Sri Vasavi Pigments ANTIBLOCK MB 01(SV 91A001AB)

Layers of plastic films have a tendency to stick together (BLOCK), making it difficult to separate film layers, especially LDPE, LLDPE, HMHDPE, PP, EVA Films. Antiblock Masterbatches are added during manufacturing of films and bags to separate both layers easily (prevent sticking together). They are useful to decrease the adhesion between films and surfaces of other objects. These Masterbatches act by producing a slight roughening of the surface, thus allowing easy opening of films. Many types of Anti Block additives are available, ranging from synthetic silica for high clarity, through natural silica to offer high performance where cost is important and clarity can be compromised, to talc where simple anti-blocking properties without clarity are required. Antiblock masterbatches can be produced in a wide range of polymers including polyethylene, polypropylene, ionomers, polyamides, thermoplastics, polyurethanes and others. Combinations with Antiblock and slip additive offer cost effective products for use in the film industry. Antiblock agents are mainly used in film extrusion. We use both synthetic amorphous precipitated silica and natural silica depending on end use products. Silica is fine white odorless powder, chemically inert, non-toxic and free from impurity.
