| Product Name | Product Description |
| WESTON® 439 phosphite ester | WESTON® 439 phosphite ester is used to improve the color and light stability and clarity of PVC and vinyl chloride copolymers. |
| WESTON® DHOP phosphite ester | WESTON® DHOP phosphite ester is a high molecular weight phosphite which has a relatively high phosphorus content. It has a free hydroxyl number of approximately 20 mg KOH/g. WESTON DHOP phosphite is useful as a secondary stabilizer for PVC resins where regulatory approval for food contact is not required. |
| WESTON® DPDP phosphite ester | WESTON® DPDP phosphite ester is an alkyl-aryl phosphite which is used as a color and processing stabilizer in polycarbonate, polyurethanes, ABS polymers, and coatings where regulatory approval for food contact is not required. It is also used as a secondary stabilizer in polyvinyl chloride. |
| WESTON® DPP phosphite ester | WESTON® DPP phosphite ester is a diaryl phosphite which can be used to improve the color of unsaturated polyesters. In polyolefins, WESTON® DPP phosphite ester can be used as a stabilizer in applications where regulatory approval for food contact is not required. It is also used as a secondary stabilizer to improve the light and color stability and to prevent plate-out of polyvinyl chloride. This product has a high phosphorus content and a relatively low molecular weight. |
| WESTON® DPTDP phosphite ester | WESTON® DPTDP phosphite ester |
| WESTON® EHDP phosphite ester | WESTON® EHDP phosphite ester is an alkyl-aryl phosphite which can be used as a color and processing stabilizer in ABS, polycarbonate, polyurethane, coatings, and PET fiber where regulatory approval for food contact is not required. It can be used as a secondary stabilizer to improve color and heat stability in PVC. |
| WESTON® PDDP phosphite ester | WESTON® PDDP phosphite ester is an alkyl-aryl phosphite which can be used as a color and processing stabilizer in ABS, polycarbonate, polyurethane, coatings, and PET fiber where regulatory approval for food contact is not required. |
| WESTON® PNPG phosphite ester | WESTON® PNPG phosphite ester is a specialty alkyl-aryl phosphite with a very high phosphorus content. It is an effective secondary stabilizer for a variety of polymers. |
| WESTON® PTP phosphite ester | WESTON® PTP phosphite ester is a specialty product useful when a high molecular weight phosphite is needed. It has a free hydroxl number of approximately 275 mg KOH/g. WESTON® PTP phosphite ester is used in foamed polyurethanes to control color development and prevent bun scorching. |
| WESTON® TDP phosphite ester | WESTON® TDP phosphite ester is a trialkyl phosphite which is useful as a secondary stabilizer in ABS, polyethylene terephthalate, PET fibers, coatings, lubricants, PVC, polycarbonate and polyurethanes. It can also be used in polyolefins where regulatory approval for food contact is not required. |
| WESTON® TLP phosphite ester | WESTON® TLP phosphite ester is a trialkyl phosphite which can be used as a lubricant additive to improve antifriction and antiwear characteristics. It also functions as a sulfur deactivator. |
| WESTON® TPP phosphite ester | WESTON® TPP phosphite ester is a versatile aryl phosphite which can be used as a stabilizer in many types of polymers. |
