Features Of Clariant Exolit OP935 Flame Retardant

  1. Halogen-free, phosphorus-based flame retardant offering excellent fire safety performance.

  2. Designed for high thermal stability and compatibility with polyamide 6 and polyamide 66 engineering plastics.

  3. Enables UL 94 V-0 rating at low loading levels (typically 10–15 wt%) in reinforced and unreinforced nylons.

  4. Maintains good mechanical properties—including tensile strength and impact resistance—after compounding.

  5. Low smoke and low toxicity profile, supporting compliance with stringent environmental and safety standards (e.g., RoHS, REACH).

Typical Applications Of Clariant Exolit OP935 Flame Retardant

  1. Electrical and electronic components requiring UL 94 V-0 certification, such as connectors and housings.

  2. Automotive under-hood parts including sensor housings, fuse boxes, and ignition system components.

  3. Industrial automation enclosures and control units exposed to elevated operating temperatures.

  4. Consumer electronics casings where flame retardancy and material aesthetics must be balanced.

  5. Power tools and appliance housings demanding reliable long-term thermal and fire performance.
