AFFINITY™ GA

Polyolefin Elastomers

More Mileage for your Hot Melt Adhesives

High performance. A phrase heard often but too often not fully realized. The family of AFFINITY™ GA Polyolefin Elastomers (POEs) provide performance well beyond the norm for everyone along the value chain.

AFFINITY™ GA Polyolefin Elastomers include a range of polymers based on proprietary technology from Dow. They offer performance, processing, and end-user advantages over incumbent technologies such as EVA (ethylene-vinyl acetate) formulations.

AFFINITY™ GA polymers reliably stick boxes and other substrates together over a broad range of temperatures, while greatly enhancing the efficiency in doing so – achieving more adhesion, using less adhesive! And along the way, with added benefits such as reduced odors and gelling, less machine wear and tear, and better color in use, everyone wins.

AFFINITY™ GA POEs offer diversity for a variety of adhesive needs

Scientists in lab

AFFINITY™ GA POEs are characterized by novel chemistry that combines high flow, low crystallinity, and low molecular weight. The one-of-a-kind balance of AFFINITY™ GA POEs allows processors and formulators to achieve:

  • Hot melt adhesives (HMAs) formulations that stick better
  • Blends that are more flexible and durable
  • Longer pot life for less downtime

Manufacturers require easy-to-process and cost-effective components. AFFINITY™ GA polyolefin elastomers can help address both needs. They enable hot melt adhesives (HMAs) that offer:

  • High-performance adhesion across a wide temperature range
  • Outstanding processability
  • Low taste and odor transmission
  • Colorless formulations
  • Less plugging and clogging for reduced downtime

Brand owners and their packagers appreciate the ease in use, aesthetics, and economies offered by AFFINITY™ GA polyolefin elastomers:

  • Exceptional sealability, with high hot tack and low heat seal temperature
  • High green strength (Tack) and rapid set during compression cycle enabling high line speeds and reduced waste
  • More powerful bonds across a wider range of service temperatures for increased versatility
  • Stable viscosity - Excellent control of viscosity resulting in precise control of bead size and bead placement
  • Less plugging and clogging for reduced maintenance and downtime
  • Excellent optics; water white formulations and color stability
  • Greater sealing mileage per pound
  • Reduced adhesive usage, lowers cost as much as 15-40% (depending on application)

When it comes to products and their packaging, consumers demand high performance in the form of dependable and consistent seals. Adhesion that stays firm where it must, while allowing easy opening of packaging.

Advantages for many applications

Not a packager? Not to worry. AFFINITY™ GA polymers offer advantages for other hot melt applications, including many of the same efficiencies enjoyed by the packaging value chain. Discover their uses in:

Choices make a difference

The polymer of a hot-melt adhesive formulation determines the choice of the other raw materials. There are currently four AFFINITY™ GA polymer grades available to better help in matching adhesive requirements to a specific formulation:

Make your best choice

AFFINITY™ GA POEs are versatile polymers designed to help your applications flow faster, flex longer and stick better. Combining high flow with low crystallinity, these raw materials allow you to reach higher levels of performance, processing ease, and value in polymer modification/compounding and hot melt adhesive applications.
