Silicon dioxide Nanoparticles(VK-SP30S) can improve the capabilities of materials for its strong electric property. silicon dioxide nanoparticles(VK-SP30S) is to treat nanometer silicon dioxide (resin) with resin acceptor special technology, so that it has good dispersion. silicon dioxide nanoparticles(resin) can improve the tensile strength, impact strength, breaking extension rate, stability of resin and keep its transparency.
The application of silicon dioxide nanoparticles (VK-SP30S) in resin:
1. Heat resistance: silicon dioxide nanoparticles(VK-SP30S) can adhere to the resin interface and absorb lots of strike energy because of its big surface volume. So nanometer silicon dioxide (VK-SP30S) can improve the intension, toughness and heat resistance of resin evidently.
2. Intension and toughness: silicon dioxide nanoparticles(resin) can greatly improve the tensile strength, impact strength, breaking extension rate, stability of resin.

Dosage:
The dosage of resin andsilicon dioxide nanoparticles(VK-SP30S) by weight is 100:5.Customers can adjust their dosage according to their systems.
Method of dispersion:
Nanometer particles are easy to reunite for their extra small size and big surface volume, so that it can not improve the intension and toughness of polymer effectively. For this reason, the nanometer particles should be dispersed well when we produce nanometer compound material. Treatment, such as mill, cutting with high speed, ball-grind, ultrasonic etc. can help nanometer particles to disperse evenly in resin.
We can also add some resin acceptor to improve the dispersion of nanometer silicon dioxide in resin. The rate of them is 5:100.
