Product Information
Polystyrol 466F
Jun. 2006
Product description
Polystyrol 466F is normal flow, very high impact polystyrene with a good heat
resistance and a high stiffness. It can be used for both injection molding and
extrusion molding application.
Processing
Polystyrol 466F can be injection molded under different conditions depending on
o
machinery available and articles molded. Melt temperature should not exceed 280 C.
Applications
Consumer electronics: TV-front and back; chassis for VCR and CD player.
Household : internal parts of vacuum cleaners; air conditioner; drawers
Audio and video, telephone ; printer housings, keyboards, computers, copier parts.
Bobbin sleeve
Form supplied and storage
Polystyrol 466F is supplied as cylindrical shaped granules and is supplied as 2 types
according to external lubrication, GR 2 (no external lubrication) and GR 21 (external
lubrication). It has to be kept in its original containers in a dry, cool place. Avoid direct
exposure to sunlight. Polystyrol 466F can also be stored in silos.
Food legislation
If used unmodified and under appropriated processing conditions Polystyrol 466F
conforms with FDA Title 21 CFR Section 177.1640 regarding the use of polystyrene
in food contact articles.
Product safety
During processing of Polystyrol 466F small quantities of styrene monomer may be
released into the atmosphere. At styrene vapor concentrations below 20 ppm no
negative effects on health are expected. In our experience, the concentration of
styrene does not exceed 1 ppm in well ventilated workplaces 鈥? that is where five to
eight air changes per hour are made.
Note
The statements in this document are based on our present technical knowledge and
experience. They do not relieve processors of the responsibility of carrying out their own tests,
and purchasers of our products are expected to carry out receiving inspections. Neither do they
imply any binding assurance of suitability for a particular purpose. Any proprietary rights should
be respected and existing legislation observed.
