Polycarbonate, a linear polymer containing carbonic acid groups in the molecular chain. As a high-end petrochemical product, PC is the fastest growing thermoplastic material in the five major engineering plastics, with excellent overall performance in electronic appliances, sheet containers, and automobiles. Industry, medical equipment, protective equipment and other fields have been widely used, and quickly expanded to aerospace, optical components, optoelectronic information and other emerging areas.
After more than ten years of independent research and development by Wanhua Chemical, a 70,000-ton/year interface phosgene PC device has been successfully put into production, bringing high-quality CLARNATE® PC products to customers. Among them, the 2100 grade is designed for the modification market. A powdered PC product. Compared to traditional pellet PCs, it will bring you a brand new application experience and achieve unexpected results.
Improve product quality
Wanhua Chemical's new-generation modified PC powder adopts a new multi-level low-temperature devolatilization process. The entire production process is completely free of high-temperature heating, and the initial performance of the product is kept to the maximum.
A variety of low-level powder functional additives are used in the modification process. The powder system not only has a good mixing effect, but also can significantly reduce the measurement error and improve the product stability if the premixed process is adopted.
Expand design freedom
In formula design, on the one hand, because no additives are added to the powder PC, the degree of interaction between different raw materials is reduced; on the other hand, premixing with any ratio of functional additives can be realized, and the design boundary of the formula is extended. .
Reduce device costs
Due to the improvement in mixing and metering, the investment cost of the new reforming device can be significantly reduced, and the more complicated the formula is, the higher the quality requirement is, the more significant the system cost reduction is.
Wanhua Chemical PC powder products not only have the above advantages, but also break through two process difficulties through independent research and development:
1. Obtain excellent particle size distribution while maintaining high bulk density;
2. Control the low residue of volatiles at lower temperatures.
Avoid the use of PC powder products in the production process may produce dust and exhaust.
Relying on 10,000-ton PC devices, Wanhua Chemical will continue to launch a series of innovative PC products for you. Stay tuned!
