Duratec®-XP is manufactured from a blend of calcium silicate, calcium aluminates and glass fibre. This composite is tough, highly machinable, electrically inert and displays excellent strength at elevated temperatures. It also provides similar characteristics to plastic when in application as it maintains its flexural performance and does not become brittle.

Due to its characteristics,  Duratec®-XP is commonly manufactured into electrical insulation components, welding pads, thermal breaks, arc chutes and coil supports. We offer a comprehensive in-house machining service and have the capability to manufacture Duratec® into components from existing samples or drawings.

Please note: We previously supplied Duratec® 750 and Duratec® 1000, which have recently been discontinued. As a result, we may offer the following high temperature insulation boards based on your application:

► Sindanyo® H91

► Zircar® RS-1200 (see below)


Duratec-XP® is often used as components in induction furnace and electrically insulating arc chutes.

Key Features

Zircar® RS-1200 

Zircar® RS-1200 is an alternative to the discontinued Duratec® 750 and 1000. The material is manufactured from an alumina composite that provides excellent electrical insulation properties and outstanding thermal strength. It has a maximum operational temperature of +1300°C and is commonly used as heat shielding in foundries, insulation in moulding presses, electrical terminal blocks and induction furnace components.
