POM Impact Modifier (MBS Core-Shell)
# Product Application Overview
This product is a specialized impact-resistant toughening modifier developed specifically for polyoxymethylene (POM), intended solely for toughening and modification of POM engineering plastics. It is compatible with various conventional POM processing processes, addressing inherent issues of POM inherent issues such as low-temperature brittleness, low weld strain strength, and high formaldehyde emissions. While enhancing POM toughness, it retains the original rigidity and thermal properties of POM, helping modified POM meet performance and environmental requirements across various end-use fields.
