  • This article explains the differences between mold temperature controllers (MTCs) and industrial chillers in plastic manufacturing. Both devices regulate temperature, but their principles and applications differ. MTCs provide precise heating and stable temperature control for molds, enhancing product quality and production efficiency in processes like injection molding, blow molding, and extrusion. Industrial chillers offer rapid cooling and constant-temperature water for equipment or materials that require heat removal. Understanding their working principles, control accuracy, and appropriate usage scenarios helps manufacturers optimize production, improve product quality, and reduce energy consumption.

  • This article introduces the six key properties of modified flame-retardant polypropylene (PP). It explains PP’s strong mechanical performance, excellent physical characteristics, high chemical stability, and reliable heat resistance with a melting point of 164–170°C. The material also offers improved weatherability and outstanding electrical insulation. Flame-retardant PP uses phosphorus–nitrogen halogen-free systems, achieving UL94 V-0 and meeting GWIT 750°C and GWFI 960°C tests. With low smoke, low density, and minimal mold corrosion, flame-retardant PP is widely used in electrical components, automotive parts, and various extruded or molded plastic applications.
