The development, production and marketing of high quality semi-finished products in form of bars
and tubes for the machining of sealing elements is an integral part of the core competence of Seal
Maker Produktions-u. Vertriebs GmbH. Due to our most modern manufacturing technology we are
able to cover the whole spectrum of seal applications. Our semi-finished billets, each of which is controlled several times before dispatch, are one of the most important components for our customers,
contributing to their competitiveness by offering high quality at a reasonable price. Besides the wide
range of standard dimensions which are carried on stock, special dimensions are also available within short delivery times in all materials and FDA-qualities.

Polyurethanes

Elastomers

Plastics

Special materials

Polyurethanes have gained a substantial importance in

modern seal technology. They hold a dominant market
share in the sector of rod seals and piston seals. Seal Makers Polyurethane semi-finished products stand out due
to their highest material quality. In many applications seals
made of Seal Maker Polyurethane outperform the service
life of seals made out of competitive manufacturers materials. The reason for this can be attributed on the one hand
to the careful selection of raw materials, and on the other
hand to the direct manufacturing technology. Unlike the
thermoplastic processed products, the cast semi-finished
products of Polyurethane billets made by Seal Maker have
the greatest degree of freedom to develop their physical
properties during polymerization. Any kind of negative influence during the polymerization process by heating up
and plastic deformation is avoided with our technology.
Besides the standard materials we also produce materials
with an optimized coefficient of friction, and materials for
direct contact with foodstuffs.
A further important fact is that Seal Maker semi-finished
products made of Polyurethane, up to a hardness of 95
Shore A, come with a clamping ring. This makes the use in
lathe machines a lot easier, and also independent from the
type of the production machine.

Elastomers, often referred to as rubber materials, are a

reasonable completion of the product range. Although they
got widely pushed out of many applications by the modern
Polyurethanes, the elastomer products remain important in
seal technology due to their wide spectrum of thermal and
chemical resistance. Seal Maker works exclusively with
rubber compounds made by internationally highly recognized batch manufacturers. This, in conjunction with Seal
Makers modern processing technology, is the guarantee
for well approved material compounds and an economical shaping. The resulting benefit for our customers is an
excellent price-quality ratio, and also prompt availability
of both standard and special dimensions and materials.
All Seal Maker semi-finished products made of elastomer
materials come in a hard shell, which makes them easy
machinable in CNC lathes, despite the low hardness and
high elasticity.

Hard plastics and fluorinated thermoplastics, as used for

back up rings and guide rings, as well as for special and
pre-loaded seals, complete the product range of Seal Maker semi-finished products. Seal Maker takes care that the
suppliers of these products fulfill the high quality requirements as set by ourselves and by our customers. The
excellent business connection we maintain with our suppliers, a broad product line, in combination with efficient
warehouse management, guarantee prompt availability.
Not only the dimensional range of semi-finished products is
well adapted to the requirements of machining, it is also the
wide variety of different material compounds which covers
all the requirements of seal application.

These semi-finished material billets are high quality plastic

products, produced solely by means of extrusion. The wide
choice of thermoplastic products is convincing: sheets, bars
and tubes are available in all important standard dimensions. Various material types are available in all standard and
intermediate sizes as well as with well defined tolerances.

Excellent wear, friction and extrusion properties
Resistance to almost all common chemicals

Back-up and guide rings, spring loaded seals
Mineral oils, HFC, HFD fluids, acids and dilute alkaline solutions, Sour oil and gas
Very low water absorption, excellent friction and wear properties
Applicable for contact with foodstuff

The indicated minimum application temperatures are thought as a general guideline, because a seals function
at low temperatures is dependent on the kind of the seal, the general application conditions, and on the kind of
the surrounding metal parts the seal is in touch with. The indicated upper temperature limits may be exceeded,
but this reduces the service life. Other materials available on request.
In case of doubt you are always welcome to contact our application engineers.
