                                                           What is insulation sheet?
Insulation sheet is a kind of insulation material products, with excellent performance of NBR and PVC as the main raw materials, with a variety of auxiliary materials, through special formula and process mixing, extrusion, foam molding as the final product, the main function is keep warm, the main color is black.
With the strong quality of stretching and bending, insulation sheet can withstand tearing and rough force transfer, and has the characteristics of high temperature (-40-+110 degrees). It is made of 100% advanced NBR material, which will not be damaged under severe conditions.
Insulation sheet contains a variety of anti-aging, anti-ultraviolet, anti-ozone, resistance to extreme temperature and flame retardant, shock absorption, good sound absorption, flame retardant, self-extinguishing, non-flame, so it has excellent aging resistance and long-term resistance to severe cold. The ability to withstand harsh environments such as heat, dryness and humidity, and long service life.
It can be used in various fields, household air conditioning and construction, chemical industry, metallurgy, shipbuilding, medicine, automotive, refrigerators, freezers, household electrical appliances, engineering refrigeration and cold storage and refrigeration, vehicle engineering and other industries of all kinds of cold and heat pipes, construction and installation, such as building heat insulation heat preservation of the thermal insulation material. Because it is closed-cell foam, so it has good damping and shock resistance, heat insulation and buoyancy excellent performance, etc.
The most common is the pipe, which is easy to cut and has no special requirements for the shape of the object to be insulated. It is used in the air conditioning and some refrigeration industries, and you can use it to keep things warm, such as in some areas that require refrigeration. It acts as a thermal barrier so that your food is not susceptible to deterioration..And to air conditioning,it is generally used to make ventilation pipes, such isolate air, also can have the effect of heat preservation.
Although the raw materials of insulation sheet are few, but the process is still troublesome, which needs to be foamed and has certain requirements for the machine. Of course, under such a high process level, the insulation sheet produced is also very high-grade, and the insulation effect is very good.
