Tung Oil Tung Oil is a drying oil obtained by pressing the seed from the nut of the Tung tree. Tung oil hardens upon exposure to air (through polymerisation), and the resulting coating is transparent and has a deep, almost wet look. Used mostly for finishing / protecting wood, after numerous coats the finish can even look plastic-like. […]

Flame retardants corresponds to several substances which are added to combustible materials to prevent fires from starting or to slow the spread of fire and provide additional escape time. Among them, there exist TCPP and TEP.
TCPP (CAS : 13674-87-8)
TCPP Chemical Structure Composition.
Tris (1-chloro-2-propyl) phosphate is an PU foam’s additive used as flame retardant in consumer products, home insulation and electronics. The product is a colorless liquid stable at ambient temperature and not volatile. It’s obtained by a reaction of 1-chloro-2-propanol with phosphoryl chloride in the presence of a catalyst.
TEP (CAS : 78-40-0)
TEP Chemical Structure Composition.
Triethyl phosphate is not only used for PU foam. It can reduce also the viscosity of some polyols and prepolymers. TEP can be produced in 2 various ways : by reaction of phosphoryl chloride with ethanol or by oxidation of triethyl phosphite.
Flame retardants shows low acute toxicity following oral, dermal or inhalation exposures. It’s a slight skin and eye irritant and is not genetically active.
