Product Description
UnderStencil is a hydroentangled blend of 54% cellulose / 46% polyester
wipe that can be used in a variety of manufacturing applications and
cleaning processes. A multipurpose, micro-level cleaning material, made
from Sontara®, that is specifically engineered for cleanroom applications.

Hydroentanglement:
Hydroentanglement also known as spunlacing, entangles the fibers to givestrength to the web. It uses fine, high-pressure jets of water to strike a  web to intermingle the fibers, resulting in the bonded fabric being a nonwoven.
Nonwovens made by this method have high fabric integrity.

Electronics:

medium, with or without solvents, from stencils, screens, PC boards,
squeegees, tools, fixtures and production equipment. Understencil wipes

are manufactured from the same fabric as our SmartRolls® 4000 Series
Understencil Wiping Rolls and 401PW SelectaWipe Rolls.
