The density of epe pearl cotton material is calculated in kg/m3 (kg per cubic meter), the current market pearl cotton is divided into several grades. epe pearl cotton density how to calculate? The next EPE Foam Sheet Extrusion Line manufacturer to give you an introduction.


Polyethylene foam cotton, also known as epe pearl cotton, is a non-cross-linked closed-cell structure of new environmentally friendly packaging materials. It consists of low-density polyethylene resin by physical foaming to produce numerous independent bubbles. Overcome the shortcomings of ordinary styrofoam fragile, deformation, poor recovery. It has many advantages such as water and moisture barrier, shockproof, sound insulation, heat preservation, good plasticity, strong toughness, recycling, environmental protection, strong anti-collision, etc. It also has very good chemical resistance. It is an ideal substitute for traditional packaging materials.


The general density of pearl cotton range from 20 to 28kg/m3, high density also has 35kg/m3. specific density level you need to consult the vendor. Professionals said that the density of pearl cotton and quality is a significant relationship, in general, the greater its density, then the better the quality of the product, because the density means that it is faster to recover after the pressure, but also that the effect of the elasticity of pearl cotton is relatively good.


When used to package goods, you can ensure that it will not be harmed, there is a greater density of epe pearl cotton, although its softness is low, but by the time of heavy extrusion can also maintain a certain toughness, the current market pearl cotton density level of many, depending on the main demand for the corresponding density.

So, how do we know the density of pearl cotton?


The following is the formula commonly used in the industry to calculate the density of pearl cotton: pearl cotton density (kg/m3) = weight / pearl cotton volume (length * width * thickness) For example: pearl cotton 52 meters long, 1 meter wide, 0.007 meters thick, weight 11 kg, then, its density is 11 / (52 * 1 * 0.007) = 30.22 kg / cubic meter.


But we often encounter some drawings marked degree of this item are similar: 2.2PCF, 4.0 or 2.2lb, that in the end what does it mean?


In fact, it is very simple, because Europe and the United States still follow their traditional units of measurement, including density. PCF is actually (Pounds Per Cubic Foot) pounds / cubic feet of the abbreviation, 2.2PCF referred to as 2.2 pounds, in fact, there are cubic feet omitted after not read. So how to convert the density of it? In fact, as long as you can master this formula: 1 pounds / cubic foot (lb / ft3) = 16.02 kg / cubic meter (kg / m3)
