What is ASTM D3574?
What is ASTM D3574?
ASTM D3574 describes a range of tests used to characterize the properties of flexible polyurethane foams. These foams are most commonly used by the furniture, bedding, and automotive industries for the creation of seats and mattresses that will improve consumer ergonomics and maximize comfort.
What is ASTM D3575?
ASTM D3575 outlines 13 tests for determining some of the most significant properties of flexible, closed-cell cushioning materials made from olefin polymers or blends containing olefin polymers (including ETHAFOAM™ polyethylene foam).
What type of material is foam?
Foam is a permeating, lightweight material that is produced by pushing gas bubbles into a polymer material, making it a type of expanded plastic and rubber. Foam fabric can also, when used alongside corrugated packaging, be used to protect products during transportation.
What are the properties of foams?
So Which One is Right for Your Application?
| Foam Properties | Open Cell | Property Measurement |
|---|---|---|
| Compression Force Deflective (CFD) | ✓ | Softness/Conformability |
| Compression Set Resistance | ✓ | Life of Properties |
| Anti-Microbial | ✓* | Integral Coating |
| Breathability | ✓ | MVTR-Yes/No |
What is IFD in foam?
Firmness is an indicator of the surface feel of the foam. It is measured using the force in pounds required to indent a foam sample by 25% of its original height. This measurement is called Indentation Force Deflection (IFD).
How many types of foam are there?
Types of Foam: Different Foam Mattresses Summary Late foam, Polyurethane foam and Memory foam: these are the three basic types of foam used to manufacture mattresses.
What is foam density rating?
Foam density is a unit of measurement that dictates how many pounds polyurethane foam can support per cubic foot. In short, foam density tells you the strength of the foam, and that decimal you’re seeing is the number of pounds each cubic foot can hold.
What is the strength of foam?
Support factors for foam range from about 1.5 to 2.6. The higher the number, the better the ability of the foam to provide support. Foams with higher support factors offer a number of advantages, such as a sitter not “bottoming out” on a sofa or a chair.
What is the density of foam?
Foam densities can range from as low as 0.8 pcf to as high as 6 pcf, with a sufficient range being between 0.9 to 2.5 pcf.
Is 32 density foam good?
High-density foam means higher quality as it has a strong cell structure. Consumers should check the specifications of the foams used. On a standard basis for the Indian market, PU foams should have 32 to 40 density, memory foam should have 50 to 60 density and Latex should have 55 to 65 density.
Which is the best type of foam?
We strongly believe that latex foam is, by far, the best type of foam to use in mattresses. Latex foam offers several significant advantages over Polyurethane foam and Memory foam. Because of this our products never contain any foam other than 100% natural latex foam.
What is Lux foam?
Lux foam is a good quality foam for mattresses and cushions. It is available in medium-firm firmness only. Lux foam will be perfect for many applications as it will provide ample support without being too rigid. It has a quick return action, so it will return to its original shape quickly after compression.
