Pre-drying recommendation:

Dryer type: dry air dryer
Temperature: 90°C
Drying time: 3 – 4 h
Residual moisture: <0.02

Temperature recommendations:

Melt temperature: 215 – 235°C
Mold temperature: 20 – 50°C

Due to its special properties, KEBAFLEX / U may tend to stick to smooth and polished mold surfaces. Structured surfaces favor the demolding behavior. Alternatively, the mold can be provided with suitable coatings. Please ask our application engineering department for more information.

Post-treatment:

To achieve optimum service properties, the finished parts must be tempered. This heat treatment can be carried out in a forced-air furnace.

Tempering recommendation:

Temperature: 100°C
Tempering time: 20 h
