as they should be added 3-4 minutes later after coupling agent’s activation modification to powder.
In the above methods, the former has the better effect.
Consumption:
1. For normal filler, 0.8-1.0% of filler
2. For thin film master batch, 1.5-2.0% of filler
3. For powder material, 1.0-1.5% of powder
4. For color matrix, cable material,1.5-3.0% of filler
5. For PVC products, 1.0-1.5% of filler
6. For hard PVC products, 0.5-1.0%
7. For coatings and inks, 0.7-1.5%
Fifth, attention
1. For composite product which use granulous resin as material, like PE, PP, ABC and PC, firstly make this product in
master batch or granules form, then mix with these resin;
2. Keep it away from water and fire and keep it dry. If sealed off, use it as soon as possible, or sealed again.
3. Used up within the best valid period (half year is recommended).
Sixth, packing
