Rubber and plastic products - what are the main applications of TAIC?
1. Plastic TAIC can improve the heat resistance, chemical stability and thermosetting properties of CPE, PE, PA, PBT, PVC and other plastic materials.
2. Rubber TAIC can provide a low compression set and improved thermal aging performance for a variety of synthetic rubbers (such as EPDM, HNBR, TPE, FKM, EVA).
3. The combination of photovoltaic TAIC and peroxide can improve the curing speed, improve production efficiency, save production costs, and enhance the efficiency / efficiency of solar modules by improving the transparency of EVA sealing materials.
Note: in order to obtain the necessary structural stability, EVA coating has to be crosslinked by peroxide during the lamination process. By using TAIC as a crosslinking additive in EVA coating, the crosslinking process is significantly improved, resulting in the following advantages / advantages:
A. Curing time reduction / cost savings
B. Increase of glue content / crosslinking degree
C. Increased transparency
D. Improved color stability by shorter curing time
