¡¤Long-term storage of P-3545 will cause the internal components to stratify, so stir evenly after heating and dissolving before use.
¡¤The density of free foam will vary depending on the season (temperature, humidity).
¡¤The demoulding time will increase as the thickness of the molded product increases.
¡¤The physical property data is obtained by testing a 6mm thick test piece.
¡¤Folding endurance conditions: The bending angle is 90 degrees, the frequency is 230 times/min, and an average of two 6mm incisions are pre-cut at the bending area.
¡¤The above data is for reference only, and the specific data is subject to actual operation. If you need other physical property indicators, please contact our company.
