Support Factor (see Compression Modulus) - Support Factor is a ratio os 65% IFD.25% IFD. When the support factor is known, it can be used in conjunction with a known 25% IFD value to determine the 65% IFD value. Seating FPFs with low support factors are more likely to bottom out.
Comfort - The ability of thecushioning structure to deflect at the surface and to conform to body shape, preventing a concentration of pressure on the body. Compression Modulus - Ratio of an FPF's ability to support force at different indentation (or compression) levels. It is determined by taking the ratio of the FPF's IFD at 25% indentation and 65% indentation (65% IFD/25% IFD). The compression modulus is typically a function of FPF chemical formulation and the manufacturing process. IN most cases, the higher the density the greater the compression modulus. Other terms that are used interchangeably are: support factor, and modulus.
High Resilience (HR) FPF - High Resilience FPF have a high support factor and greater surface resilience hat conventional FPFs and are defined in ASTM D3770. High resilience FPF has a less uniform (more random) cell structure, different from conventional products. The different cell structure helps add support, comfort, and resilience or bounce
California Technical Bulletin 117 FPF - FPF that will meet the component combustibility requirements of this standard.
