Product brochure
The brochure groups plastic additives by what they do in the polymer. Every grade lists its CAS number and the resins where it works, so your formulator can match it against a known reference before you order.
Hindered phenol · phosphite · thioester
Primary hindered phenols 1010, 1076, 1098 and 3114; phosphites 168 and 626; thioester 300; ready blends 215 and 900. Processing and long-term thermal stability for PE, PP, PA, PS, ABS and polyester.
Benzophenone · benzotriazole · HALS
UV absorbers from BP-12 (UV-531) to UV-326, 327, 328 and 1577, plus HALS 292, 962 and 123. Grades for PVC, PP, PE, ABS, PU, coatings and inks; UV-1130 comes as a liquid for waterborne systems.
Optical brighteners · beta-diketones
OB, OB-1, KCB, KSN and ER brighteners give bluish white to PVC, PS, PE, PP, ABS, EVA foam, polyester melt and fibers. Beta-diketones and co-stabilizers hold color in PVC bottles, profiles and emulsion PVC.
Buying it right
Compounders buy additives for plastic by chemistry, not by brand. A 1010 antioxidant or a UV-531 absorber is the same molecule wherever it comes from, as long as the CAS number and purity match.
Every Chemtechnox and Chemtechsorb grade lists its CAS number and the resins where it works, so your formulator can check it against a known reference before the order.
The range covers PE, PP, PA, PVC, ABS and polyester, from wire and cable insulation to PVC windows and polyester fiber whitened in the melt.
The partnership
Experience
Documentation, logistics and compliance are routine here after three decades of cross-border trade. Hongda exports to more than 30 countries and works with over 500 distributors worldwide, so the paperwork your market requires has most likely been solved here before.
Support
Samples, datasheets and technical answers come straight from the team that makes the product. Formulation advice, matching against your current reference and follow-up after delivery are part of the partnership, included from the first order.
Product
Seven registered brands, from Dragon Dyes to Chemtech, all backed by Hongda's in-house R&D teams. Dyes, pigments, additives and functional chemicals come from the same group, so you can widen your catalogue while keeping a single supplier.
Supply
You buy at origin, in the quantities a distributor needs to stay competitive in its market. Volume pricing, consolidated shipments and production planned around your forecast give you the economics to defend margin against any local reseller.
