PI foam is synthesized into PI aerogel by supercritical process. The product retains the excellent performance of PI foam, and the thermal conductivity is greatly reduced.

PIA is a three-dimensional cross-linked porous material composed of polymer molecular chains. Combined with the excellent performance of PI and aerogel, PIA not only has the excellent characteristics of PI, but also has the outstanding characteristics of aerogel, such as lightweight, ultra-low density, high specific surface area, low thermal conductivity, low impedance, environmental durability and low dielectric constant. These special properties make PIA materials have excellent application prospects in thermal, electrical, mechanics, acoustics and other fields.

The aerospace H series polyimide foam products produced by our company can meet the strict requirements in the aerospace field, and are ideal heat insulation and sound absorption materials. Its density ranges from 4 to 6KG/m3, and it is lightweight. Essentially flame retardant, its outstanding flame retardant performance can meet the flame propagation requirements of the radiation plate in FAR25.856 (a), with ultra-low smoke generation, almost no toxic gases or smoke release, good weather resistance, acid and alkali resistance, long service life, and no water absorption failure. Compared to the potential carcinogenic risk of quartz cotton, this series is environmentally friendly and non-toxic.

Ship C series polyimide foam products are used as thermal insulation and sound absorption materials on naval ships and merchant ships around the world. In bulkheads, ceilings, ventilation ducts, pipes and other locations, the use of C series foam products can achieve the ideal heat insulation and noise reduction function, and the weight is extremely light, which is several tons lighter than the use of glass fiber insulation and noise reduction materials. Another outstanding performance of this series of foam is that it has good intrinsic flame retardancy, minimal smoke and non-toxic characteristics when burning.The polyimide foam has passed the International Maritime Organization (IMO) code for flame retardancy of high-speed ships. According to the material demonstration, this series of marine foam has been used in naval ships and a large number of commercial ships in more than 15 countries in the world for heat insulation and noise reduction.

Compared with other thermal insulation materials currently used, phenolic foam, glass wool and mineral wool, the minimum density can reach 6KG/M ³.

Auto Q series polyimide foam products are inherently flame retardant, environmentally friendly and non-toxic, have a wide temperature tolerance range, low thermal conductivity, radiation resistance, UV resistance, light weight, non absorbent, slag free, easy to process and install, and have excellent comprehensive performance. They can be used for a long time under extreme conditions such as ultra-high temperature, ultra-low temperature, high salt spray, strong noise, strong corrosion, strong radiation, and have extremely high reliability and quality assurance.

Due to the uneven performance of each unit battery in naval power batteries, when one battery in the battery pack overheats and burns, it will ignite the entire battery pack. Use power battery E series polyimide foam products to separate each battery unit. When a battery burns, the adjacent battery will not explode due to excessive temperature to avoid major accidents.

In addition, in extremely cold areas, due to the low temperature, the battery discharge is not sufficient or cannot be discharged. The power battery E series polyimide foam product is used to insulate the battery to ensure that the power battery has a relatively high discharge capacity and ensure the normal operation of the electric vehicle.

There are three main ways of heat transfer on urban rail transit vehicles: heat conduction, convection, and radiation. In order to reduce the discomfort caused by vehicle heat transfer to passengers, reduce vehicle energy loss, and improve energy utilization, insulation materials must be laid in appropriate positions inside the vehicle body. Considering the insulation and fire protection requirements of vehicles, insulation materials must have the characteristics of flame retardancy, non toxicity, good insulation and sound absorption performance.

The excellent comprehensive performance of polyimide foam makes it an ideal choice in the construction field.

Flame retardant, non volatile gas, non-toxic, non absorbent, good weather resistance, acid and alkali resistance, it has become the highest quality new material for wall insulation, indoor noise reduction, and ceiling insulation in the construction industry.

PI RIGID FOAM CONNECTOR 

High temperature resistance 

High insulation 

IP67 waterproof

Adopting copper bar+PI hard foam integrated molding technology, the insulation and heat insulation sealing connector can withstand a temperature of 400 degrees Celsius for 1 hour, with low thermal conductivity and high insulation, solving the risk of high-temperature gas passing through the plug-in position in case of thermal runaway of the battery.

The best environmentally friendly solution - PI foam insulation sleeve for medium and low temperature insulation from -260 ℃ to 250 ℃. The heating and insulation sleeves which are widely used in industries such as petrochemicals, food and medicine, liquefied natural gas, etc., have the advantages of environmental protection, non toxicity, low thermal resistance, and long service life.

Using 0.25mm PI foam to wrap BUSBAR copper bars, it has high pressure resistance, high temperature resistance, flame retardancy, and meets European environmental requirements such as REACH and halogen-free.

Mobile phone - battery insulation buffer.

When charging a mobile phone battery, the expanding size is 0.005mm, which extends the battery's lifespan.

Polyimide foam is a new type of foam material produced by polyimide prepolymer, foaming agent, stabilizer and other additives through polymerization and foaming reaction. Polyimide foam is the most potential heat preservation and sound attenuation material in this century. Compared with all heat preservation and sound attenuation materials on the market at present, polyimide foam has a higher sound attenuation index, lower thermal conductivity index, intrinsic flame retardancy, higher resistance to high and low temperatures, better hydrophobicity, better resilience and toughness, no dust, no slag, acid resistance, alkali resistance, oil resistance, radiation resistance, UV resistance, long service life, and lightweight. It is the heat preservation, sound attenuation and flame retardant material with the best comprehensive performance at present.

The emergence of this material means that we have mastered core technologies in the field of cutting-edge insulation and noise reduction, and will have qualitative breakthroughs in many key technological fields. Polyimide foam will enable us to achieve significant progress in key areas such as aerospace, aviation, national defense, rail transit, passenger cars, special thermal insulation vehicles, new energy, etc.
