Features
Compared to calcium stearate which is used as neutralization agent too, HT-P is effective at low doses. HT-P 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 materials
Less change of weight of iron test pieces (by oxidation) shows higher neutralization effect.Unit Blank

Technical Details & Test Data
- Heat-Retaining Property
Heat-Retaining Property
Hydrotalcites have infrared-absorbing ability. When they are added to agricultural PVC/ PE/ EVA films, heat-retaining property of these films is increased. Right-hand FT-IR spectra is PE films with 6.5 wt% HT-P and without HT-P.
Excellent Transparency
The reason is that the refractive indexes of hydrotalcites are almost as same as films itself, 1.5 .
Good Dispersibility
HT-series is treated the surface by higher fatty acid, and the median particle size is about 0.5 mm . Therefore, HT-series is mixed with films well.
