introduction to flame retardant grades of tpu films

flammability ul94 rating is the most widely used flammability performance standard for plastic materials.

it is used to evaluate the ability of a material to extinguish after being ignited.

there are many evaluation methods based on burning speed, burning time, anti-drip ability and whether the dripping beads burn.

many values can be obtained for each material being tested based on color or thickness.

when selecting a material for a product, its ul rating should meet the thickness requirements for the wall portion of the plastic part.

the ul rating should be reported together with the thickness value. it is not sufficient to report the ul rating without thickness.

plastic flame retardant grades increase from hb, v-2, v-1, v-0, 5vb to 5va:

tpu film

hb: the lowest flame retardant grade in the ul94 standard. it is required that for samples between 3 and 13 mm thick, the burning speed is less than 40 mm per minute; for samples less than 3 mm thick, the burning speed is less than 70 mm per minute; or it is extinguished before the 100 mm mark.

v-2: after two 10-second combustion tests on the sample, the afterflame & afterburning went out within 60 seconds. dropping particles can ignite cotton.

v-1: after two 10-second combustion tests on the sample, the afterflame & afterburning went out within 60 seconds. dropping particles must not ignite cotton.

v-0: after two 10-second combustion tests on the sample, the afterflame & afterburning are extinguished within 30 seconds. dropping particles must not ignite cotton.

5vb: after five 5-second burning tests on the sample, the afterflame & afterburning is extinguished within 60 seconds. dropping particles must not ignite cotton. burn-through is allowed for bulk samples.

5va: after five 5-second burning tests on the sample, the afterflame & afterburning is extinguished within 30 seconds. dropping particles must not ignite cotton. block samples are not allowed to be burned through.
