PRODUCT DETAILS

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.

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

ZHS is delivered in drum with inner bag, net weight 25.0±0.1kg .

Store in a dry and ventilated warehouse.Minimum shelf life is 12 months under proper stored condition.
