Features

Excellent Flame Resisting
Saran™ is inherently self-extinguishing, making the addition of flame-retardants unnecessary. This means consistent, uniform flame-retardant properties, free from variations which occur during flame-retardant compounding.

Saran™ Flame Resistant result(JIS-L-1091)
As these figures noted above are only for reference, please check the resistance before using.

tearstrength :Record the maximum load at the time of tear when a notch of 10cm (or 5cm) is formed in the specimen.
bursting strength :A 15cm angular specimen is sampled,and a Mullen bursting strength tester is employed.
Pressure is applied via a rubber diaphragm, and the strength at which the rubber diaphragm breaks through the specimen
"A"(kPa), and the strength to rupture the rubber diaphragm alone "B"(kPa) are measured, and the bursting strength (kPa)
is calculated by the following formula.
<Fomula>
bursting strength = A - B
shrinkage :The shrinkage after immersion in boiling water for 30 minutes
