Don't Fear the Filler in Transparent Lamination Products
It used to be a general rule: if you want transparency in your lamination film,
you stay away from fillers. In other words, if you want the best clarity
- you pay for it.
But you have another option - HIFILL N (nepheline syenite) is the filler
that will reduce formulation cost without sacrificing contact clarity.
In addition to HIFILL N's superior contact clarity,
this functional filler offers additional advantages.
Extended durability as result of superior photochemical stability and improved color fade resistance relative to calcium carbonate and talc.
HIFILL N has been used to improve scratch and mar resistance.
No reportable free crystalline silica, improved industrial hygiene, safer solution - does not require silica-related labeling; FDA-approved for up to 50% by weight in the final product.
Chemically inert, allows synergy with other additives. As a result, customers are able to achieve optimal formulation designs.
Transparent, color neutral which allows for optimum usage of darker pigments and helps with pigment dispersions.
HIFILL N is made of nepheline syenite, which is a unique all-natural sodium-potassium alumino silicate mineral that is silica deficient. This mineral is responsibly mined from one of the largest and most consistent high-purity ore reserves located in Blue Mt. Ontario Canada. HIFILL N additives are available in ultrafine, precisely controlled particle size distributions for optimum performance. HIFILL® N allows for formulation and processing cost reduction while not adversely impacting the products’ physical properties and durability.

Here, in our lab, we continue to expand the knowledge base of nepheline syenite, microcrystalline silica, and air-floated kaolin to prove the technical advantages of our functional fillers compared to other minerals and to further your plastic product proficiency.
OPTIMIZE FORMULATION COST WITH GREATER ADDITIVE PERFORMANCE
Chemically inert, nepheline syenite offers superior performance and longer service life in demanding applications with reduced formulation cost. Nepheline syenite’s synergy accepts a lower amount of expensive UV stabilizers, lubricants, heat stabilizers, and other additives, saving money.
The lower oil absorption could also translate into minimal interference with other additives. The unique combination of low oil absorption and particle morphology enables higher loadings in masterbatches.
The transparent, color-neutral functional filler supports color extension in pigment dispersions. Outstanding purity and low tint strength preserve colorant integrity while heightening pigment dispersion. Lower pigment loading can be achieved while maintaining the same color strength to reduce formulation cost further.
- Formulation cost savings could be enabled by its transparency and low oil absorption
- Does not interfere with other additives
