Pressure Impregnation is perfect for suppliers and industrial manufacturers of building materials. Burnblock® is a non-toxic, water-based product, which makes it very easy to handle and extremely flexible to use in a wide variety of materials and manufacturing processes.
Moreover, Burnblock is:
- Made only out off natural substances, fully biodegradable, non-toxic, pH-neutral, non-corrosive, and VOC emission free.
- Does not need to be heated when mixed – the fire retardant is fully effective at any temperatures normally occurring during manufacturing processes.
- Available in fluid and powder form and can thus be adapted to suit a company’s individual needs and manufacturing facilities.
- Can meet all current statutory requirements for fire retardants. This makes Burnblock a reliable and safe product that can be used for impregnation of absorbent building materials.
What we say is what we can document – and we are clear and open about what we cannot document.
Our Corporate Social Responsibility >>
We collaborate with a large number of manufacturers, who treat and impregnate building materials with Burnblock. If you are in the market for wood-based fireproofed materials, please feel free to contact us, and together we’ll find the best solution to meet your specific needs.
Large-scale building projects require an effective and non-harmful fire retardant. Burnblock is both non-toxic and an extremely effective fire retardant, making it the perfect solution for most building projects.
