- ●The data are tested values and not standard ones. The specifications can be altered without any notification.
- ○：Applicable
- *1：The condition is to be exposed at 200 degrees Celsius and for 24 hours.
- *2：The condition is to be exposed at 200 degrees Celsius and for 72 hours.
- *3：The condition is to be exposed at the density of 500ppb, 40 degrees Celsius, with 10% elongation and for 24 hours.
- Note)For flame-retardant tests for railroad vehicles, it is necessary to determine whether or not they are compatible with each thickness, so please consult us separately.
