Main function
|
|
Jointing compound
|
1.Improves the workability
2.Reduces cracking in the finished product
|
|
Coating
|
1.Keep suspension
2.Reduce chalking, shrinking, and shearing of the finished surface
3.Reduce water penetration and weathering
4.Brighten the tone
5.Produce a pearlescent luster
|
|
Plastics
|
1.Improve insulativity and fire resistance
2.Improve tensile strength and bending modulus
3.Improve size stability, reduce shrinkage, warpage and tortuosity
4.Make smoother surface and Improve optical performance
|
|
Rubber
|
1.Enhance the strength and toughness
2.Improve anti-cracking,anti-aging and anti-corrosion performance
3.Improve insulativity and fire resistance
4.Resistant to acid and alkali
5.Improve dielectric property
|
|
Asphalt roofing
|
1.Act as an antistick agent
2.Do not absorb the asphalt and stands up well to weathering
|
|
Drilling mud
|
Help to seal porous sections of the drill hole to reduce circulation loss
