Factors affecting the effect of slow rebound: NCO index
The effect of NCO index on slow rebound.
Low: soft, slow recovery speed, blowing can be seen, rough openings and bubble cells.
High: hard, fast recovery speed, no blowing, closed pore to shrinkage, fine bubble cell.
(Effect of index on Y-1030, TDI index; index 86; SRT 1.8. 65% ILD 0.6, elongation about 180, tensile strength about 0.9, tear strength about 0.4, index 89; SRT 1.5, 65% ILD 0.5, elongation about 180, tensile strength about 1.0, tear strength about 0.5. At an index of 95; SRT is 0.6, 65% ILD is 10.5. Elongation is about 155, tensile strength is about 1.2, and tear strength is about 0.6).
Factors affecting the effect of slow rebound: the effect of water
Water level
Low: High density, soft, closed cell to shrinkage, fine cell structure.
High: low density, hard, open pore, rough cell structure.
Factors affecting the effect of slow rebound: the impact of silicone oil
(F-242T)
Low: slow response, no blowing, closed cell to shrinkage.
High: fast response, blowing, open pores, rough cell structure.
Factors affecting the effect of slow rebound: the effect of the number of Y-1030
Influence of the number of Y-1030 on hardness (ILD) and rebound time (SRT).
When the proportion of Y-1030 is 40~50%, 65% ILD is about 12~22. SRT is about 0.75~1.1. 55%; 65% ILD is 35, SRT is 1.1. 60% Y-1030; 65% ILD is about 55, SRT is 3.
Y-1030 at 40%; elongation is about 165%, tensile strength; 1.4kg/cm2, tear strength; 0.8kg/cm. at 50%; elongation is about 145%, tensile strength; 2.2, tear strength; 1.2. at 55%; elongation is about 140, tensile strength; 170, tear strength; 1.5. at 60%; elongation is about 120, tensile strength; 1.5. About 120, tensile strength; 185, tear strength; 1.8.
Factors affecting the effect of slow rebound: Effect of POP (white oil)
POP (Y-7730)
POP (Y-7730) ratio from 0% to 14%; 65% ILD from 12 to 20, SRT is 1.5.
POP (Y-7730) ratio at 18%; 65% ILD by 20, SRT is 1.1.
