Exolit® RP 614

Exolit® RP 614 presscake is a fine brown-red powder with a water content of 10-25%, based on a highly stabilized, microencapsulated grade of red phosphorus. This allows a safe and simple handling of the red phosphorus in a presscake form, and avoids the hazards associated when working with dry red phosphorus powders. Exolit RP 614 Presscake is noted for its high oxidation and thermal stability. It is insoluble in water and organic solvents. Due to the combination of stabilization and microencapsulation, the material is mostly inert against atmospheric influences.

Product Benefits
  • Fine brownish-red powder based on a highly stabilized, microencapsulated grade of red phosphorus
  • Safe and simple handling: avoids the hazards associated to working with dry red phosphorus powders
  • High oxidation and thermal stability: mostly inert against atmospheric influences because of the combination of stabilization and microencapsulation
  • Insoluble in water and organic solvents
  • Very effective flame retardant due to its high phosphorus content
  • Can be used as a flame retardant for both synthetic and natural rubber latex systems
  • Used for a wide variety of water-based polymers, either alone or in combination with aluminium trihydroxide or other synergists
  • Non-halogenated flame retardant with favorable environmental and health profile

Applications & Uses

Compatible Polymers & Resins
Product Applications
  • Exolit RP 614 Presscake can be used to flame retard both synthetic and natural rubber latex systems.
  • Due to its high phosphorus content, the product is a very effective flame retardant for a wide variety of water-based polymers either alone or in combination with aluminium trihydrate or other synergists.
  • Since red phosphorus tends to emit small amounts of the toxic gas phosphine (PH3) – even if it is very well stabilised – we advise against using Exolit RP 614 Presscake for large area indoor applications like flame retarding mattresses or carpets.
  • The inherent red-brown colour of Exolit RP 614 Presscake is transferred to any product to which the flame retardant is added.

Safety & Health

Safety Information
  • Exolit RP 614 Presscake containers must be closed tightly whenever any of the content is removed.
  • Although the desensitising process greatly reduces the sensitivity of red phosphorus to impact and friction, as does the residual water, all handling operations must be carried out with due care, using only tools made from soft material (plastic, wood, etc.).
  • 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, 10% soda, or copper sulphate solution to render harmless the toxic and spontaneously flammable yellow phosphorus formed during the fire.
  • Any mechanical movement of Exolit RP 614 Presscake as well as all operations in which Exolit RP 614 Presscake is exposed to intense heat, pressure, etc. should be carried out in an inert gas atmosphere (nitrogen, argon).
