Note: The above technical standards come from the national standard of green PTFE tape for thread sealing. The standard number: QB/T 4008 20 10 can be replied in such detail. I believe the landlord knows what this product is and where to sell it.
Special note: the color difference of color raw material belt.
Red raw material belt: the density is 0.4G/CM3, which is used to seal fire hot water pipes.
Yellow raw material belt: density of 0.4G/ CM3, used for gas pipeline sealing.
Blue raw material belt: density 0.4G/ CM3, used for pneumatic and hydraulic.
White material belt: suitable for sealing all kinds of threads.
