Translink 37 is a high performance reinforcing extender designed to reduce water transmission in polymer systems when used in electrical applications. The reduction in residue reduces the adverse effect that residue has on electrical insulative properties as well as extrusion processability. Translink 37 provides excellent initial and aged wet electrical properties. It is recommended for use with peroxide cure systems. Translink 37 kaolin provides excellent barrier properties against moisture penetration. Its unique surface treatment makes it highly compatible with various polymer matrices used in applications. The product enhances mechanical strength, thermal stability and durability of finished products. It can be used as a reinforcing filler and extender to improve physical properties without compromising optical characteristics.
