Processing Guide

Drying:
Under general storing condition,
T BLEND â 4000 20N can absorb moisture, so pre drying is necessary before
processing. If the environment is humid or surface performance parts are required, please dry the pellets in hot
air circulating oven/hopper (50 o C) for 1 2 hour.
Molding
The process is same as EVA foaming but it needs higher DCP volume (0.2~0.25phr) than EVA foaming.
Processing Temperature
Mixing at 120
℃℃→ loading DCP / AC at 100 → taking out at 95
Others:
Press molding at
165 ℃℃~168 ℃℃, 1 mm thickness needs 85 ~ 90
