What plastic is PP · S Polyphenylene sulfide?

What plastic is PP · S Polyphenylene sulfide?

Summary Description:PP · S is one of the engineering plastics with good heat resistance. Its Chinese name is Polyphenylene sulfide, which is a new high-performance thermoplastic resin. The molecular structure is symmetrical, easy to crystallize, and nonpolar.
PP · S is a special engineering plastic with excellent comprehensive performance, which has excellent high-temperature resistance, corrosion resistance, radiation resistance, flame retardancy, balanced physical and mechanical properties, excellent dimensional stability, and excellent electrical properties. It is widely used as a structural polymer material and is widely used as a special engineering plastic after filling and modification. At the same time, various functional films, coatings, and composite materials can also be made, which have been successfully applied in fields such as electronics, aerospace, and automotive transportation.
The thermal deformation temperature of PP · S is generally greater than 260 degrees, with chemical resistance second only to polytetrafluoroethylene and flowability second only to nylon. It has advantages such as low shrinkage, low water absorption, good fire resistance, and good resistance to vibration fatigue.
PP · S is mostly used as a modified variety, specifically through glass fiber reinforcement, glass mineral fiber reinforcement, carbon fiber reinforcement, etc.

Main performance requirements for pigments used in plastic masterbatches

TIme:2023-06--28
1. Coloring power The coloring power of a pigment refers to the amount of pigment required for a certain color product, expressed as a percentage of the coloring power of a standard sample. The coloring power of a pigment is not only related to its properties, but also to its degree of dispersion. The degree of dispersion mainly refers to the degree of refinement of the pigment. The greater the degree of dispersion, the stronger its coloring power, but it has a saturation value. 2. Heat resistance Heat resistance refers to the degree of change in the color or performance of pigments under processing and usage temperatures. When considering the heat resistance of pigments, it is also important to consider their heating time. Due to the different processing methods and heating times of plastics when processed into products, and the different uses and heating times during use, the higher the temperature used, the shorter the heat resistance time. 3. Migration resistance The migration resistance of pigments refers to that the colored plastics may have physical and chemical reactions with the above substances when they are in long-term contact with other solid, liquid, gas and other substances or when they work in a specific environment, which is manifested by the migration of pigments from the inside of plastics to the Free surface of products, or to the adjacent plastics or solvents. 4. Light resistance and weather resistance Plastic products require good light and weather resistance due to long-term outdoor use. Some pigments undergo varying degrees of color changes under light exposure. Weathering resistance refers to the color stability of pigments under natural conditions. Due to its extensive outdoor use, the black mother pays special attention to migration resistance and weather resistance.
