Advantages of TPI

Super heat resistance: Working temperature can reach 240℃ (glass transition temperature: 250℃)

Good sliding characteristics: A low and stable dynamic friction coefficient and a low wear loss

Excellent cleaning characteristics: Gas exhaust and metal impurity content fall within an extremely small range

Stable performance in any environment: Excellent plasma resistance, radiation resistance, electrical characteristics, etc.

Superior dimensional stability: Stable coefficient of thermal expansion, good creep characteristics

TPI Injection Molding Conditions

Injection molding machine specifications: As the molding temperature will exceed 400℃, high temperature specifications are required. In addition, for GF and CF modified models, wear-resistant function is required. Long-term retention is easy to cause gelation, so please control the retention time within 15 minutes, and the injection capacity should be 20% larger than the maximum injection capacity of the injection machine. The shut-off nozzle will cause retention and therefore cannot be used.

Molding conditions: Please refer to the general injection molding conditions in another table for molding temperature and metal mold temperature.

Drying conditions: The pellets need to be dried under 200℃ or above 3 hours. Dehumidification and drying are recommended.

Cleaning conditions: Please use PEI (ULTEM) for cleaning materials before and after molding.

Gate and runner design: Please try to keep a certain thickness. Tunnel gates are not allowed.
