After radiation crosslinking and high temperature foaming, conductive / anti-static foam plastics are made. Its surface resistance and volume resistance are 103-109 Ω, permanent conductive / antistatic, smooth surface, environmental protection, easy to be processed and molded, ESD foam are widely used in fields related ESD. Characteristic: 1. Permanent conductive / antistatic performance;2. Conductivity / antistatic performance is not affected by ambient humidity;3. Volume resistance and surface resistance 103-109 Ω;4. Easy for secondary molding. The resistance of antistatic foam is 106 – 1011 Ω; The resistance of conductive foam is 103-109 Ω. Due to the difference of resistance value, the electrostatic half-life of conductive foam is far less than that of anti-static foam, and the electrostatic voltage of conductive foam is far less than that of
Working Principle of foil insulation foam
The Heat is an energy, transmits in three ways, conduction, convection, radiation. Through the high temperature to low temperature transfer, and ultimately achieve the dynamic balance of average temperature. Conduction: Air is a poor conductor of heat conduction. The air layer is the best material of anti-heat conductive Such as snow suits, blankets and son on, are all the use of air layer. Convection: Occurs in the material, like liquid, gas. Therefore, cooling need to be installed on the high place, and heating need to be put on the ground (lower), Its principle is using of thermal convection transmission, to achieve uniform temperature as soon as possible. Radiation: The sun’s radiation does not transmit to the Earth through any substance. Aluminum foil can reflect 97% of radiant heat(Emission Rate E=0.03), Aluminum foil insulation material is the best ideal to the anti- heat radiant. Product: Aluminum Foil XPE foam core insulation
What is Irradiated crosslinking polypropylene foam (IXPP foam)
Technical advantages of irradiated crosslinking polypropylene foam (IXPP foam) Irradiated crosslinking polypropylene foam (IXPP foam) products have attracted much attention due to their good thermal stability (maximum temperature up to 130 ℃) and the size stability of products at high temperature, high toughness, tensile strength and impact strength, suitable and compliant surfaces, excellent microwave adaptability and environmental protection.

It is an ideal microwave oven and microwave food packaging material. The hot formed bowls, dishes and packaging materials have high enough
What is thermal conductivity?
What is thermal conductivity? Thermal conductivity refers to the ability of a given material to conduct/transfer heat. It is generally denoted by the symbol ‘k’ but can also be denoted by ‘λ’ and ‘κ’. The reciprocal of this quantity is known as thermal resistivity. Materials with high thermal conductivity are used in heat sinks whereas materials with low values of λ are used as thermal insulators. Fourier’s law of thermal conduction (also known as the law of heat conduction) states that the rate at which heat is transferred through a material is proportional to the negative of the temperature gradient and is also proportional to the area through which the heat flows. The heat transfer characteristics of a solid material are measured by a property called the thermal conductivity, k (or λ), measured in W/m.K. It is a measure of a substance’s ability to transfer heat through a material by conduction. Note

Installing insulation has an immediate impact on energy demand and GHG emissions.• A response to climate change demands well-insulated new and existing buildings. Economic benefits:• Insulation reduces average home heating and cooling costs by around 30%.• Insulation reduces the burden of increasing energy prices.• The cost of installing insulation
Understanding Radiant Heat Transfer and Radiant Heat Barriers
The Sun is our greatest source of heat and we are always in a battle to control that heat in our homes. The heat we experience from the sun is made up of different parts ultraviolet heat visible light heat and infrared heat. When you’re out in the hot sun, you feel it’s 3% from ultraviolet light, 40% from visible light, and 57% from infrared heat. This same heat is what strikes the roof of your home and heats up the inside. When the Sun hits your roof, most of the heat energy is absorbed by the roof and the heat is conducted through the roof assembly towards the cool interior of your home. When the heat come no longer conduct because it hits the air space on the underside of your roof deck. It changes back to radiant heat and transfers down to the next object in its path.
