Release agent


Release agent is a functional substance between the mold and the finished product. Release agents are chemically resistant and do not dissolve when in contact with the chemical composition of different resins (especially styrene and amines). The release agent also has heat resistance and stress resistance, and is not easy to decompose or wear; The release agent adheres to the mold and does not transfer to the part being processed and does not interfere with painting or other secondary processing operations. Due to the rapid development of injection molding, extrusion, calendering, molding, lamination and other processes, the amount of release agent has also increased significantly.
1. Classified by usage: internal release agent, external release agent;
2. Classification by life: conventional release agent, semi-permanent release agent;
3. Classification by form: Solvent release agent, Water-based release agent, Solventless release agent, Powder release agent, Paste release agent
4. Classification by active substance:
① Silicon series-mainly silicone compounds, silicone oil, silicone resin methyl branched silicone oil, methyl silicone oil, emulsified methyl silicone oil, hydrogen containing methyl silicone oil, silicone grease, silicone resin, silicone rubber, silicone rubber toluene solution,
② Wax series-plant, animal, synthetic paraffin; microcrystalline paraffin wax, polyethylene wax, etc.
③ fluorine series-the best isolation performance, mold pollution is small, but the cost is high PTFE; Fluororesin powder; fluororesin coating, etc.
④ Surfactant series-metal soap (anionic), EO, PO derivatives (nonionic)
Inorganic powder series-talc, mica, clay, white clay and so on
⑥ Polyether series-polyether and fatty oil mixture, heat resistance is good chemical, mostly used in some rubber industries with restrictions on silicone oil. The cost is higher than that of silicone oil series.
① Release property (lubricity). it is possible to form a uniform thin film and a mol article having a complex shape with accurate size.
② Good demoulding continuity.
3. The appearance of the formed product is smooth and beautiful, and the adhesion of dust is not caused by the sticky release agent.
④ Excellent secondary processing. When the mold release agent is transferred to a molded article, it has no adverse effect on processed articles such as plating, hot stamping, printing, coating, and bonding.
⑤ Easy coating.
⑥ heat resistance.
⑦ pollution resistance.
good forming, high production efficiency.
good stability. When used with compounding agent and material, its physical and chemical properties are stable.
Non-combustible, low odor, low toxicity.
