01
Nanoporous, not just thin
A fumed-silica nanoporous core delivers ultra-low conductivity at minimal thickness, so linings shed heat without adding bulk.
ABOUT SLM
Engineered to Keep the Heat Where It Belongs
SLM designs and manufactures high-strength nano insulation boards for steel ladles, tundishes, kilns, furnaces, and industrial boilers. Rated for continuous service from 1000 °C to 1200 °C, our boards cut heat loss and lower shell temperature without giving up compressive strength.
SLM was born on the shop floor, where old back-up linings stayed heavy, leaky, and hard to fit — yet heat still found the shell. We built a nanoporous board with aerogel-class insulation and the strength of a rigid panel, made to spec in Nantong and shipped to mills worldwide.
WHY TEAMS CHOOSE SLM
What Sets SLM Apart
Three things every customer gets from each board — and every export order.
02
