Hexaphenylcyclotrisilazane

Hexaphenylcyclotrisilazane IOTA 5213

Chemical name: 1,2,2,3,4,4-hexaphenyl-1,3,5,2,4,6-triazatrisilinane

Description

Hexaphenylcyclotrisilazane is one of the most important cyclosiloxanes. It has good hydrolysis stability because its phenyl groups have high steric hindrance.

Technical index

Appearance: White crystal

Hexaphenyl cyclotrisilazane content: ≥98.0%

CAS No.: 4570-25-6

Molecular weight: 591.924

Density(25℃)g/cm³: 1.19

Flash point(close cup: 330.135℃

Solubleness: Can be soluble in toluene, heptane and other organic solvents.

Application

It can effectively improve heat resistance of silicone rubber if it is applied into heat resistance agent to prevent oxidative crosslinking and main chain degradation of silicone rubber side chains. And when it is heated at temperature of 400℃ for a long time, it can be formed into polymer for a good heat resistance coating.

Package

25L plastic drum or 210L closed coated iron drum.

Shelf life: 12 months from production date.

Storage

Store it at cool, ventilated warehouse. Temperature of the warehouse should <37℃. Please do not put it along with oxidant, edible chemical and readjusting. Keep container sealed. Be far away from fire, heat source.

Precautions:

1. The material must be used in well-ventilated place. Wear necessary safety protection to avoid over inhaling in processing. Do not eat.

2. Handle with care, details refer to MSDS. In addition, safety regulation of country or local government should be obeyed.
