PANZHU WRAP rock wool board, is a selection of high-quality basalt as the main raw material, after high temperature melting, adopting international advanced system of four roll centrifugal cotton process, to basaltic rock wool high temperature melt into a discontinuity of the 4 ~ 7 microns fiber, and then add a certain amount of binder in rock cotton fiber hatred, dust, oil, water, after sedimentation, curing, cutting, such as technology, according to the different USES to make series of products of different density.

PANZHU WRAP the characteristics of the rock wool board:
1, high fire resistance  PANZHU WRAP rock softening point of cotton fiber in 900-1000 ℃, 600 ℃ in the long-term use will not change any.
2. Contraction temperature under thermal load: 643 degrees
3, water proofing property: PANZHU hygroscopicity of WRAP rock wool board is only 3.9% (100 - kilogram water cut into 3.9 kg) by rock wool board, completely does not affect its performance.
4, low organic matter content: on bamboo ® PANZHU WRAP rock wool board the organic matter content of 2.9% (organic matter content is lower, the product of the flame retardant, sound insulation, heat preservation effect, the better)
5, sound absorption and sound insulation: with its different thickness, can reduce the noise of 30-50 decibels, lightweight strip series of internal material (EPS polystyrene particles) has good sound insulation performance and sound absorption performance.
6. Durability: the acidity coefficient represents the durability of rock wool board. National standard requires 1.6 or higher, on the Banks of the PANZHU WRAP the acidity coefficient of rock wool board are 2.0 or higher, suitable for high-rise buildings on the thermal insulation layer application of high demand.
7, insulation performance:  PANZHU WRAP rock wool board (room temperature) thermal conductivity is 0.035 W/m2. K


 PANZHU WRAP the application of rock wool board

1,  PANZHU WRAP moistureproof rock wool board: Marine rock wool board used in thermal insulation and fire partition; Hydrophobic rock wool board for vehicles, mobile equipment, cold storage engineering, air conditioning pipes and in the humid environment in the heat preservation and fire prevention and moisture-proof have certain requirements of the application occasions.

2, PANZHU WRAP rock wool board excellent fire protection, thermal insulation and sound-absorbing properties: it is mainly used for building wall, roof insulation sound insulation; Fire and noise reduction of building partitions, firewalls, fire doors and elevator shafts.
Range of application
Petrochemical industry - oil, electric power, chemical industry equipment insulation sound absorption noise reduction
Construction industry - acoustic insulation and noise reduction for building partitions, curtain walls, roofs and enclosures
Industrial and mining industries - industrial kilns, ovens, large-diameter storage tanks and ship fire insulation, etc
