China C5 hydrogenated petroleum resin, also known as C5 hydrogenated petroleum resin, is an important standard for measuring its quality and performance. The following is a detailed introduction to the main product indicators of C5 hydrogenated petroleum resin:
1. Key performance indicators
1. Softening point
The softening point is the temperature at which a resin begins to flow when softened by heat, and is an important indicator for measuring the thermal stability and processing performance of the resin. The softening point of China C5 hydrogenated petroleum resin is usually between 90 ℃ and 120 ℃, and the softening point may vary among different models of products. For example, some high-end models of resins may have a higher softening point, making them suitable for applications that require higher heat resistance.
2. Hue (Gardner color scheme)
Hue is an indicator for measuring the color of resin, usually represented by Gardner chromaticity. The color of C5 hydrogenated petroleum resin should be low to ensure the appearance quality and transparency of the product. Generally speaking, the hue value (Gardner color) should be less than or equal to a certain value (such as 35.0max), depending on the application requirements of the product and industry standards.
3. Ash content
Ash content is the inorganic substance remaining after high-temperature burning of resin, which is an indicator of resin purity. The ash content of China C5 hydrogenated petroleum resin should be low to ensure the quality and performance of the product. Generally speaking, the ash content (measured as a volume percentage) should be less than or equal to 0.02%.
4. Melt viscosity
Melt viscosity is an indicator of the flowability of resin in a molten state. The melt viscosity has a significant impact on the processing performance of the resin and the performance of the final product. The melt viscosity of China C5 hydrogenated petroleum resin is moderate, which is beneficial for its flow and molding during processing.
5. Thermal stability
Thermal stability is the ability of a resin to maintain stable performance in high temperature environments. For products that need to be used in high-temperature environments (such as hot melt adhesives, hot-melt road marking paints, etc.), thermal stability is a crucial indicator. Carbon five hydrogenated petroleum resin has good thermal stability and can maintain stable performance in high temperature environments.
2. Other indicators
In addition to the key performance indicators mentioned above, China C5 hydrogenated petroleum resin may also involve other indicators such as acid value, bromine value, n-heptane capacity, etc. The specific values and importance of these indicators depend on the application requirements of the product and industry standards.
In summary, the product indicators of China C5 hydrogenated petroleum resin cover basic physical properties, key performance indicators, and other possible indicators. These indicators collectively constitute important standards for measuring the quality and performance of C5 hydrogenated petroleum resins.
