Thermal properties
Pre-drying recommendation:
Dryer type: dry air dryer
Temperature: 90°C
Drying time: 3 – 4 h
Residual moisture: <0.02
Temperature recommendations:
Melt temperature: 200 – 230°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 consult our application engineering department.
Dwell time on the machine:
Aim for short dwell time, empty cylinder when production is interrupted, lower temperature, flush with fresh material when restarting.
Post-treatment:
To achieve optimum service properties, tempering of the finished parts is required. This heat treatment can be carried out in a forced-air furnace.
Tempering recommendation:
Temperature: 100°C
Tempering time: 20 h
