Our Exolit® RP line of flame retardants
safer fire safety based on red phosphorus

Roll out the red carpet for our halogen-free and safe-to-handle solutions

Red phosphorus makes matches ignite – and, due to the pure elemental activity obtained, is also one of most powerful flame retardants known. We offer this powerful non-halogenated additive in various stabilized, safe-to-handle forms that can provide potent fire safety to polymers and specialty coatings.

Protecting people and products at every stage

Like coated pills, our Exolit® RP flame retardants are stabilized and microencapsulated so they can be more safely and easily »administered« to polymer systems. While this reduces the hazards associated with handling red phosphorus powders, even relatively small additions can significantly increase product fire safety allowing to meet the most stringent standards.

Exolit® RP is available as a highly stable dry powder particularly suited for condensation polymers like polyamides, polyesters and polyurethanes, and also as wet press cake for latex systems. In addition, we offer grades in epoxy and polyol carriers for easier use in epoxy resins and PURs.

High phosphorus power, low hazards,
key benefits of our EXOLIT® RP line

1.

Potent flame retardants based on red phosphorus and available in different delivery forms: dry powder, wet press cake, or in an epoxy or polyol carrier

2.

Unique combination of chemical stabilization and microencapsulation for increased handling and processing safety

3.

Halogen-free, environmentally friendlier products with very high phosphorus content and efficiency for P-based flame retardants

What makes our Exolit® RP flame retardants so special? Florian Clausen has the answer

»We’ve found a way to offer our customers all the benefits of red phosphorus with practically none of the drawbacks. Using it for powerful polymer protection is now much safer and easier, and so is the incorporation into epoxies and polyurethanes.«

Exolit® RP 6500

Exolit RP 6500 is a brown-red paste, and is a blend of stabilized, micro encapsulated red phosphorus in an epoxy resin carrier. The paste form allows safe and simple handling of the red phosphorus in a liquid form, and avoids the hazards associated when working with red phosphorus powders. The thixotropic nature of this concentrate hinders the sedimentation process and simplifies the re-homogenization after long storage periods. For better handling, in particular regarding flow properties, the product may be warmed up to 50°C - max. 80°C.

Exolit® RP 6520

Exolit RP 6520, is a brown-red paste, and is a thixotropic blend of castor oil with stabilized, microencapsulated red phosphorus. The paste form allows safe and simple handling and thus processing is made easier. The thixotropic nature of this concentrate hinders the sedimentation process and simplifies the re-homogenization after long storage periods.

Exolit® RP 614 presscake

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.
