Engineering Plastic Antistatic Agent High-Temp Alkylamine Solid, Excellent Heat Stability Indirect Food-Contact for High-Temp Processing
This high‑temperature alkylamine solid antistatic agent is a non‑ionic migratory antistatic additive designed for engineering plastic modification. Optimized alkyl molecular structure delivers outstanding thermal stability, resisting decomposition and volatile emission during high‑temperature compounding and molding operations. After melt processing, active ingredients gradually migrate to the plastic surface and construct a hydrophilic conductive layer for static dissipation. This product meets
Product DetailsThis solid alkylamine antistatic additive features long‑chain saturated alkyl backbone with hydrophilic hydroxyethyl functional groups. The saturated hydrocarbon molecular architecture enhances thermal resistance, reducing decomposition, smoking and discoloration risks when engineering plastics undergo high‑shear, high‑temperature twin‑screw compounding and subsequent injection molding. It can be directly blended with resin pellets or manufactured into antistatic masterbatch prior to plastic processing.
After molded engineering plastic articles cool and solidify, the antistatic molecules slowly migrate outward toward the material surface. Hydrophilic polar groups absorb trace ambient moisture to form a thin continuous hydrophilic surface film. This conductive layer dissipates accumulated static charges and reduces dust adhesion on finished components. The product complies with indirect food‑contact requirements, making it suitable for engineering‑plastic parts that have non‑direct contact with food such as structural housings, supporting frames and transport trays.
As a migratory non‑ionic antistatic additive, its antistatic performance is humidity‑dependent. Antistatic effectiveness decreases under extremely dry environmental conditions. Excessive loading will cause surface blooming, slippage, and deterioration of painting, printing and adhesive bonding properties of engineering plastic workpieces. For high‑melting‑point engineering resins, processing temperature must be strictly controlled; excessive barrel temperature will still trigger partial thermal degradation of the amine‑based additive.
Typical recommended dosage ranges from 0.6 wt%‑1.9 wt% based on total resin weight. Pre‑production laboratory testing is mandatory to evaluate thermal stability during compounding, migration speed, surface resistivity, blooming tendency, color retention, mechanical property retention and surface coating adhesion before mass‑scale manufacturing. Food‑contact compliance verification of final molded articles should be completed according to relevant regional regulations.
Store the solid antistatic product in sealed moisture‑proof bags inside cool, dry and ventilated warehouse. Avoid long‑term high‑temperature storage that may result in caking. Prevent direct sunlight exposure. Reseal packaging promptly after opening to maintain consistent physical state and processing performance.
