offers extended functionality!CAMPUS® datasheet | PLEXIMID® TT70
This datasheet of PLEXIMID® TT70 from Evonik Röhm GmbH is provided by the international plastics database CAMPUS.
CAMPUS is organized by a group of leading international resin producers, who have agreed to test their material according to uniform conditions, based on ISO standards (ISO 10350, ISO 11403), in order to offer comparable data to the market.
Productprofil:
PLEXIMID® TT70 is a highly heat distortion-resistant poly(n-methyl methacrylimide) (PMMI).
Besides showing the properties common to all PLEXIMID® molding compounds, such as
• excellent transmission and clarity,
• very high mechanical strength and rigidity,
• good weather resistance.
PLEXIMID® TT70 has the following specific characteristics:
• high stability of the optical characteristics at long-lasting thermal load,
• highest heat deflection temperature under load.
Application:
PLEXIMID® molding compound is particularly suitable for injection molding of items meant for applications that involve maximum thermal loads.
Example:
lenses, light guides, lighting fixtures, covers.
Processing:
PLEXIMID® molding compound can be processed on injection molding machines with standard 3-zone general purpose screws for thermoplastics.
Physical Form / Packaging:
PLEXIMID® is supplied as pellets of uniform size in aluminum-laminated, 25kg polyethylene bags.
