PET (polyester) heat shrink tubing is non-toxic and environmentally friendly, harmless to people and the environment. It is SGS tested and meets Sony SS-00259. Its mechanical strength, high-temperature resistance and electrical insulation far exceed PVC heat shrink tubing, yet it is applied in exactly the same way, so no new equipment is required. It is the next-generation replacement for PVC tubing and the preferred choice for exporters of batteries and electrolytic capacitors.
Features:
★ Halogen-free, low smoke; complies with RoHS, REACH and Sony environmental standards;
★ Ultra-thin, non-toxic, harmless to people and the environment.
PET tubing colours: TA-1 black, TB-1 dark blue, TC-1 violet blue, TC-2 translucent blue, TD-1 brown, TE-1 red, TF-1 orange, TG-1 yellow, TG-2 translucent gold, TH-1 light green, TH-19 apple green, TH-8 dark green, TI-1 light purple, TJ-1 sky blue, TK-1 grey, TL-1 white, TL-2 clear
Applications: an ideal encapsulation for electrolytic capacitors, inductors and other components, premium rechargeable batteries, toys and medical devices; meets export requirements.
