The world's first conductive aramid fiber base , both the meta-aramid flame retardant high temperature properties and electrical conductivity, is a broad application prospects of new materials , specific performance is as follows:
1 superior flame resistance
Thailand Mita conductive fibers limiting oxygen index LOI greater than 28% , not spontaneous combustion in air , melting or droplet generation , releasing toxic gases , carbonization starting temperature of 400 ℃.
(2) excellent heat resistance
At 190 ℃ working conditions long-term use , the fiber conductive properties remain stable.
As shown, the base material itself as the degree of difference in temperature , Thai Metal conductive fibers and conductive fibers compared to other substrates ( such as polyester conductive fiber ) , exhibit excellent high temperature properties. Can be seen from the curves , Thailand Mita conductivity of conductive fibers at 270 ℃ the following basic does not produce significant changes in the temperature rise at 275 ℃ conductivity began to fall , showed a better temperature performance ; the polyester base the conductivity of conductive fiber material at temperatures up to 220 ℃ when it began to gradually deteriorate as the temperature rises , when the temperature rises to above 230 ℃ , the fibers begin to bond and thus can not be used.
Shown in Thailand Metroplex conductive fibers and polyester -based conductive fibers placed at 265 ℃ under the conditions obtained after 5 minutes before and after pictures, it is clear that Thailand through pictures Mita conductive fibers placed around the fibers at high temperature state of no significant change, while polyester -based conductive fibers have shown a significant decline , some had melted . High temperature conductive fibers after Thailand Mita resistivity remains at 104Ω · cm, while the polyester -based conductive fibers have been unable at this time to continue to use .
3 excellent conductive properties
The current conductive fibers mainly polyester, polypropylene, acrylic, nylon and other traditional fibers blended or composite substrate or conductive fiber preparation , the uneven quality of its products . On the whole , the majority of conductive fibers currently used mainly matrix material is nylon and polyester , nylon 6 a foreign conductive 3D-51-931 ( gray ) a specific resistance of 2.85 × 108Ω · cm, Thailand Mida gray conductive fiber specific resistance can be up to 5.8 × 107Ω · cm; abroad a conductive fiber polyester 3D-51-B31 ( black ) 3.92 × 105Ω · cm, Thailand Mida black conductive fiber was 3.7 × 104Ω · cm.
4 good mechanical properties
In mechanical properties , the fibers can be processed into any length , and feel soft, in the conventional textile weaving machine . Conductive fibers with other mechanical properties of comparison , it was found that Thai Mita lower conductive fiber fineness ( product range up to 1D ~ 5D), and the fibers have better physical and mechanical properties , more suitable for the textile field .
It should be noted that the test samples are first used Bozzetto Cinscoure PS at 70 ℃ for 15 minutes and then dyed at 130 ℃ for 60 minutes, and finally with Cinfast EF detergent for 15 minutes at 70 ℃ .
