    Handling & Transport Information

    Nefalit Millboard should be transported flat and fully supported wherever possible. Avoid bending, flexing, or placing heavy items on unsupported areas, as this may cause cracking, corner damage, or breakage. Minor edge or corner damage can occur during handling and transport and does not normally affect the thermal or electrical insulation performance of the board.

    Is Millboard the right option?

    Millboard is best suited where a machinable thermal insulation board is required for gaskets, heat shields, fabricated components or electrical insulation. If you need greater rigidity, higher temperature resistance, or a lightweight board for extreme heat, one of the alternatives below may be more suitable.

    Product Best For Temperature Rating Handling / Structure
    Millboard Machined parts, gaskets, heat shields and electrical insulation Up to 850°C for primary stocked grade Machinable board — transport flat
    Calcium Silicate Board Rigid structural insulation for general high-temperature applications 1100°C Rigid board — transport flat
    Ceramic Fibre Board Lightweight insulation for very high temperatures and thermal shock environments 1260°C+ Lightweight and fragile — transport flat
    Superwool Plus Board Advanced lightweight insulation with improved handling characteristics 1200°C classification / 1000°C continuous Lightweight board with improved handling characteristics

    Need a rigid board for ovens, furnaces or pizza oven insulation? Consider Calcium Silicate Board. For lightweight high-temperature insulation, see Ceramic Fibre Board or Superwool Plus Board.
