Bumwe mu buryo bworoshye bwo gukora ikizamini cya flame ni ugukata icyitegererezo muri plastiki ukagitwika mu kabati ka fume. Ibara ryumuriro, impumuro nibiranga gutwika birashobora gutanga kwerekana ubwoko bwa plastike: 1. Polyethylene (PE) - Ibitonyanga, impumuro nka buji ; 2.Polypropilene (PP) - Ibitonyanga, impumuro nziza yamavuta ya moteri yanduye hamwe ninshingano. ya buji ; 3. Polymethylmethacrylate (PMMA, “Perspex”) - Ibibyimba, ibisasu, impumuro nziza ya aromatic ; 4. Polyamide cyangwa “Nylon” (PA) - Umuriro wa Sooty, impumuro ya marigolds ; 5. Acrylonitrilebutadienestyrene (ABS) - Ntabwo ari mucyo, urumuri rwa sooty, impumuro ya marigolds ; 6. Polyethylene ifuro (PE) - Ibitonyanga, impumuro ya buji
