  • Scratch-resistance Composite
Characteristics
Technology
1Adopt specialized inorganic Filler M/B
· Adopt of Soft-PP M/B, PP -> Add self-healing of scratch and soft touch
· Composed of specialized inorganic filler -> Increase the heat-resistance
· PP/Rubber nano alloy form structured domain of nano~scaled formation in PP matrix is revealed
Technology
Adoption of Silicone rubber
· Adopt the silicone rubber, based PP/rubber nano-alloy
· Develop the scratch-resistance by decrease the coefficient of friction because of properties of silicone
· Take advantage of elastic-recovery of silicone rubber to increase self-healing about scratch and softness
Technology
3 Adoption of Silicone-G-grafted polymer
· Compare the touchness, heat-resistance, impact strength, scrath-resistance among the
PP/inorganic particle compound ->select to inorganic particle
· Total balance of properties which is hardness, self-healing, scratch and heat resistance
keeped by adding silicone-G-grafted polymer
