Static Compression Force Measurements

1)Compression force measurements were conducted on H0.9mm*W1.1mm*L10mm D shapestrip of CG-6020, representing static conditions.

2)All strips were extruded then post-cured and put for over 24 hours prior to testing. Data was collected from tests of a new sample strip, measuring the force the first time the strip was compressed. Subsequent compressions will yield a smaller value than the first compression of the strip.

3)Static compression force measurements were made according to NysteinmethodQA-WI-FIP-003. Compression of the strip to a fraction of the original free height was followed by a hold of thirty seconds to allow the strip to equilibrate before the force was measured. The strip was then further compressed, equilibrated, and another measurement performed. Typical results for CG-6020 are shown in Figure 2Table 9, below.

4)The data shown below can help customer to design structure & application.

Section 5: Flammability

1)Cured CG-6020 is UL-94 tested and is V-0 rated for sample size is 127mm*12.7mm*2mm.

2)Test procedure:

a)Clamp the specimen from the upper 6 mm of the specimen, with the longitudinal axis vertical, so that thelower end of the specimen is 300 ±10 mm above a horizontal layer of not more than 0.08 g of absorbent 100percent cotton thinned to approximately 50 x 50 mm and a maximum thickness of 6 mm.

b)Adjust the burner to produce a blue flame 20 ±1 mm high.

c)Apply the flame centrally to the middle point of the bottom edge of the specimen so that the top of theburner is 10 ±1 mm below that point of the lower end of the specimen, and maintain it at that distance for10 ±0.5 seconds.

d)After theapplication of the flame to the specimen for 10 ±0.5 seconds, immediately withdraw the burner at a rate ofapproximately 300 mm/sec, to a distance at least 150 mm away from the specimen and simultaneouslycommence measurement of the afterflame time t1 in seconds. Record t1.

e)As soon as afterflaming of the specimen ceases, even if the burner has not been withdrawn to the full150 mm distance from the specimen, immediately place the burner again under the specimen and maintainthe burner at a distance of 10 ±1 mm from the remaining portion of the specimen for an additional 10 ±0.5seconds, while moving the burner clear of dropping material as necessary. After this application of the flameto the specimen, immediately remove the burner at a rate of approximately 300 mm/sec to a distance of at least150 mm from the specimen and simultaneously commence measurement of the afterflame time, t2, and theafterglow time, t3.
