Key Features & Advantages | |
Exceptional Migration & Blooming Resistance: | Guarantees no color transfer to adjacent materials or surface bloom, ensuring product cleanliness and long-term performance integrity. This is its most critical advantage in rubber. |
Outstanding Sulfur Vulcanization Stability: | Uniquely formulated to withstand standard to high-temperature sulfur curing processes (typically up to160°C) without fading or causing curing interference. |
Excellent Dispersibility: | Ensures uniform color distribution within the rubber compound, leading to consistent batch-to-batch shade and optimal physical properties of the final product. |
Good Heat & Aging Resistance: | Maintains color stability under thermal stress and during the aging of rubber articles, contributing to product durability. |
Cost-Effective Performance: | Delivers a superior balance of critical fastness properties and color strength at a competitive cost, offering outstanding value for mass production. |
