·The mixing ratio is based on the optimal mixing ratio value, which will vary with the type and amount of pigment additives added.
·Long-term storage of P-5608 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 2 6mm incisions are pre-cut at the folding area, 23oc × 40,000 times.
·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.
