Organic pigments and polymer-soluble dyes include yellows and reds with sufficient heat stability to substitute for inorganic pigments. Comprehensive line of colorants FDA-approved for food contact packaging.
PV Fast pigments provide superior properties and include quinacridones, phthalocyanine blues and greens, and special azos. Graphtol pigments include diarylides, metal salt azo reds and other azo colors.
Dyes for polymers include Hostaperm, Hostasol, and Polysynthren lines. Leucopure and Hostalux are optical brighteners for use in polymers.
Broad selection of hindered amine light stabilizers from monomeric, oligomeric, to photereactive include Hostavin N20 and N24 monomeric HALS for polyolefins. Hostavin N24 recommended for acrylics and geotextile applications. Both products are suitable for pigmented thick-section applications.
Hostavin N30 FDA-approved oligomeric HALS provides enhanced long-term thermo-oxidative stability to polyolefins allowing for a reduction in primary antioxidant needs, which can translate into better overall initial in PE applications. Greater solubility and compatibility decrease plate-out, migration and blooming during and after film fabrication.
Nonhydroxy substituted uv absorbers as well as standard uv absorbers. Sanduvor VSU (oxalanilide family) white, free-flowing polar uva with low volatility and superior absorptivity and sharp cutoff below 350 nm recommended for polyamide, polyesters, PVC, styrenics, PC, polyacetals, PMMA, and several coating-related applications including unsaturated polyesters, polyurethane and acrylic resins. Because of product's sharp cutoff below 350 nm, it does not inhibit fluorescent pigment at lower wavelengths. As a nonhydroxy substituted uv absorber, Hostavin VSU does not interact with catalytic impurities, which cause major discoloration, and is inert to radical chemistries that lead to discoloration.
Hostavin PR 25 (benzylidene malonate ester) nonhydroxy substituted uv absorber with absorptivities above 100 liters has a lambda maxima at 310 nm and sharp cutoff at 350 nm. Polar soluble and clean looking, product specifically designated for applications that require low discoloration and uv protection during early stages of exposure. Recommended for PVC, styrenics, acrylics, PC and polyesters. Inert to radical chemistries and catalytic impurities.
Additive modifier Nylostab SEED is recommended for the stabilization of nylon. It is white, free-flowing and offered for thick- and thin-section nylon resins. Highly polar and with extremely low volatility, Nylostab SEED is unrestricted in use in all polyamide chemistries including the new transparent nylons.
A new coupling agent and compatibilizer is specially designed for natural fi bers in polypropylene.
A new highly polar metallocene PE wax grafted with maleic anhydride is designed for bonding and compatibilization of natural fibers in polyethylene composites.
The latest K show was rich in additives that can ease processing and end-use problems of thermoplastics and thermosets.
This year’s show will present such a large number of new polymer additives that only a few categories can be covered this month: antioxidants, halogen and non-halogen flame retardants, PVC heat stabilizers, and impact modifiers. Next month, we’ll report on new uv stabilizers, colorants, additive concentrates, lubricants, and more.
