PTFE tubing is Exellent operating performance is as following :
* High pressure resistance its long term using temperature is 200 - 260 degree
* Low presure reisitance it still keeps soft under 100 degree
* Corrosion resistance it can bear the aqua regia and all organic solvent
* weatherimg resistance best ageing lifetime among all plastic materiais
* High lubricating lowest coefficient of friction among all plastic materiais (0.04)
* Non-stick lowest interfacial tension between all solid materiais and not stick
* Nonhazardous physiological lnert
* Excellent electric property the ideal insulating material of C Grade

| ## PFA-HG semiconductor high-grade tubing is made from the Dupont 451HP-J with lower level fluorine ion and | ||
| reduction of spherical size of the crystallization structure. The surface of the wall is flatter and | ||
| smoother. PFA-HG semiconductor hogh-grade tubing is suitable for high purity application | ||
| In addition too the normal characteristics of PFA tubing. PFA-HG tubing has the following characteristics | ||
| > Smoother intersurface bore (RT=0.2um) | ||
| > Reduction of residual particles and liquid | ||
| > Reduction of cleaning time | ||
| > reduction in elution of liquid | ||
| > Improvement in transparency of tube wall | ||
| > Improvement in elution of fluoric ion | ||
| > Improvement of crack tolerance under harsh envirnment | ||
| Features : | ||
| * Improved surface flatness reduces entrapment of particles or liquids | ||
| * Enhanced stress crack resistance (i.e. fuming sulfuric acid) | ||
| * Lower liquid or gas permeation | ||
| * Reduced cleaning time | ||
| * Improved dielectris strength | ||
| * Minimal extactable fluorine ion | ||
| * Improved clarity |
| * Maximum usage Temperature : 260 c |
