S.No Foam Appendix
1 Airflow test
Measures the ease with which air passes through the foam. Pneumatic foam with low airflow will have poor durability and high compression sets, regardless of density.
2 Bonded foam
Created by gluing shredded flexible polyurethane foam together. Commonly used as carpet cushioning. 100% recycled material and 100% recyclable.
3 Compression set
The measure of the deformation (loss of initial height) of foam after it has been held compressed under controlled temperature conditions for a set time. To determine the compression set, a sample of foam is compressed to 90% of its thickness and held in that fixed position at an elevated temperature for 22 hours. The compression set is commonly expressed as a percent of the foam’s original height.
4 Density
The weight per unit of volume. Foam is normally expressed in pounds per cubic foot (or kilograms per cubic meter). Density is not a measure of firmness; however, higher density foam generally gives better quality and performance.
5 Durability
The measure of how well foam retains its comfort, support, and shape even with frequent use.
6 Elongation
A measure of the degree to which foam can be stretched before it breaks. Elongation is measured at the same time tensile strength is determined.
7 Fatigue
A measure of the load-bearing capacity that describes a softening or loss of firmness. There are two types of fatigue tests: static fatigue and dynamic fatigue. These tests can determine how well a product will hold up over time.
8 Filled foam
Filler added to foam to increase density. The addition of these fillers can reduce the “dish” effect and increase the support factor. Foams with low polymer content or a high percentage of filler material tend to have less resiliency, strength, and durability.
9 Fire Retardant Foam
UL 94 HF 1 & FMVSS 302 Standards. This is a self-extinguished foam when is exposed to fire & can work in high temperatures. Works as Noise cancellation foams
10 Fingernail test
A test is conducted by pressing a fingernail into foam. If it does not recover quickly, the foam core has been improperly produced and will have a board surface feel.
11 Flexible polyurethane foam
Polyurethane foam is used in furniture such as beds, couches, and chairs, because it can mold to the shape of the body, providing comfort and support.
12 Gel Foam
Foam induced with Copper or green gel which acts as a balancing agent for temperature control.
13 Hand Feel
The feel of foam as your hand moves gently over the surface. Foam with a stiff feel has a poor hand and foam that has a velvet feel is described as having a good hand.
14 High resilience (HR) foam
Premium polyurethane foam that has been formulated with higher-molecular weight polyols. As a result, foams have a high support factor, which describes the relationship of the surface comfort to deep-down support. HR foam is primarily sold at high-density levels and is a very high-quality material. The term high resilience was coined based on the improved resilience of these foams when compared to that of conventional foams.
15 Indentation force deflection (IFD)
A measure of load-bearing capacity or firmness. For example, the 25% IFD is determined by measuring the number of pounds it takes to compress the foam by 25% of its original thickness. The 65% IFD reading is obtained in the same way at deeper compression (65% of the sample thickness). The higher the 25% IFD, the firmer the surface feels. Foams with high 65% IFD values resist bottoming-out and provide more support. Note: previously called indentation load deflection (ILD).
16 Lamination
A fabrication process that bonds one foam variety to another using durable adhesives. Lamination can be used to combine foams with differing physical properties to obtain desired combinations of comfort and support.
17 Memory foam or visco-elastic foam
Memory foam is visco-elastic material, which response to body weight and temperature by conforming to the contours of the body, providing personalized comfort and consistent pressure-relieving support.
18 Molded foam
Foam chemicals are poured into a mold to produce a cellular foam product that holds the shape of the mold cavity in which it was produced. The effect provides the foam with unique surface contours. Molded foam can help visually enhance a product line without affecting performance.
19 Premium Foam
Pure Foam made for Mattress, furniture & comfort-grade foam. An all wether foam from Shree Malani foams
20 Recovery
The measurement of the return produced by foam to its original dimension and properties after a deforming force has been placed on the foam and then removed.
21 Resilience
An indicator of the elasticity of foam. It is measured by The Ball Rebound Test by dropping a steel ball onto foam from a fixed height and measuring what percentage the ball rebounds from the original height of the ball drop. Foam has an average resiliency from 40% to 75%.
22 Resilia Zzip
A very premium Roll pack mattress with high reselience & Anti microbial Properties along with a warranty of 25 years.
23 Slab stock production
Liquid raw materials and other additives are mixed continuously with an in-line mixer and then poured onto a moving conveyor. The liquids froth and expand to form a continuous slab of foam that is chopped into sections.
24 Silky / Super soft Foam
Very soft foam yet retains support to enhance comfort. Milled Hypersoft has a down-like softness and a luxuriously soft touch.
25 Tensile strength
A test that measures the pounds per square inch (PSI) of strength required to stretch a material to its breaking point.
26 Ticking
Upholstery and mattress covering made of strong, durable cotton or linen fabric.
27 Toluene diisocyanate (TDI)
TDI is a raw material that reacts with polyols and water to form polyurethane foam. This is a prime ingredient in the synthesis of many visco-elastic memory foam formulations.
28 Urethane
The resultant of the chemical reaction between an isocyanate and an organic hydroxyl. Polyurethane foam is a cellular product produced from the reaction of active hydrogen-containing compounds with blowing agents and polyisocyanates.
