Dow Hyperlast has led the development
and supply of polyurethanes to the
filter industry for over 30 years, keeping
inline and ahead of the increasingly
stringent demands of this market.
Hyperlast™ elastomers and foams for
air and liquid filtration are extremely
versatile. There are no restrictions on
shape and so the polyurethane can fit
in awkward situations and difficult
environments and the materials have
exceptional tear resistance properties.
Processing costs are reduced as
these materials do not require hightemperatures
for moulding and
curing and the simple machinery
needed for processing polyurethane is
comparatively inexpensive.
HYPERLAST™ polyurethanes are used
as adhesives and sealants in filters to
adhere the element (usually pleated
paper) to the housing - the better the
seal, the more efficient the filter.
Also, HYPERLAST™ can be used to form
the housing. These efficient sealants
find their way into many applications
including dry cleaning, automotive,
vacuum cleaners, pollen filters and high
efficiency particulate filters (HEPF) for
clean room, high tech and
medical applications.
