Features & Benefits

Superior Flow for Complex Molds

The high MVR (36) ensures easy filling of intricate and thin-walled designs, reducing injection pressure and cycle times for higher productivity.

Built-In Durability and Clarity

UV stabilization protects against yellowing and degradation from sunlight, maintaining optical clarity and mechanical integrity for long-lasting outdoor or illuminated components.

Inherent Flame Resistance and Safety

The UL94 V2 rating provides a recognized level of flame retardancy without halogens, contributing to safer products and helping meet regulatory requirements for electronics and enclosures.
