Antiblock EcoBloc P-3 Antiblock Additive for Agricultural Films

It exhibits strong infrared reflection properties in the 1400-700 cm-1 wavelength region to reduce heat loss by as much as 74% 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, it will not interfere with HALS type stabilizers nor absorb other process additives. Precise partide size control ensures that it will not adversely impact tensile strength or other film mechanical properties. Chemical purity, including low iron and transition metal content, minimizes catalyzed photodegredation to extend field service lifetimes.

It is defined regulatory- wise as GRAS ( Generally Recognized As Safe ). So no OR is needed as the item is in fact exempted from REACH. (Relevant in Europe). We also work on a FDA statement.

The process of the Feldspar is done by mechanical procedures only. No coating or additives.

Ecobloc P-3 is a high-quality Silica Aluminate crystalline powder engineered to deliver superior optical and thermal performance in greenhouse films, ensuring maximum plant growth and energy efficiency.

Optical Excellence & High Loading

Ecobloc P-3 is uniquely designed with a precisely matched refractive index to the host polymer, virtually eliminating light scatter and maximizing the transmittance of Photosynthetically Active Radiation (PAR) essential for accelerating plant growth. This sophisticated optical engineering allows film producers to break the conventional 10% filler loading barrier while maintaining Total Light Transmittance (TLT) above 90%, a level of clarity that sets it apart from standard fillers. It is formulated to be highly effective across single resin, copolymer, or blended LDPE, LLDPE, or EVA horticultural film systems.

Thermal Retention & Cost Savings

This powder offers an exceptional solution for heat management through its strong, targeted infrared (IR) reflection properties in the 1400 - 700 cm -1 spectrum. Ecobloc P-3 achieves a proven heat loss reduction of up to 74% compared to unfilled films. This superior energy retention elevates night temperatures to the optimal growth range, significantly extends the profitable growing season, and drastically reduces reliance on supplemental space-heating, delivering a rapid return on investment.

 Film Durability & Purity

Ecobloc P-3 is built on a non-reactive chemical platform and features an inherently low surface area. This design prevents it from interacting with or absorbing critical film additives like HALS-type stabilizers, thereby preserving the intended long-term durability of the film system. Through strict, state-of-the-art particle size control, the product ensures zero detrimental effect on key mechanical metrics such as tensile strength. Furthermore, its ultra-high chemical purity (e.g., extremely low transition metal content) minimizes the risk of catalyzed photodegradation, which is crucial for maximizing the film's field service lifespan.

Clean & Compliant

The source Feldspar material is processed using solely mechanical purification methods, ensuring the final product contains absolutely no chemical additives or surface coatings. This commitment to purity means Ecobloc P-3 is classified as GRAS (Generally Recognized As Safe) and qualifies for an exemption from REACH registration (EU). An FDA statement affirming its compliance is currently pending.
