Features and applications:
1. Resistant to aging and low temperature. Mechanical and physical properties, chemical stability, easy adhesion, heat sealing, etc
2. Low thermal conductivity, low water absorption and good water resistance
3. Non toxic, good resistance to steam penetration.
4. Heat preservation, sound insulation, sealing and earthquake resistance of building (central) air conditioning and hot and cold water pipes
