Typical values were tested on the 1mm sample strip by squeezing film extrusion after mixing compound of A& B (at percentage of 95:5), double-sided exposure in the constant temperature and humidity box (23℃, relative humidity 75%) and measured after 48 hours.

*Especially, these typical values were tested on fully solidified and cured sample (If the sample is not fully cured, it will continue the curing during ageing procedure, and consequently will affect the test result before and after heat ageing).

**Especially, these typical values were tested by press moulding sample under the condition of 180±2 ℃, 15min, and pressure over 15Mpa, then boiled in 90℃ water for one hour.

Recommended Processing Technique

1. Extrusion Equipment

The product is easy to be plasticized, ordinary PVC-use single screw extruder (length-diameter ratio is 15 to 20) can be used,the equipment requirement is relatively simple screw structure and the flow wayis smooth and no dead end.

2. Extruder processing temperature and other related settings

Temperature Setting: Specific processing temperature should be based on different equipment and pressing conditions, reference settings are as following:

Die head setting: 4214N is suitable for squeezing extrusion style, half-tubing extrusion style and tubing extrusion style. 4244N is suitable for tubing extrusion method. To produce with tubing extrusion style, the recommended draw ratio is less than 1.2 (4214N) / 1.3(4244N), the greater the draw ratio the greater the thermal shrinkage.

Cooling water temperature: Should not be less than 25℃,gradual cooling water tank is recommended.

Conductor temperature: Appropriate warm-up the copper or aluminium conductor, which can further reduce the heat shrinkage of the insulation and accelerate the cross link speed.

Crosslink Speed

For the cable made from this material, the cross link speed has close relation tothe insulation thickness, ambient temperature, environment humidity and coilsize. The thinner and smaller the coil size, the higher temperature and humidity, the shorter the time needed for cross linking. During cold and dry winter season, the crosslink speed in natural environment will be comparatively slow down. To reduce the cross linking time, it is recommended to spray somehot water on the surface of the insulation to accelerate cross link procedure.

Insulation thickness	23℃, humidity 75%	35℃, humidity 60%	90℃ in water
0.9 mm	2-3 days	1-2 days	＜30 min
1.4 mm	5-7days	3-4 days	＜60 min
1.8 mm	8-10 days	5-7 days	＜90 min

Note:The above data were tested on the sample by squeezing film extrusion after mixing compound of A & B (at percentage of 95:5),double-sided exposure in the constant temperature and humidity box;the above value may differ from the actual cross link speed.

Q: Decoration when the purchase of water pipes, wires and other items included in the account: A lot of ways ah! You look at the back of the set-top box, a total of three kinds of interfaces, namely, HDMI digital signal (while transmitting audio and video signals), red and yellow and yellow chicken complex habit of glycosylation moxibustion slim faint handle (red is the right channel, white Is the left channel, the yellow is the video), the color difference signal (red, green and blue, only transmission video), S terminal (single hole four pin, only transmission video). You just put the video to the TV, the audio to the amplifier on the line. . if your amplifier does not have HDMI interface, then put the set-top box HDMI connected to the TV, the set-top box red and white two terminals, connected to the amplifier red and white input terminal, and adjust the amplifier to the appropriate channel The . if your amplifier has HDMI interface, then through the HDMI series on the line, the first amplifier or the first TV will do. . TV set after a lot of them, there is a group of AVOUT output interface, this group of red and white terminals connected to the power amplifier is also OK.

Q: If you want to sell wire and cable, then what to do in advance to detect? The The The The The: Line width, and can not pass the gap between the chip pins, even after, but also because the distance between the wire and the lead is less than the electrical rules specified in the safe distance. In general, the ground can not pass through the gap between the chip pins, go outside or take the gap between the two columns through the gap. The width of the ground wire can also be set appropriately, and the wire is widened by adding a polygon brass cut. The safety distance in the electrical rules defaults to 10 mils, which is relatively small, and the safety distance of the different networks should be set separately as needed.
