Application features

ZCGJ-KL68L is a polymeric epoxy functional chain extender agentThe epoxy functional group in its structure can extender the polymer chain by reaction with the terminal hydroxyl, carboxyl and amino groups in the resin, to improve the resin characteristic viscosity, mechanical properties and inhibit polymer hydrolysis.

it can be used for food contact materials.

ZCGJ-KL68L usually are blended with modified resins by a double screw extruder, single screw extruder. The recommended dosage is 0.2-1.5phr used in bio-based and biodegradable plastics (such as PLA, PPC, PBS, PHA, etc.) and 0.2-2.0phr 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

 

Sanitation & Safety

Oral acute toxicity of ZCGJ-KL68L in mice: LD50 (lethal dose 50) values were more than 5000mg/kg for male and female mice.  It should be avoided to form dust in the course of operation and use. Keep away from the fire source.

Packaging

Carton  lined with plastic bags.

Storage

Should be stored under light avoidance, low temperature, dry, sealing conditions.
