OUTSTANDING ALL-AROUND PERFORMANCE
WESTON® 705 PROVIDES EXCEPTIONAL
ALL-AROUND PERFORMANCE
Compared to benchmark phosphite antioxidant used in elastomers, TNPP, WESTON® 705 has up to 20% higher content of phosphorus and more reactive structures to protect polymer after reaction and during storage. This preserves the desired polymer structure for final applications.
WESTON® 705 is a true liquid antioxidant that can be easily incorporated in the existing elastomer solution or emulsion process. Its high solubility in organic solvents used in elastomer industry and liquid form provide a clear advantage to other alternative products. In addition, its clean NIAS (Non-Intentionally Added Substances) profile and most recent FDA approval in styrene block copolymers make it the safest antioxidant in the industry, which will give consumers peace of mind.
UP TO 3X LONGER RETENTION OF PHYSICAL PROPERTIES
Provides better storage stability with up to 3X longer retention of Mooney Viscosity in heat aging test.
IMPROVED COLOR RETENTION
Significantly better color retention for longer customer satisfaction.
FREE OF ODOR
Sulphur-free chemistry provides odor-free, end-use applications.
