I posted some of this information in another thread, but thought I would dedicate a thread showing the difference between how silicone vs nitrile rubber burns. The tables below show the key differences when the rubber is burned. If you have a doubt on if the ADBV is silicone or nitrile (ie, a claimed "black silicone" ADBV), then try setting it on fire - outside of course.
This is a simple test to verify if a filter ADBV is silicone or nitrile rubber. Some companies claim that their black ADBV is silicone ... is it really ??
Regardless of the color of the ADBV, it will burn as shown depending on if it's silicone or nitrile. The differences are quite evident. Both ADBVs where thoroughly cleaned with 99% isopropyl alcohol before burning.
SILICONE ADBV
This is a burn test on a Fram Ultra silicone ADBV. It burned just like the tables above indicate. I could hardly get it to start on fire (had to hold the lighter on it for a very long time), and the flame would barely burn and self extinguish. Hardly any smoke, and the burned rubber was white ash. The burned rubber just flaked off after the flame self extinguished.
NITRILE ADBV
This is a black shiny ADBV from a quick lube oil filter - looked like a Champ Labs made filter. Did the burn test and it's 100% obvious that it is nitrile.
Started on fire almost instantly and easily, and the flame spread quickly, and gave off lots of black smoke. No white burn residue, but instead a black burn residue. Definatly smelled much more like "burnt rubber" than the silicone ADBV.
Some people may think the shiny black ADBVs are silicone, but this test shows otherwise.
