Principle
DuPont Tyvek is a registered trademark of DuPont proprietary’s protective material brands. It makes use of flash distillation technology: the polymer is processed into continuous filaments by hot-melting, then forms high-density polyethylene after thermal bonding. Using this unique technology we can produce very tough materials with pretty light weight. Tyvek series products combine the benefits of paper, film and fiber as a whole, provide with properties such as tough, durable, strong anti-puncture, anti-static & dust-free, Moreover, their control wet working time is from 60 to75 days.
Scope of Applications
Available for electronic components, glass lenses, semiconductor packaging & testing, medical supplies & health care products, bio-chip and so on.
According to
U. S. Military Standard (MIL-D-3464E), Japanese Industrial Standard (JIS-Z-0701) and German Industrial Standard (DIN-55473).

◇High puncture resistance——good protection for the montmorillonite clay inside.
◇Good water resistance ——Because the Tyvek is made of PE, so even being damp or soaked, the technical strength won’t change
◇Good breathability——make sure that the desiccants can absorb moisture fully.
◇Excellent chemical resistance —— It’s lack of reaction with most strong acid, alkali & salt.
◇Antistatic surface treatment——dust-free, no foreign matters on the surface.
