Chain Extender Kl E4370 - China

Chemical Names:

Styrene (ST), methyl methacrylate (MMA) and methyl methacrylate (GMA) copolymer English Name :

2-Propenoic acid, 2-methyl-, oxiranylmethyl ester, methyl methacrylate, polymer with ethenylbenzene Formula : (C21H28O5)n

Molecular Weight : 6500-7200

CAS No : 1191261-43-4

Application Features

KL-E4370 is an polymeric epoxy functional chain extender.

In its structure, the epoxy functional group can realize the expansion chain of the polymer through reacting with the terminal hydroxyl groups, terminal carboxyl groups and terminal amino groups of polycondensation resin.

Thus achieving the purpose of improving polycondensation resin viscosity characteristics, mechanical properties and inhibiting the hydrolysis of polymers.

KL-E4370 chain extenders are blended with modified resins by a double screw extruder, single screw extruder.

The recommended dosage is 0.2-1.5 % used in bio-based and biodegradable plastics (such as PLA, PPC, PBS, PHA, etc.

) and 0.2-2.0% used in the condensation recycled plastics (such as PET, PBT, PC, PA, etc.

).

The specific amount depends on the number of active functional groups and performance requirements of products.
