    2.Heat insulation: 

       Low content of slag ball, cotton silk slender and flexiable and low thermal conductivity,very good in heat preservation effect ;

    3.Fire-proof performance:

       Because of its raw material is natural rock,and natural rock itself is A grade,superior in high temperature resistance,don't produce poisonous gas in fire;

    4. Sound-absorbing and noise reduction:

         A large amount of slender pliable rock cotton fiber to form long-short unicom structure many tiny air gap exist internal structure makes the reforms of cotton with efficient sound-absorbing noise reduction and elastic buffer outside physical properties;
