Thermalite

Thermalite a specific type of fuse used in pyrotechnic applications.

This fuse is used in high-power model rocketry as a means of simultaneously igniting multiple "clustered" rocket motors. A single flashbulb or flash pan is used to ignite pieces of Thermalite leading to each motor.[1]

Thermalite comes in three burn rates identifiable by the colour of the fuse wrapping:

Thermalite safety fuses and connectors were manufactured in Quebec by ICA Canada Inc., however in November 1995 they ceased manufacturing of detonator cord.[2] Sources for thermalite are increasingly hard to come by and purchasing it by mail will usually require permits and licenses.[3] As a result, those who want to use thermalite fuses will sometimes make their own.[4]
