MINBLOC® HC High-Clarity Antiblock additive, which is nepheline syenite, is produced from one of the largest and most consistent high-purity ore reserves located in Blue Mt. Ontario Canada. A unique all-natural sodium-potassium alumino-silicate mineral that is silica deficient by mineralogical classification does not require any silica-related labeling.
High Clarity Grade Antiblocking Additives
- 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. At night, due to strong infrared reflection properties, MINBLOC® HC captures and retains thermal energy by reflecting much of the heat back into the greenhouse. This retained thermal energy increases night temperatures inside the greenhouse for optimal growth, extends the growing season and reduces space-heating requirements.
- 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.
- Product Advantages
- Industry's best clarity and lowest haze values - With a refractive index that is nearly identical to that of most polymer resins, MINBLOC® HC operates transparently within the polymer mix without diminishing critical structural or mechanical properties.
- Excellent antiblocking performance - MINBLOC® HC deliver an excellent balance in both antiblocking and optical properties.
- Narrow particle size distribution - Easier to handle and allows for higher masterbatch loadings.
- Enhanced thermicity in agricultural films - Accelerates growth by transmitting greater amounts of photosynthetically active radiation (PAR) and reduces energy cost by retaining more heat inside the greenhouse compared to other mineral IR absorbers.
- Enhances crop protection - Optimizes growth with minimal fluctuations in temperature.
- Extends film service life - Non-reactive chemistry with low iron minimizes catalyzed photodegradation.
- Double classification creates a unique narrow particle size distribution.
- High loadings possible with stable melt index (MI) because of almost no fines.
- Lower oil absorption - Chemically inert, allows synergy with other additives. As a result, customers are able to achieve optimal formulation designs.
- Regulatory compliance - FDA-approved for up to 50% by weight in the final product. No reportable free crystalline silica, does not require silica-related labeling.
