2 Tested under artificial weathering according to DIN EN ISO 4892-2. The black compounds (TCxMLZ) are weather resistant up to 2200 MJ/m 2 ,
which is equal to 1.1 year outdoor expose in central Europe
3 Deviating from ISO 37 standard test piece S2 is tested with a traverse speed of 200 mm/min.

peel force (N/mm) x
CO/1VT Series – Adhesion to PC, ABS
THERMOLAST ® K
MATERIAL ADVANTAGES:
excellent adhesion in coinjection moulding
(depending on geometry and processing)
insert moulding is possible
natural compounds easy to colour
tactile surface (soft touch)
good flow characteristics
wide hardness range 32 – 80 Sh A
UL 94 HB listed
PROCESSING:
processing on 2K injection moulding machines
(many grades also for insert moulding)
mould temperature: 40° C – 60° C
low back pressure
high shear force (small injection point, high injection
rate etc.) is beneficial for the flow behaviour
pre drying for 2 – 4 h with 60° C - 80° C is
recommended
processing temperature:
adhesion to engineering thermoplastics
180° C – 240° C (max. 250° C)
high injection speed and pressure
Description peel test (according to "Renault D41 1916" standard)
In the below represented test setup the peel force is measured by a tensile testing machine in N/mm in dependence
of the path, the upper cramp of the tensile testing machine puts back. This pass is called peel path. Therein the
stretching proportion of the TPE is contained.
Test piece dimensions: Thermoplastic part: 130 x 22 x 2 mm, TPE part: 130 x 20 x 2 mm.
