Weston ® DPP is a diaryl phosphite ester which has a high phosphorus content, relatively low molecular weight and can be used to improve the color of unsaturated polyesters. It can also be used as a stabilizer in polyolefin applications where regulatory food contact approval is not required. Weston ® DPP also serves as a secondary stabilizer to improve the light/color stability and to prevent plate-out of PVC.
Weston® TNPP is a cost-effective phosphite stabilizer that improves color and processing stability during recovery, drying, compounding, processing and end use. Typically used with HDPE, LLDPE, SBR, ABS, PVC.
Weston® 705 is an industry pioneering phosphite stabilizer which is free of nonylphenol. It can be used in a variety of polymer systems such as HDPE, LLDPE, SBR, NBR, SBC, SBS, ABS, PVC. Based on proprietary chemistry and technology, it has been developed as a replacement for TNPP wherever a TNPP alternative is sought.
High molecular weight phosphite ester which has relatively high phosphorus content and a free hydroxyl number of approximately 20 mg KOH/g. It is useful as a secondary stabilizer for PVC where regulatory approval for food contact is not required.
Weston® EHDP is a color and processing stabilizer in ABS, polycarbonate, polyurethane, coatings, and PET fiber not requiring food contact approval. It can be used as a secondary stabilizer for improving color and heat stability in PVC.
Weston® LPP (Liquid Productivity Platform) antioxidants have been designed as an alternative for conventional powder (solid) antioxidants. Liquid productivity technology enables the creation of customized blends that meet requirements of cost-effective performance and enhanced Responsible Care®.
Addivant is the world’s largest producer of liquid phosphites, specialty antioxidants and additives in non-dust forms, including its patented ANOX® NDB® stabilizer blend technology that enables up to eight components to be delivered in a single homogeneous blend.
