HIGH-CLARITY ANTIBLOCKING ADDITIVE

A unique and distinctive combination of particle morphology, surface chemistry and refractive index, MINBLOC HC additives deliver excellent antiblocking performance, superior haze, gloss and clarity values in packaging grade flexible films without diminishing critical structural or mechanical properties.

MINBLOC HC additives are chemically inert, non-absorptive and compatible with polymer additives which optimizes the performance of slip, antioxidants, stabilizers, colorants and other processing aids. Suitable for either masterbatch compounding or direct additions to film grade resin systems, MINBLOC HC is easy to handle and disperse which translates into higher throughput.

All MINBLOC HC grades are processed and refined with rigid adherence to QIPSM and/or ISO 9001 quality assurance programs.

HORTICULTURAL FILM THERMAL SERIES

With a refractive index that essentially matches that of LDPE, LLDPE or EVA resins used for horticultural films, MINBLOC® HC additives maximize transmittance of photosynthetically active radiation (PAR) to accelerate plant growth. Total light transmittance of MINBLOC HC-containing films remains above 90%, even beyond 10% loading.

MINBLOC HC additives exhibit strong infrared reflection properties in the 1400 – 700 cm-1 wavelength region to reduce heat loss by more than 70% compared to unfilled systems. This retained infrared energy increases night temperatures for optimal growth, extends the growing season and reduces space-heating requirements.

Due to its low surface area, low porosity and a non-reactive chemistry, MINBLOC HC additives will not interfere with light stabilizers nor absorb other process additives. Precise particle size control ensures that MINBLOC HC additives will not adversely impact tensile strength or other film mechanical properties. Chemical purity, including low iron and transition metal content, minimizes catalyzed photodegradation to extend field service lifetimes.
