Triphenyl phosphite. It acts as a chelating agent. Exhibits compatibility with PVC.

Lankromark™ LE571 by Valtris Specialty Chemicals is a phenol-free, highly efficient chelating agent and co-stabilizer based on tris-alkylphosphite. It also acts as a secondary antioxidant, reducing discoloration in the processing of other organic materials such as PP, PE, rubber and PU. It is used in combination with barium/zinc and calcium/zinc soap stabilizers in PVC for light stabilization.

• It is used in ABS, polyethylene terephthalate, polycarbonate and other polyolefins where food contact approval is not required.
• Lankromark™ LE571 is suitable for processing by extrusion, injection molding, calendering, rotational molding and spread coating.
• It is recommended for structural foams, flooring, roofing, film and sheet applications.

Quent® DPDP by Qualichem Specialties is Alkyl aryl phosphite. Acts as a very good antioxidant for acrylics, polyesters & polyphenylene oxide which improves the color retention during the processing of these polymers. Also acts as a chelating agent in liquid PVC stabilizers. Improves heat & light stability properties in PVC plastics. Is a non-polluting stabilizer for styrene butadiene rubbers. Quent® DPDP can be used with metal soap in processing of PVC to improve color & weathering resistance of products.

CHPHOS® 8621 by Changhe Chemical New Material (Jiangsu) acts as a stabilizer and chelating agent. It offers good color inhibition and, increases oxygen resistance and photostability. CHPHOS® 8621 is suitable for acrylonitrile butadiene styrene (ABS), polyurethane (PU), polyacrylamide (PAM) and polyvinyl chloride (PVC).

CHPHOS® PDOP by Changhe Chemical New Material (Jiangsu) is an aryl alkyl phosphite antioxidant. It acts as an efficient auxiliary stabilizer and chelating agent in hard or soft PVC materials. It improves the brightness, uniformity, transparency, and thermal stability of PVC. It provides good color improvement and thermal stability during processing and post-processing. CHPHOS® PDOP is suitable for polyolefins, acrylonitrile butadiene styrene (ABS), polyurethane (PU), polyacrylamide (PAM), polyvinyl chloride (PVC) and polyethylene terephthalate (PET) fibers. The recommended dosage level is 0.1 to 2.0%.

Aminoethylethanolamine (AEEA) by Dow is a versatile epoxy curing agent, chelating agent and surfactant. It is a building block in the manufacture of specialty corrosion inhibitors. It is a single-component product, with minimal ethylenediamine impurity.

• It offers consistent and predictable reaction products, easily derivatized, low vapor pressure and high viscosity.
• It provides low environmental impact-, sensitivity and is suitable for harsh conditions.
• It is used in urethane chemicals, textile, lube oil and fuel additives.
• Aminoethylethanolamine (AEEA) complies with TSCA, EINECS, EU Directive 2011/65/EU (RoHS), EU Directive 2002/96/EC (WEEE), EU Directive 94/62/EC and CONEG.

VERSENE™ 100 Chelating Agent by Dow is a chelating agent. It is an aqueous solution of the tetrasodium salt of ethylenediaminetetraacetic acid. It chelates most multivalent metal ions (e.g., Fe, Cu, Mn, Ca, Mg, Zn) in a 1:1 molar ratio.

• Also, chelates most transition metals below pH 12.
• It is stable under varying conditions of temperature, acidity, alkalinity, and the presence of other chemicals.
• It is attached, however, by strong oxidizing agents such as hypochlorite bleach.
• VERSENE™ 100 Chelating Agent is scale dissolver for cooling tower cleaning.

Di-2-Ethyl hexyl Monophenyl Phosphite. Acts as a chelating agent, heat stabilizer, light stabilizer and an antioxidant. Exhibits solubility in organic solvents, and insolubility in water. Widely used in PVC products (for medical equipment products, transparent tubes, plastic, heat shrink film). Can also be used for PE, PP, ABS.

VERSENE™ 220 Crystals by Dow is a chelating agent. This tetrasodium ethylenediaminetetraacetate tetrahydrate offers freight savings over VERSENE™ 100.

• It also contains less impurities than VERSENE™ 100.
• VERSENE™ 220 Crystals is useful in formulating dry products or where the total water content of a product must be kept to a minimum.
• It is used in polymerization applications.

VERSENEX™ 80 by Dow is a chelating agent. It is an aqueous solution of the pentasodium salt of diethylenetriaminepentaacetic acid, Na₅DTPA.

• The chelant is used in the presence of oxidizers such as peroxide and when metal chelates of greater stability or solubility are sought.
• VERSENEX™ 80 is used in indirect food contact and polymerization applications.
