Introduction

Cleanroom synthetic gloves have been used in the critical environments of the electronic, disk drive,

semiconductor as well as storage media industries, for the past 15 years. The quest for a cleaner glove,

in new emerging industries of TFT, LCD, nanotechnology, bio medical applications, has ensured that

this is a growing market. The industry use of cleanroom gloves is currently dominated by synthetic

gloves, though, this wasn’t the case, right up to the year 2000, wherein, latex gloves was the principle

cleanroom available.

The basic function of cleanroom gloves is to ensure minimal transfer of contaminants onto the products

or components being processed or manufactured in a clean environment. Such contaminants will

always be present in the exposed hands of the personnel. It is for this purpose that the hands need to be

gloved. However, such gloves need to have minimal contaminants on its surface, thus the need for the

use of cleanroom gloves.

The principle contaminants that could compromise the quality or the integrity of the product or process

in a critical environment are sub-micron particles, ionic chemical contaminants, non-volatile chemical

components as well as silicone, amide or dioctyl phthalate (DOP). In the cleanroom industry, these

parameters a
