 For the
manufacture of molded parts made of polyurethane, Baydur ® of the Bayer
AG is used at Thieme in different material specifications.
Baydur ® 66 FR is the ideal material to realize different wall
thicknesses and densities. In addition, the combination of massive edges
and micro porous cores can be realized. The manufacture of molded parts
of different sizes and dimensions is carried out as a sandwich
structure.
Products made of Baydur ® 66 FR excel through an optimal relationship of
stiffness, stability and weight. A high degree of design stability can
even be realized in filigree areas. Different wall thicknesses (5-30 mm)
are also possible with Baydur ® 66 FR without sink marks. The average
wall thickness is approx. 10 mm. Complicated three dimensional parts,
even with long flow paths can be manufactured without issue. The
insulation properties for noise and temperature are benefits of the
material Baydur ® 66 FR. The integration of functional contours and
elements is possible without issue. At low and medium annual part
quantities, economical manufacturing of molded parts is possible . The
material Baydur ® 66 FR is used in enclosures, housings and covers which
require and aesthetic external design and functionality internally.
Baydur ® 110 FR is the polyurethane system which is used by Thieme for
thin wall parts. Despite the thin-walled property, the produced part is
very impact resistant. With Baydur ® 110 FR, dimension and wall
thickness relationships are realized which were considered impossible in
the past. The result is a thin wall, compact and homogenous structure
which has a filigree molded part appearance similar to thermoplastic
parts and still retains its impact resistance. The average common wall
thickness is between 4-6 mm. Thieme uses the material Baydur ® 110 FR
for large surface and strong covers with long flow paths. In comparison
to other manufacturing processes, these parts can include all the
necessary holes, foldings and stiffness ribs within one process.
Locating, bracketing and fixing elements can also be molded in. |

Baydur ® GS is a material which is used in a casting process and is
found where high mechanical and chemical resistance is required. Parts
are produced which include a high impact resistance, stiffness and
thermal stability. Another advantage is the high chemical resistance and
an especially good decomposition resistance. The material Baydur ® GS
makes it possible to manufacture wall thicknesses between 4 and 100 mm.
economically, as even with very high wall thicknesses the molding cycle
is relatively short. The light weight of the parts made of Baydur ® GS,
the corrosion resistance and the impact resistance are advantages which
fit together with the price performance ratio. As relatively low
investments are necessary for molds, Baydur ® GS is used mainly for
highly stressed functional parts and can be found increasingly as a
substitute for metal castings of aluminum, zinc or steel.
