WESTON™ is a collection of high-purity liquid and solid phosphite antioxidants, and liquid phosphite esters. Designed to function as secondary antioxidants and synergize well with primary antioxidants such as hindered phenolics, WESTON™ is suitable for a variety of resins that require color, processing and thermal stability.
Versatile phosphite stabilizer that improves color, processing stability, and end-use of a variety of polymers; similar to WESTON® 398 but with food contact approvals.
Highly effective, phosphite-based color and molecular weight stabilizer for polymers, elastomers, and adhesives; similar to WESTON® 618F but with improved hydrolytic stability.
Nonylphenol-free phosphite antioxidant, designed as a drop-in replacement for TNPP with a 20% lower loading rate. Similar to WESTON® 705 but with improved hydrostability.
Diaryl phosphite ester antioxidant with a high phosphorus content and relatively low molecular weight. Improves color and light stability in polymers that do not require food contact.
Alkyl-aryl phosphite ester antioxidant that provides color and processing stability in polymers that do not require food contact approvals. Similar to WESTON® DPDP, but with a higher molecular weight and lower phosphorus content.
Versatile phosphite stabilizer that improves color, processing stability, and end-use of a variety of polymers; similar to WESTON® 399, but with a higher flash point.
