"Green Transition + Cyclical Reversal" Driving High-Quality Development In May 2026, China's coatings, plastics, and chemicals sectors showed positive momentum under the dual influence of policy guidance and market opportunities. Water-based coatings are accelerating substitution, the engineering plastics market has surpassed RMB 196 billion, and the chemical industry is emerging from a four-year downturn into a recovery phase — becoming this week's market focus.

As the world’s premier exhibition for the rubber and plastics industry, this grand event is themed “Innovation · Collaboration · Shaping Sustainability.” It serves as a global hub for innovative elements, comprehensively showcasing cutting-edge technologies and deeply interpreting the industry’s groundbreaking breakthroughs. Leveraging Shanghai’s unique industrial foundation and exceptional location, the exhibition will build an efficient bridge of cooperation, connecting buyers and exhibitors from around the world.

Thermogravimetric Analysis (TGA) is an analytical technique that measures the change in a substance's mass as a function of temperature or time under a controlled program. This method detects physical phenomena (such as melting, sublimation, and adsorption) and chemical reactions (including dehydration, decomposition, oxidation, and reduction) by recording mass loss events on a Thermogravimetric (TG) curve. On this curve, mass is plotted on the vertical axis (decreasing downwards) against temperature or time on the horizontal axis. TGA instruments typically consist of a precision balance, a furnace, a temperature control system, and a data recorder. The core measurement mechanisms rely on either the deflection method, which records beam inclination directly, or the null-point method, which uses an electromagnetic coil to counterbalance mass changes, converting the required restoring current into a precise mass-loss profile.

The Rubber Carbon Black Dispersion Tester is a specialized instrument designed in accordance with standard GB-6030 and international standard ISO-11345. Its testing principle is as follows: When rubber (vulcanized rubber or masterbatch) is cut, the undispersed carbon black aggregates, which possess higher hardness relative to the surrounding rubber matrix, cause deviations in the cutting path. This results in a rough and uneven cut surface. Furthermore, the larger the undispersed carbon black aggregates, the greater the surface roughness. Light is projected onto the cut surface at a specific angle. The surface conditions are magnified, directly displayed on the screen, and recorded as digital images. These digital images are processed by a computer. Based on the size and frequency of the protruding clusters on the cut surface, the system automatically evaluates the dispersion rating (Automatic Grading Function) in accordance with relevant standards to characterize the degree of carbon black dispersion in the rubber. Alternatively, the images can be directly compared with standard images stored in the instrument or with user-defined standards (Image Comparison Function).
