PET heat shrinkable tube aluminum electrolytic capacitors
This product has a long-term temperature resistance of - 40+125 ℃ and is mainly used for packaging, insulating, and labeling aluminum electrolytic capacitors, tantalum capacitors, farad capacitors, automotive starting capacitors, batteries, inductors, and other products
This product is 125℃ environment protecting plastic tube. It’s strong point is able to bear hot, cold, not easy to broken and hard to shrink again after first shrink. comply with the related hazardous substances control regulations, such as RoHS 2.0, Sony SS-00259, REACH SVHC and halogen-free etc. No crack happened after put it in oven 250℃ and remain for 30 seconds or put it in constant temperature and humidity machine -40℃ and remain for 60 minutes.
