Carbon Black N550

Carbon Black N550

Product Introduction
“LAILI” N550 has two species——one use to products of extrusion molding,other use to tire. Because of less impurity, 45 μm residuum on sieve less then 200ppm, It can improve the fineness of products of extrusion molding, reduce to change stranger of extruder, Increase the life of extruder stranger, delay the die abrasion. It has long scorching time and it can improve making safety,reduce the rubber products number of reject and seconds.

Product Application
Sealing, Water proof material, Rubber tube, Adhesive tape, Products of extrusion molding, etc.“LAILI" N550 is a kind of carbon black high structure low specific surface area. It has better dispersiveness than N330 and better strength and viscosity than N660. And it is more pure than other carbon black.
