1)What is PE foam?
A: Polyethylene foam is a strong, resilient closed-cell foam. Ideally, foam material suited as the material or part of a material required in products requiring a shock absorbing, vibration dampening, insulation, barrier or buoyancy component etc.
2)What is closed-cell?
A: Polyethylene foam is closed-cell, meaning it consists of cells so tightly packed together that it gives the appearance of one uniform structure.
The reality is that the individual cells within polyethylene foam do not physically connect to one another.
This cellular formation is similar to fish caught in a fisherman's net.
3)Why choose Low-density polyethylene foam?
A: Low-density polyethylene foam has numerous applications because of its many desirable properties including water-resistance, chemical resistance, energy-absorbance, buoyancy and cushioning characteristics. Compressive strength is greater in denser foams, decreasing as density decreases. Low-density foams tend to exhibit more compressive creep, meaning they become less thick over time, than higher-density foams.
4)How can I know the suitable foam density I need?
A: Our PE foam density is between 25 kg/m3 and 240 kg/m3
We can provide the best solution for you according to the application, Density, hardness, thickness.And The free sample is available for your confirmation and text
