ProRox BL<\/h2>\n

ProRox BL rock wool insulation is a ROCKWOOL rock wool insulation in the ProRox series designed for industrial applications requiring higher heat resistance and more certification standards <\/span><\/p>\n

ProRox BL is a roll-type rock wool insulation used for wrapping heat tanks or boilers, with operating temperatures up to 650 degrees Celsius at a density of 100 kg\/m\u00b3. Due to its wide operating temperature range, it can be used in various applications<\/p>\n

Thermal conductivity<\/h3>\n

This wire mesh roll-type thermal insulation can withstand temperatures up to 650 degrees Celsius and is certified to ASTM C411 and ASTM C447 standards <\/span><\/p>\n

It has also been tested for thermal conductivity according to ASTM C117 standard, which measures thermal conductivity within wire mesh blanket insulation. The results are shown in this table:<\/p>\n

From the material classification table, we can see that ProRox BL rock wool insulation is classified as A1 material, which is non-combustible, does not produce smoke, and does not create flaming droplets, ensuring it can be confidently used as a fire protection material<\/p>\n

Chloride testing<\/h3>\n

In hot water pipe insulation, a common problem is rust that corrodes the pipe surface and interior. This is often undetectable until the jacket and thermal insulation are removed, by which time significant damage requiring costly pipe replacement may have occurred.<\/p>\n

Rust is caused by moisture from water vapor, oxygen, and catalysts like chloride and fluoride, forming brown rust deposits on the pipe surface.<\/p>\n

\"pipe<\/a>

Rust formation on pipe surface due to moisture<\/p><\/div>\n

We can prevent rust formation in several ways, including cleaning the pipe surface before applying protective coating and maintaining the jacket integrity by not stepping on it.<\/p>\n

The ProRox series of insulation reduces the use of chloride water in production, lowering chloride content in the insulation. We tested our insulation according to ASTM C871 standard, which measures chloride, fluoride, silicate, and sodium ion content in thermal insulation to assess potential pipe material damage. Our test results showed only 10 ppm of chloride in the insulation, which is very low and has negligible impact on rust formation.<\/p>\n

Moisture and water vapor<\/h3>\n

Moisture and water vapor accumulation in insulation is another cause of pipe surface rust. Vapor and moisture can come from two sources: inside the pipe (leaks) or outside the jacket. Using ROCKWOOL insulation with an open-cell structure allows easier evaporation of water vapor and droplets compared to closed-cell insulation.<\/p>\n

\"water<\/a>

Water droplets will not penetrate the mineral wool insulation and will evaporate on their own<\/p><\/div>\n

Additionally, ROCKWOOL insulation is treated with silicone water repellent during production, making every fiber water-resistant. If water droplets fall on the insulation, they will bead up, or if water is poured on the insulation, it will flow over the surface like on a car windshield.<\/p>\n

We also tested rock wool insulation according to ASTM C1104\/C1104M standard to determine water absorption of the rock wool insulation, with test results showing rock wool insulation absorbs only 1% of water by weight<\/p>\n

Mineral wool insulation causing cancer<\/h3>\n

Only in Thailand is there concern about “mineral wool” causing “cancer”. This is a misunderstanding due to translation issues. Mineral wool insulation (ROCKWOOL) and asbestos are confused due to similar terminology. We will explain the difference.<\/p>\n

\"asbestos\"<\/a>

Image of asbestos<\/p><\/div>\n

Asbestos mineral fibers<\/strong> are naturally occurring mineral groups with white fiber characteristics smaller than 0.1 microns, formed from silicate mineral raw materials. They can disperse in air and fibers can break down continuously into sharp, pointed forms that are carcinogenic<\/p>\n

\"material<\/a>

Image of ROCKWOOL insulation<\/p><\/div>\n

ROCKWOOL rock wool insulation<\/strong> is produced through controlled manufacturing processes using standard machinery that melts basalt and dolomite rocks to spin out fibers sized 4-6 microns. Fibers can break with rounded ends too large to enter lungs and are non-carcinogenic<\/p>\n
