Environmental impact
Stamylan® UH and its packaging is safe for
humans and the environment. For disposal, Stamylan® UH can be recycled as a
base material for less demanding applications or may be safely put in
landfills as an inert material. CO2 and H2O are the only reaction products
when Stamylan® UH is incinerated under controlled conditions.
Note: Additional national or regional provisions may be in force within this
matter. Please consult the appropriate authorities in your area.
Processing
Due to its high melt viscosity, some traditional
plastic processing techniques for polyethylene are unsuitable for Stamylan® UH.
Stamylan® UH can be processed via compression moulding and ram extrusion.
Using these techniques, semi-finished products such as (large) sheets, rods,
tubes and a variety of extruded profiles can be manufactured. Most finished
articles of Stamylan® UH can be made by conventional machining techniques such
as: sawing, planing, drilling, milling, punching and turning.
An extremely high melt viscosity also enables easy processing into porous
parts by pressure-less sintering and gel processing can be used to process
Stamylan® UH into sheets and membranes for e.g. battery separators.
While it is virtually impossible to improve upon the material’s wear
resistance and impact strength, other properties of Stamylan® UH can be
enhanced by incorporating additional pigments, additives or fillers—when
homogeneously mixed prior to processing. However, it must be noted that
modifications made to satisfy application requirements, may alter other
properties of the material.
