Exolit™ OP 935 Terra ISCCplus
Exolit OP 935 Terra ISCCplus is chemicially and from its composition equivalent to Exolit OP 935, but comes with a mass balance certificate as for its production, renewable based Ethylene was sourced. Therefore we assume that for Exolit OP Terra ISCCplus products no additional performance testing and qualification compared to the standard grade are necessary.
Exolit OP 935 Terra ISCCplus is a white, fine-grained powder based on an organic phosphinate. The product is not hygroscopic and it is insoluble in water and common organic solvents like acetone, dichloromethane, MEK, toluene. Exolit OP 935 Terra ISCCplus can easily be dispersed in solvents like acetone or MEK.

Product Information
- Based on an organic metal phosphinate
- Not hygroscopic, insoluble in water and common organic solvents like acetone, dichloromethane, MEK, toluene
- Good hydrolysis resistance
- Can easily be dispersed in solvents like acetone or MEK
- Halogen-free flame retardant with a high phosphorus content which is suitable for use in both thermoplastic and thermoset applications to meet the most stringent fire retardancy standards
- Suited for thermoplastic elastomers for cable applications
- Particularly suitable for very thin adhesive applications like flexible printed circuit boards due to its specifically designed particle size distribution; can be readily dispersed in epoxy resin systems when a high shear mixer is used
- Low smoke toxicity
- Non-halogenated flame retardant with favorable environmental and health profile
Hazards
The product does not require a hazard warning label according CLP regulation (Regulation (EC) No. 1272/2008, as amended).
