In the world of modified plastics, unbalanced material performance often becomes a bottleneck for product upgrades — strong impact resistance may lead to hazy coloration; eye-catching appearance might fail to meet moisture-heat impact requirements. That’s where KINGFOX Impact Modifier USI-3310 comes in as the "Master of Balance," engineered to solve this dilemma.
From precision electronic enclosures to outdoor equipment, no matter how harsh the application scenario, it enables simultaneous enhancement of impact resistance and color performance, truly achieving "no compromise" across coloration, moisture-heat resistance, weather resistance, impact resistance, and chemical resistance. Next, a set of actual test data will unveil the performance indicators of KINGFOX USI-3310. For more measured data, please contact your dedicated sales consultant!
