Thermoplastics and thermosetting plastics represent two fundamental categories of polymers with distinct molecular structures and behaviors. Thermoplastics possess a linear or branched molecular structure. This allows them to soften and melt when heated, enabling them to be shaped and molded. Upon cooling, they solidify and retain their new form. A key advantage of thermoplastics is […]

Polycarbonate (PC) plastic is renowned for its high performance but has a significant affinity for moisture, leading to a high water absorption rate. Therefore, a crucial pre-processing step is mandatory: preheating and drying. The specific drying parameters depend on the material type; pure PC typically requires drying at 120°C, while modified PC grades are generally

The application scope of polymer materials continues to expand, particularly in electronics, household appliances, and many other sectors. This growth has driven the widespread use of flame-retardant materials for manufacturing components, meeting the rising global demand for enhanced product safety and compliance with stringent fire safety regulations. KEYUAN’s comprehensive portfolio of flame-retardant and flame-retardant enhanced

Glass Fiber Reinforced Polypropylene (GFPP): The addition of glass fibers significantly enhances the mechanical properties, thermal stability, creep resistance, and dimensional accuracy of standard polypropylene. This makes GFPP an ideal material for demanding applications such as fan blades, battery casings, heater housings, washing machine pulleys, filter plates and frames, various industrial pipes, and a wide

Exceptional chemical stability and corrosion resistance Cost-effective manufacturing and versatile applications Durability, water resistance, and favorable strength-to-weight ratio Excellent processability and mass production capabilities Superior electrical insulation and thermal resistance Aesthetic versatility with gloss, transparency, and color options Potential for fuel recovery through pyrolysis

PVC/ABS Alloys: Start with pure ABS and adjust additives based on required toughness Recycled Flame-Rardant ABS: Supplement with additional toughening agents and flame retardants as needed, processing at reduced temperatures Toughened ABS: Incorporate high-rubber powders, EVA, or other elastomers High-Gloss ABS: Blend with PMMA, PC, AS, or PBT with appropriate additives Fiber-Reinforced ABS: Avoid simple

Degradable plastics include photodegradable, disintegratable, and biodegradable types. Photodegradable and disintegratable plastics are made from conventional plastics and do not fully decompose. Biodegradable plastics are produced from biomass resources (e.g., plant fibers, starch) and can completely break down. Raw materials for biodegradable plastics include PLA, PHA, PGA, PBS, PBAT, and PCL. Common products are tableware,

The use of natural resins like asphalt, rosin, amber, and shellac dates back to the 19th century. In 1868, celluloid—the first plastic—was made from cellulose nitrate and camphor. The first synthetic plastic, phenolic resin, was introduced in 1909, followed by amino plastics in 1920, both vital to the electrical and instrument industries. The 1920s–1930s saw

The ABS and PS markets are currently experiencing significant price increases driven by multiple market forces. International crude oil price fluctuations and upward movements in upstream monomer costs have created a market environment characterized by heightened speculative activity and excited trading behavior. Market participants demonstrate reduced willingness to offer materials at lower prices, maintaining an

Polycarbonate (PC) stands as one of the five primary engineering materials, valued for its colorless transparency, heat resistance, impact resistance, and excellent mechanical properties. Its superior processability has led to widespread application in everyday products including lenses, containers, and optical discs. However, conventional PC materials often fall short in meeting industrial flame retardancy requirements, necessitating
