1. How to choose engineering plastic silicone masterbatch 20
1. Determine processing requirements: Firstly, clarify the specific requirements for engineering plastic processing, including processing techniques (such as injection molding, extrusion, blow molding, etc.), product performance requirements (such as wear resistance, flame retardancy, chemical resistance, etc.), and environmental factors (such as temperature, humidity, etc.).
2. * * Understand the characteristics of silicone masterbatch * *: Study the characteristics of different silicone masterbatch, including their chemical composition, molecular weight, siloxane content, carrier type (such as polyolefin, polyester, etc.), and whether they contain other additives (such as coupling agents, antioxidants, etc.).
3. * * Consider compatibility * *: Choose silicone additives with good compatibility with engineering plastic substrates to ensure uniform dispersion during processing and avoid material performance degradation caused by poor compatibility.
4. Evaluation of Processing Performance: Based on the requirements of the processing technology, select silicone additives that can improve melt flowability, reduce processing torque, enhance mold filling ability, and demolding performance.
5. * * Consider improving physical properties * *: If it is necessary to improve the physical properties of engineering plastics, such as wear resistance, glossiness, hardness, etc., choose silicone additives with corresponding functions.
6. * * Consider environmental and safety factors * *: Choose silicone masterbatch that meets environmental standards to ensure that it does not pose a threat to the environment or operators during use.
7. * * Conduct experiments * *: Prior to practical application, conduct small-scale experiments to evaluate the dispersibility, processability, and final product performance of the selected silicone masterbatch in specific engineering plastics.
8. Economic evaluation: Considering the cost-effectiveness of silicone additives, choose products with high cost-effectiveness while meeting processing and performance requirements.
9. Supplier evaluation: Select suppliers with good reputation and stable quality to ensure the supply continuity and quality consistency of silicone masterbatch.
