Features Of VIAPAL RAYLOK 1722 Flame Retardant

  1. Halogen-free phosphorus-based chemistry for low smoke and reduced toxic gas emission during combustion.

  2. Excellent thermal stability, maintaining performance up to 300 °C in polymer processing conditions.

  3. Good compatibility with polyolefins, engineering thermoplastics, and thermoplastic elastomers.

  4. Non-migrating formulation ensures long-term flame-retardant efficacy and surface integrity.

  5. RoHS and REACH compliant, supporting sustainable material design and regulatory readiness.

Typical Applications Of VIAPAL RAYLOK 1722 Flame Retardant

  1. Wire and cable insulation and jacketing for low-smoke zero-halogen (LSZH) applications.

  2. Flame-retarded polypropylene (PP) and polyethylene (PE) compounds for automotive interior components.

  3. Electrical enclosures and housings requiring UL 94 V-0 rating at 1.6 mm thickness.

  4. Thermoplastic elastomer (TPE) profiles used in public transport interiors and building fixtures.

  5. 3D printing filaments where fire safety and printability must be balanced.
