Filler Flame Retardant L series
Compatibility is good, has good viscosity, can be used as reinforcement, enhancement filler.
It can partially replace carbon black and white carbon black.
Suitable for foaming, it has better foaming ratio, excellent foaming uniformity, and can improve the dimensional stability of the product.
It can improve the strength, whiteness and cable insulation of film products, cables, construction,CCL (for PCB) and PVC products.
It has the effect of improving the scattering transmittance in the plastic film and blocking infrared rays.
