2、 Main functions and uses
For surface activation and modification
At present, it mainly uses:
1. Surface modification of fillers for various PVC products.
2. Production of fillers for various polyolefin products (PE, PM, PP masterbatch).
3. Surface modification of fillers for rubber and various plastic products.
4. Rubber plastic blends.
5. Surface modification of various organic and inorganic fillers and pigments (light and heavy calcium carbonate, talcum powder, titanium dioxide, kaolin, clay, carbon black, paint, ink, flame retardant, adhesive, PVC, PE, PP, etc.).
3、 Usage and dosage
1. Pretreatment method: preheat the filler to 110-130 ° C in the high-speed mixer, remove the moisture, then put in the coupling agent, mix it at high speed for about 5 minutes, and then discharge it.
2. Direct addition method: if the water content of the filler is less than 0.5%, directly add coupling agent.
3. Reference dosage:
Application scope and dosage:
Aluminate coupling agent PVC filler: 0.5-1.3%.
