Test purposes: To explore the flame-retardant effect of PEGL04 flame-retardant masterbatch in different applications and added amounts;
Test method: UL94 combustion test method;
Test Results:
Test 1: Spline extinguishes for 23 seconds from the fire;
Test 2: The first time the expulsion from the fire extinguished 1-2 seconds, the second extinction from the fire 4-6 seconds;
Test 3: The splines are extinguished from the fire for the first time and extinguished from the fire the second time.
Test 4: The spline extinguishes 1-2 seconds away from the fire;
Test 5: The first extinguishing of the splines from the fire; the second extinguishing from the fire;
Test 6: The spline extinguishes for 10 seconds from the fire;
Test 7: The spline is extinguished for the first time from the fire, extinguished for the second 2-3 seconds;
Test 8: The first extinguishment of the spokes from the fire, the second 3-4 seconds off;
Test IX: The spline is not extinguished from the fire;
Test 10: 1.6mm thick strips and 0.8mm thick strips, once extinguished from the fire, extinct from the second extinction;
Test XI: The spline is not extinguished and the lighter test is extinguished in 8-9 seconds;
Test Twelve: The spline extinguishes from the fire;
Test Thirteen: The spline extinguished 3-5 seconds away from the fire;
Test 14: The spline extinguishes within 2 seconds of leaving the fire, extinguishing the fire-fighting seedlings, and dropping a large drop;
Test fifteen: The spline extinguishes for 3-5 seconds from the fire. The flame is small and drops quickly.
Test XVI: The splines are extinguished and do not affect performance;
friendly reminder
1, PEGL04 flame retardant masterbatch, used for blown film and cast film, added 12%, extinguished 2-3 seconds away from the fire; add 15%, away from the fire.
2, calcium carbonate will affect the flame retardant PEGL04, it is best not to add, including the masterbatch also do not contain.
3, HPP flame retardant masterbatch and XPP flame retardant masterbatch, are our company's two masterbatch for PP flame retardant, detailed introduction to our company's PP flame retardant masterbatch instructions.
4, the above data is for reference only, due to different products, different equipment, different formulations, different raw material brands and other factors, the added amount of flame retardant masterbatch will be different, the use of masterbatch must be done before debugging, normal Mass production.
Final conclusion of the experiment
PEGL04 flame retardant masterbatch is widely used in LLDPE, LDPE, HDPE and other pure PE bellows, drawing, blown film, cast film, plate and other products, but also suitable for composite PE, PP coextruded pipe, plate and so on.
