Padding Materials: Polyurethane Foam vs. Reticulated Polyurethane Foam
Padding Materials: Polyurethane Foam vs. Reticulated Polyurethane Foam
January 29, 2019

At kristoFOAM Industries Inc., we produce custom foam padding, among other custom moulded foam products and packaging materials. Our foam padding products are manufactured using one of two types of materials, depending on the product’s applications: polyurethane and reticulated polyurethane. In this blog, we’re going to break down the differences between these two types of materials and the applications each type is best suited for.


Polyurethane Foam

Polyurethane foam refers to any type of foam that contains the polyurethane polymer, which is produced through a chemical reaction between polyol and diisocyanate. After the polymer is synthesized, it is poured into moulds and cooled into a solid form before cutting into custom foam padding products. Polyurethane is the building block for both memory foam and high-density foam. Other compounds can be added to achieve a certain level of density or elasticity. Memory foam mattresses are a well-known product that is made from polyurethane foam; it is also used to pad upholstered furniture and car seats. This foam is ideal for use as cushioning material as it is highly durable.


Reticulated Polyurethane Foam

Reticulated polyurethane foam is produced through the same chemical reaction process as regular polyurethane foam; however, the cells of the reticulated foam are blown open to create a lightweight, open-cell material. The foam is also thermally reticulated to produce a flexible skeletal structure. Reticulated polyurethane foam can have a wide range of porosity—from 10 ppi (pores per inch) to 100 ppi. The porosity and network-like structure of reticulated foam increases airflow, making it resistant to odor and mildew. It is very versatile because of its strength, durability and chemical resistance. Custom foam padding made of reticulated polyurethane foam is used for a variety of purposes, which can be broken down based on the two types of this foam.


The two main types of reticulated polyurethane foam are polyester and polyether. Polyester foam is more rigid and durable, as well as shock absorbent, while polyether foam is more flexible and better able to handle moisture due to its larger cell size. Polyester foam is used for packaging items for transportation or storage and polyether foam is used for filtering air, sound and liquid. Some examples of where this filtration function comes in handy is in water purification, air conditioning filters, speaker grills and humidifier filters and pads.


We supply both polyurethane and reticulated polyurethane foam that can be applied across many different industries, including automotive, electronic and industrial. We use only the highest quality raw materials and we are capable of accommodating fully customized product designs.
