Release, Lubricant & Sizing
The MARCUS oxidized polyethylenes 3400 & 3500, when deposited on a substrate from emulsion, have inherent and highly efficient lubricating and release properties. These are harnessed as high performance components of processing aids in a number of applications.As release aids they are very effective in the die casting of Al, Zn and Mg alloys due to their high melting points and burning off features. They are also used in the mold release of polyurethanes and in the forming of concrete.
In the glass industry their lubricant function
plays an important role as a component of a treatment for the reduction
of breakage when newly formed thin walled and highly fragile bottles come
off the production line, there being a slippage action rather than an impacting
one when the bottles contact each other. The same lubricating efficiency
also applies in the treatment of glass fiber as it is produced. The application
of the polyethylene emulsion in this instance allows the fiber to be immediately
wound up without breaking.
