We have developed new heat shrinkable tubing products, "Sumitube HF2" and "Sumitube HF4," neither of which uses halogen or red phosphorus. These tubing products comply with the UL (Underwriters Laboratories, Inc.) 125°C rating and VW-1 flammability requirements. As environmental awareness increases, the electronics market has seen an increasing demand for halogen free heat shrinkable tubing. Likewise, red phosphorus free tubing is also desired in some cases.
