Perlite Board & Pipe
Expanded perlite board or pipe has unique internal structure, which consists of numerous tiny closed air cells, with exterior irregular surface, thereby features good thermal and acoustic insulation properties.
Features of perlite:
- High operating temperature;
- Non-combustible and water repellent;
- High compression resistance;
- Excellent corrosion and moisture resistance;
- Extremely light weight;
- Asbestos - free.
