Polyethylene oxide in a non-toxic long-chain polymer with a high molar mass. Because of extensive hydrogen bonding it is soluble in water. A solution of Polyox (approximately 1% w/v) behaves as an 'elastic liquid' i.e. it 'self-siphons'.If you quickly drag some of the solution from a beaker with a spatula or spoon it will continue to move out of the beaker. You can even draw it up into a syringe even though the tip of the syringe is above the liquid level.(5g is sufficient to make about 500 cubic cm of the fluid).Supplied in 50g pack.Bulk orders will be supplied in a single bag.Please note: Propan-2-ol (B8F78836) is required for use with this item.
