Chemical Name: Amorphous Silica

Product Name: Topfine N98



Topfine N98 is an amorphous (non-crystalline) silicon dioxide consisting of perfectly spherical primary particles (150 nm mean dia). It is inert, non-toxic and eco-friendly. It will not decompose even in a fire.

TOPFINE N98 is readily dispersed in, and compatible to most thermoplastics elastomers and WPC.



Flame retardancy: TOPFINEN98 is a flame retardant synergist that improves the char strength and makes the flame retardant additives (ATH, MDH, ATO, APP, etc) work more efficiently, allowing a reduction in the addition level of the flame retardants. It can replace 30% ATO without flame retardent effect changing.

Rheology: TOPFINEN98 acts like sub-micron ball bearings, reducing the torque in mixing (saving energy and may allow a higher filler loading). It can reduce the buildup of plate out by lowering the friction against the tooling in an extruder (better and a more uniform flow and better surface). The ball bearing effect also helps to disperse inorganic fillers and additives, making the compounds more homogenous.

Dynamic fatigue: TOPFINEN98 shows excellent fatigue resistance, brings longer service life, brings lower risk of failure, increasing more than 50% property of fatigueresistance.
