3 When they are added to agricultural PVC/ PE/ EVA films, heat-retaining property of these films is FT-IR spectra is PE films with wt% HT-P and without is treated the surface by higher fatty acid, and the median particle size is about m . Therefore, HT- series is mixed with films Information7 Application for Neutralization AgentFeaturesCompared to calcium stearate which is used as neutralization agent too, HT-P is effective at low doesn t cause problems in using calcium stearate(bleeding of stearic acid, moisture absorption by CaCl2).Evaluation of the degree of inactivation of residual acid materialsLess change of weight of iron test pieces (by oxidation) shows higher neutralization (non-stabilized PP)HT-PCalcium StearateAddition amountppm 1003005001000 Weight before after of of test pieces
