Description:
The rock wool product is made from basalt as main ingredient which is made into the fiber in high speed
centrifugal machine after melting at temperature about1450°C. Adding the proportional resin, it can be
processed into rock wool board, blanket and pipe according to the customer requirement.
Applications:
|
Business Organizations |
Indoor and outdoor heat and sound insulation. |
Competitive Advantage:
Excellent heat preservation,machining and refractory properties.
High acidity coefficient,good chemical stability and fiber durabiliy.
