Polyurethane is mixed and foamed by a mixture of two-component AB material (isocyanate and combined polyether). It is the lowest thermal conductivity of the thermal insulation material. The thermal conductivity is 0.017~0.024 (the lower the thermal conductivity, the better the thermal insulation effect). Polyurethane sandwich panel is made of polyurethane filling and infusion process. The insulation board is prefabricated in advance and then installed directly on site.

Overview

Rock Wool sandwich panel is usually used for wall and ceilings, which has certain requirements for fire resistance. In addition, it has very good thermal insulation properties. Thus, most of customers like the rock wool sandwich panels. Rockwool sandwich panels are commonly used in clean room engineering in electronics and pharmaceutical plants.

Rock wool is a kind of inorganic fiber board which is mainly made of basalt and it melted at high temperature. Rock wool board is a new type of heat preservation, flame insulation and sound absorption material.
The artificial inorganic fiber processed by high temperature melting of rock wool board has the characteristics of light weight, small thermal conductivity, heat absorption and non-combustibility.

Rock Wool Features
Fire prevention

outer wall rock wool board contains natural volcanic rock, which is a fireproof material for non-combustible building.

Main fire protection features:
1. It has the highest fire rating A1, which can effectively prevent the fire from spreading.
2. The size is very stable and will not stretch, shrink and deform during a fire. 
3. High temperature resistance, melting point higher than 1000 °C. 
4. No smoke or burning droplets/fragments in the fire. 
5. Do not release substances and gases that are harmful to the environment.

Thermal insulation
The outer wall rock wool board fiber is slender and flexible, and the content of the slag ball is low. Therefore, the thermal conductivity is low and the insulation effect is excellent.
Sound absorption and noise reduction
Rockwool is an ideal sound-insulating material. A large number of elongated fibers form a porous joint structure, which determines that the reachable rock wool is an excellent sound-absorbing and noise-reducing material.

Hydrophobic
The water-repellent rate of the Yanshui rock wool product can reach 99.9%; the water absorption rate is extremely low, and there is no capillary penetration.

Moisture resistance
Rock wool in a relatively high humidity environment, the volume moisture absorption rate is less than 0.2%. According to ASTM C1104 or ASTM1104M method test, the mass moisture absorption rate is less than 0.3%.

Non-corrosive
Rock wool is chemically stable, with a pH of 7-8, neutral and weakly alkaline, for carbon steel and stainless steel. 
Metal materials such as aluminum are free of corrosion.

Safe and environmentally friendly
Rockwool has no asbestos, CFC, HFC, HCFC and other environmentally harmful substances. It will not be corroded or produce mildew and bacteria. The rock wool has been identified as a non-carcinogenic substance by the international cancer research authority.

Overview of PU Sandwich Panel
PU sandwich panel usually be named as polyurethane sandwich panel, PU color steel panel aas well as PU composite panel, and it has three layers, which contains double color steel sheet and the PU core, thus, it havs good insulation feature and smoothness.
Polyurethane material is a polymer material. Polyurethane is an emerging organic polymer material and is known as the “fifth largest plastic”. It is widely used in many fields of the national economy due to its excellent performance. PU Sandwich Panel applications  cover the fields like light industry, chemical, electronics, textile, medical science, construction, building materials, automotive, defense, aerospace, aviation and so on.
PU Features
1. Hard polyurethane has low thermal conductivity but good thermal performance. When the density of rigid polyurethane is 35-40 kg/m3, and the thermal conductivity is only 0.018~0.024w/(m.k), which is equivalent to half of EPS and the lowest thermal conductivity of all thermal insulation materials.
2. Rigid polyurethane has moisture and water resistance. The rigid polyurethane has a closed cell ratio over 90%, and it is a hydrophobic material. It does not increase the thermal conductivity due to moisture absorption and seep proof wall.
3. Rigid polyurethane fire, flame retardant and high temperature. Polyurethane is a flame-retardant self-extinguishing material after adding flame retardant. Its softening point can reach above 250℃. It will only decompose at higher temperature, in addition, polyurethane will be in its foam when burned. Carbon deposits form the surface, which helps to isolate the underlying foam. It can effectively prevent the spread of flame. Moreover, polyurethane does not generate harmful gases at high temperatures.
4. Due to the excellent thermal insulation performance of the polyurethane sheet, the thickness of the outer protective structure of the building can be reduced and the indoor use area can be increased.

As one of the most professional polyurethane sandwich panel suppliers in China, our PU Sandwich Panel has below advantages:

Production Advantages:
1. Better thermal insulation;
2. Light weight;
3. Easy to installation;
4. Good smoothness;
5. Water proof, wet proof;
6. No poison, no smell.

Clean room sandwich panels are main products in clean room engineering, which are flame retardant, soundproof and environmentally friendly. The sandwich panel clean room is made up of two layers of metal panels and a functional material from the middle. It has the characteristics of easy installation, light weight and environmental protection. Moreover, the functional materials used for filling can be chosen according to different environments and production requirements. Currently, the core functional materials we can provide are: PU, PIR, Rock Wool, Aluminum Honeycomb, Paper Honeycomb, Magnesium and etc.

Clean room insulation sandwich panel is available in both metal and non-metallic panels. Metal panels are easy to shape and can be made into various shapes, but in some cases non-metallic panels have advantages over metal panels, such as corrosion resistance and impact resistance. Currently, the non-metal plate we can provide refers to the HPL panel.

Clean room sandwich panels(custom clean room rock wool panel) are widely used in large industrial plants, warehouses, stadiums, supermarkets, hospitals, cold storage, mobile homes, building plus floors, clean workshops and places where insulation and fire protection are required. Clean room panel has beautiful appearance, beautiful color and good overall effect. It contains load-bearing, heat preservation, fireproof and waterproof integration. It does not require secondary decoration, meanwhile, the installation is quick and convenient, construction period is short, comprehensive effect is good. It is a kind of versatile, efficient and environmentally friendly building materials with potential.
