ProFlame ® ZHS
ProFlame-ZHS flame retardant synergist inhibits the development of flames and smoke, and is safe for human health and the environment. ProFlame-ZHS is a zinc hydroxystannate that has both a condensed phase and vapour phase action during the rapid degradation of polyvinyl chloride and polymer materials containing halogenated and antimony additives. In halogen-free flame retardant polymer materials it can act to increase the char consistency and strength.
ProFlame-ZHS is insoluble in water and releases 15w% of water starting at 220 °C. At higher temperatures (400 °C - 600 °C), zinc and tin ions can be volatilised or liberated from their structure to exert catalytic activity. ProFlame-ZHS is part of a family of n-type wide bandgap semiconductors with a high concentration of free electrons in the conduction band, thus leading to high optical transmissions in combination with electrical conductivity.
Chemical name: Zinc hydroxystannate CAS NO.: 12027-96-2
Molecular weight: 286.15 Chemical formula: ZnSnO3.3H2O or ZnSn(OH)6
Usage:
►ZHS can replace Molybdenum Trioxide in PVC FRLS cable compound
►ZHS was developed initially for use on halogen containing polymer formulation, especially flexible PVC fo r wires and cables
►ZHS can provide Oxygen Index as well as Smoke Suppressant properties
►By adding Antimony Trioxide you get oxygen index but smoke increases, while by adding ZHS you get oxy gen index as well as smoke suppressant properties
Package & Storage
