Songwon polymer stabilizers for the rubber, plastics and polymer industries are highlighted in the company's 32-page, four-color catalog, including Songnox antioxidants (phenolic antioxidants,
phosphite antioxidants and antioxidant blends), Songlight hindered amine light stabilizers (HALS) and Songsorb UV absorbers.
The electrodeposition coating composition has a resin solids content comprised of at least one binder with isocyanate-reactive groups and at least one polyisocyanate crosslinking agent blocked with at least one dihydrocarbyl
phosphite and/or at least one self-crosslinkable binder with isocyanate-reactive groups and with isocyanate groups blocked with at least one dihydrocarbyl
phosphite.
Weston 705 is a nonylphenol-free liquid
phosphite antioxidant approved for food contact in more than 180 countries.
We experimented with new combinations of existing traditional phenol and
phosphite stabilizers, as well as some new hyperactive stabilizer technologies.
The electrodeposition coating composition has a resin solids content is comprised of at least one binder with isocyanate-reactive groups and at least one polyisocyanate crosslinking agent blocked with at least one dihydrocarbyl
phosphite and/or at least one self-crosslinkable binder with isocyanate-reactive groups and with isocyanate groups blocked with at least one dihydrocarbyl
phosphite.
Tris(nonylphenyl)
phosphite (TNPP) was obtained from Aldrich and used as received.
Its claim to fame is that it can reduce the use of
phosphite antioxidants in polyolefins and assist in switching away from TNPP.
Mitamura, Sengoku and Tanaka developed a stable, transparent PVC material consisting of 100 parts by weight PVC, 0.01 to 10 parts zinc salts, 0.01 to 10 parts zinc-modified hydrotalcite compounds, and 0.01 to 3 parts
phosphite ester compounds.
The solubility of a commercial aryl
phosphite processing stabilizer for polyolefins, {tris (2,4-di-t-butylphenyl)-phosphite} (Irgafos 168.
is the leading supplier of the common thermal stabilizer tris(4-nonyl-phenyl)
phosphite (TNPP).
CEO Peter Smith says some of the milestones already achieved by the new entity include commercialization of Polybond polymer modifiers derived from renewable resources and completion of Phase I of capacity expansions for
phosphite antioxidants in South Korea and for hindered phenolics in Saudi Arabia.
