermal Strength

This grade maintains high mechanical strength and heat resistance (HDT up to 217°C). It ensures dimensional stability and performance under load and in high-temperature operating conditions.
