4，Special reminder and extension test

1. The carrier of this flame retardant masterbatch is chlorinated polyethylene (CPE), and the processing temperature should be kept within the appropriate range during processing, and the residence time of the material in the screw should be minimized to avoid material degradation.

2, LLDPE1802 (88%) : PSM8002 (12%), 3.2mm, 2.0mm, 1.6mm flame retardant 1 -2 seconds extinguish.

3, LDPE2426H (90%) : PSM8002 (10%), 3.2mm, 2.0mm, 1.6mm flame retardant 1 -2 seconds extinguish.

4, HDPE5000S (85%) : PSM8002 (15%), 3.2mm, 2.0mm, 1.6mm flame retardant 1 -2 seconds extinguish.

The above experimental test typical data and injection data are for reference only, not as a formal warranty certificate.

PS flame retardant masterbatch decomposition temperature ≥ 285℃, non-corrosive, will not produce damage to the twin-screw, easy to mix in the PS processing process, has a certain effect of smoke suppression, in the PS processing process of the plate, can reduce the density, enhance the strength of the plate.PS flame retardant masterbatch can also enhance the viscosity of the material and foam multiplier, to enhance the mechanical and physical properties.
