We are the top 5 pu foam supplier in China. First of all, our 2570 can be compressed to 1cbm from 10cbm, which is cost-effective for logistics fee. Actually, over 540cbm pu foam can be compressed into one 40 foot container, which is unbelievable. Besides, our compression time can be as long as 6 months (warranty time). Moreover, our compressed polyurethane foam passes the REACH test (published by European Chemicals Agency regarding Regulation No 1907/2006 concerning the REACH). Therefore, enters into partnerships with us is an advisable choice.

Specification of Replacement Foam For Couch Cushions

what is pu foam made of

Polyurethane (PU) foam is a flexible and versatile material made from PPG, POP and isocyanate (TDI-80). The three components react chemically to form foam that can be used for a variety of applications, such as cushioning, insulation, and soundproofing.

The polyol component of PU foam consists of polyester or polyether polyols, which are complex organic compounds derived from petroleum. These compounds are typically mixed with other additives, such as catalysts, blowing agents, and surfactants.

The isocyanate component typically consists of methylene diphenyl diisocyanate (MDI) or toluene diisocyanate (TDI), which are highly reactive compounds derived from petrochemicals. The isocyanate is typically combined with the polyol component through a process called polymerization, which causes the two to bond and form the foam.

The specific properties and characteristics of PU foam can be adjusted by varying the type and amount of additives used, as well as the polymerization process itself. As a result, PU foam can be tailored to meet the specific needs of various applications and industries.

How many density are there about the pu foam?

Foam is available in various densities, which indicate the weight of the foam per unit of volume. The density of foam is usually measured in pounds per cubic foot (lb/ft3) or kilograms per cubic meter (kg/m3), depending on the location and the industry.

Here are some common density ranges for foam regarding to the kg per cubic meter:

Low-density foam: 3 to 18 kg/m3(normally are used for wood frame plying-up)

Medium-density foam: 18 to 35 kg/m3(normally are used for sofa back and sofa arm)

High-density foam: 35 to 50 kg/m3(normally are used for sofa seat or mattress)

Super high-density foam:  50 kg/m3 and above(normally are used for shoes pad)

The density of foam affects its properties, such as cushioning ability, durability, and firmness. Higher density foam generally tends to be more durable and supportive, while lower density foam may be softer and more conforming.

The appropriate density of foam for a particular application depends on factors such as the desired level of comfort and support, the intended use, and the cost.
