VCI Additive Masterbatch

VCI Masterbatch A concentrated polymer additive (typically PE/PP-based) containing ‌5–30% vapor corrosion inhibitors‌ that release protective molecules to prevent metal oxidation. ‌Core Mechanism Forms ‌nanoscale protective films‌ on metal surfaces through continuous vapor release. Disrupts electrochemical corrosion by blocking moisture/oxygen contact. ‌Key Features‌ ‌Compatibility‌: Works with PE, PP, PET, and engineering plastics. ‌Dosage‌: 2–4% blend ratio for films/bags; 5–20% for injection molds. ‌Eco-Safe‌: Halogen-free formulations comply with RoHS/REACH. ‌Applications‌ ‌Packaging‌: Anti-rust films for automotive parts, electronics. ‌Industrial‌: Protective coatings for machinery and steel components.

Flame Retardant Additive Masterbatch

Flame Retardant Additive Masterbatch Concentrated polymer carriers (e.g., PE, PP) loaded with ‌15–60% flame-retardant compounds‌, including halogen-free agents like aluminum trihydroxide (ATH) or synergistic phosphorus-nitrogen systems. These additives inhibit combustion by forming protective char layers and quenching free radicals during thermal exposure. ‌Key Mechanisms‌ ‌Gas Phase Inhibition‌: Releases non-flammable gases (e.g., water vapor from ATH) to dilute oxygen. ‌Char Formation‌: Creates insulating carbon barriers that shield substrates from heat/flames. ‌Critical Performance‌ Achieves ‌UL94 V-0/V-1 ratings‌ in polyolefins and engineering plastics. ‌Thermal Stability‌: Processes at 180–260°C without decomposition. ‌Low Smoke Emission‌: Halogen-free variants reduce toxic fume generation. ‌Applications & Dosage‌ ‌Dosage‌: 5–20% in cables, 10–30% in electrical enclosures. ‌Uses‌: Automotive connectors, building materials, electronic housings.

Anti Static Additive Masterbatch

PE Anti-Static Additive Masterbatch Concentrated masterbatch incorporating ‌15-40%‌ specialized anti-static agents (e.g., ethoxylated amines, glycerol esters) into PE carriers, designed to impart ‌permanent or migratory static dissipation‌ in films, packaging, and industrial parts. Achieves surface resistivity of ‌10⁸–10¹² Ω/sq‌. ‌Key Features‌ ‌Rapid Charge Dissipation‌: Reduces static decay to <2 seconds (ESD-safe per ANSI/ESD S20.20). ‌Thermal Stability‌: Compatible with processing at 160–230°C without degradation. ‌Low Migration‌: Non-oily formulation prevents surface bloom or contamination4. ‌Technical Benefits‌ Prevents dust adhesion, spark risks, and equipment jamming. Maintains clarity in transparent films (no haze). Minimal impact on mechanical properties (tensile strength ±5%). ‌Applications & Dosage‌ ‌Dosage‌: 2–5% in films, 5–10% in rigid parts. ‌Uses‌: FIBC bags, electronic packaging, automotive fuel tanks, conveyor components.
