Tyvek-mont clay desiccant

Hotline£º0512-63316901

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 light weight but very tough materials. 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, and their control wet working time is from 60~75 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).

¡óHigh puncture resistance¡ª¡ªgood protection for the mont-clay or silica gel inside.

¡óGood water resistance ¡ª¡ªBecause the Tyvek is made of PE, so even damp or soaked, the technical strength won¡¯t change

¡óGood breathability¡ª¡ªmake sure that the desiccant can absorb fully.

¡óExcellent chemical resistance ¡ª¡ª It¡¯s lack of reaction with most strong acid, alkali & salt.

¡óAntistatic  surface treatment¡ª¡ªdust- free, no foreign matter on the surface.
