Exolit® RP 607

• Mostly inert against atmospheric influences due to the combination of stabilization and microencapsulation. High oxidation and thermal stability because of a unique stabilization
• Can be used in a large number of plastics alone or in combination with nitrogen- or halogen-containing flame-retardants
• Insoluble in water and organic solvents
• Particularly effective when used with condensation polymers such as polyamides, polyesters, polyurethanes, polyisocyanurates and epoxy resins
• For polyolefins and polystyrene we recommend the combination with synergists
• Can be used for solid plastics, closed cell foams, polymer adhesives at processing temperatures up to 300°C
• Non-halogenated flame retardant with favorable environmental and health profile

• Exolit RP 607 can be used alone or with nitrogen- or halogen-containing flame retardants in a wide range of plastics.
• Particularly effective in condensation polymers such as polyamides, polyesters, polyurethanes, polyisocyanurates, and epoxy resins.
• For polyolefins and polystyrene, synergists are recommended.
• It is essential to conduct tests with graduated quantities to determine the optimum concentration of Exolit RP 607 for each case.
• The best results are typically achieved with an addition of 2% to 10%, depending on the plastic type.
• Suitable for use in solid plastics, closed-cell foams, and polymer adhesives at processing temperatures up to 300 °C.
• The inherent red-brown color of Exolit RP 607 is transferred to any translucent and/or light-colored product it is added to.

• The product reacts explosively with oxidizing agents.
• During decomposition or combustion, yellow phosphorus and/or phosphorus pentoxide are formed.
• When processing is carried out, particularly at elevated temperatures, small amounts of phosphine may be formed, especially in the presence of water.
• As phosphine is a toxic gas, an effective extraction facility must be provided.
• Exolit RP 607 containers must be closed tightly whenever any of the content is removed.
• All handling operations must be carried out with due care, using only tools made from soft material (plastic, wood, etc.).
• Do not cut the metal bag closure or the bag itself.
• If fire breaks out, the most suitable extinguishing agents are water spray, foam, wet sand, and fire blankets.
• Fire extinguishers that operate under gas pressure are not suitable because they tend to whip up the red phosphorus powder and thus cause the fire to spread.
• Areas where fires involving red phosphorus powder have been extinguished should be doused several times with 2% potassium permanganate or with 10% soda or copper sulfate solution to render harmless the toxic and spontaneously flammable yellow phosphorus formed during the fire.
• Any mechanical movement of Exolit RP 607 as well as all operations in which Exolit RP 607 is exposed to intense heat, pressure, etc. should be carried out in an inert gas atmosphere (nitrogen or argon).

Minimum shelf life is 12 months from the date of shipping when stored according to the said conditions.
