Poly-forms Adhesive Films
Advantages to Liquid Adhesives

Inconsistent

Liquid adhesives can drip or smear onto unwanted areas of a component.

Consistent

Poly-forms are pre-shaped and remain flexible but intact until they are heated. The preformed seals allows adhesive to be located only on desired component features.

Poor Inventory Control

Liquid adhesives create poor inventory control. Operators have difficulty estimating the exact amount of adhesive required to accommodate a given batch of components. A large percentage of material is wasted by misdispensing, clogged needles, or operator error.

Simple Inventory Control

Poly-forms simplify inventory control. Determining the number of adhesive preforms required for a given batch is as simple as determining the number of required seals or bonds.

Slow Manual Dispensing

Manually dispensing liquid adhesives is time and labor intensive.

Rapid Manual Dispensing

Poly-forms can be manually dispensed at rates that far exceed manually dispensed liquids.

Expensive Automated Dispensing

Automated dispensing systems for liquid adhesives are often expensive and require extensive operator instruction. Most equipment is prone to clogging or pot life concerns. Constant adjustments for viscosity variations, clogs, and air entrapment require highly skilled labor to run and maintain dispensing equipment.

Affordable Automated Dispensing

Poly-forms are well suited for a variety of automatic or semi-automatic equipment. Templates, Pick & Place, and Bowl Fed Gravity Tracks are all practical methods for loading Poly-forms. Automated loading rates can range from 200 to 600 ppm, depending on loader, component, and Poly-form design.

Difficult Removal

Once liquid adhesive is dispensed, it cannot be easily removed from unwanted areas. As it starts to gel, reworking becomes increasingly difficult.

Simple Pre-Melt Removal

Un-melted Poly-forms are easily removed from components, allowing for greater flexibility and reducing the number of scrapped parts.

Messy Cleanup

Liquid adhesive usually requires extensive cleanup procedures, including the use of toxic solvents and the disposal of adhesive waste.

Simple Cleanup

Poly-form adhesive films require little or no cleanup procedures. Cleaning is as easy as collecting the unused preforms.

Costly

Expensive dispensing equipment, time-consuming procedures, skilled labor, wasted adhesive, scrapped components, and product returns add high expenses to liquid adhesive dispensing.

Cost Effective

Affordable loaders, inventory efficiency, reduced labor, minimal or no scrap, and product return prevention minimize the hidden costs often associated with liquid dispensing.

Variable Quality

Liquid bond paths vary in shape, size, and location, causing variations in performance and quality. Adhesive drips on critical component areas jeopardize product performance.

Precision Quality

Tight dimensional tolerances and viscosity consistency ensure repeatable, high-quality seals. Precise, consistent results contribute to product quality
