TITLE:
Baymod ® A 52
TEXT:
Baymod ® A 52 is a highly effective modifier for
improving the notched impact strength and
processability of rigid PVC. If PVC modified with
Baymod A 52 is used to produce thin-walled
unpigmented articles, their transparency is
similar to those modified with standard MBS.
Used in combination with Baymod A 80 (bulk
SAN), Baymod A 52 can also be used to modify
halogen- and plasticiser-free semi-rigid
thermoforming film. A typical field of application
is decorative film for the lower part of vehicle
interiors where it is less exposed to light and
heat.

modifier in rigid PVC
Processing and compound properties
Blends of PVC and Baymod A 52 are prepared
and processed by the usual methods employed
for PVC. Processing aids are necessary, the
usual combinations of stabilisers and lubricants
being suitable.

After compounding in a high-speed mixer, the
dry blend can be processed straight away on
suitable equipment, e.g. twin-screw extruders.
For injection moulding and single-screw
extrusion, however, the processing of granules
has proved more suitable.
Rigid PVC modified with Baymod A 52 is
characterised by:
- very high toughness even with small
additions of modifier
- improved melting characteristics
- good surface finish
- good transparency and thermoforming of
film in comparison with standard MBS
modifiers.
Figures 1 and 2 show the mechanical
properties of laboratory compounds comprising
PVC and Baymod A 52.

2. Use of Baymod A 52 in semi-rigid,

Processing and compound properties
Blends of Baymod A 52 and Baymod 80, are
prepared and processed by standard methods
such as compounding in a plough-share mixer,
melting and homogenisation, such as in a twinscrew
extruder or compounder, and
thermoforming on a calender.
Usually, ABS film is imparted a surface decor
with the aid of a hot embossing roller (at
approx. 200 °C) and later processed into
moulded parts (e.g. glove compartment covers,
kneepads etc.) by thermoforming.
Film based on Baymod A 52 is characterised
by:
- outstanding processability on the calender
- good thermoforming properties
- good grain stability
- favourable price/performance ratio
- very good recyclability of, for example,
ABS moulded parts.
