Who is the winner in the market? MPO or EVA Hot Melt Adhesive?
May 3, 2021
MPO and EVA series hot melt adhesives, what is the difference?
TEX YEAR leads you to this century competition and helps you clarify everything once and for all.

Comparison of advantages

Ethylene vinyl acetate (EVA)Metallocene polyolefin (MPO)
Commonly used basic polymerWider operation temperature range than EVA
  • The type and quantity of wax and resin controlling the clotting time and stickiness
  • Lighter color and less odor
  • Filler allowed under specific conditions
  • Good thermal stability
 
  • Quick operation setting
 
  • Lower density
We have complete EVA production lines for our “TEX YEAR” products. The adhesive strips and packaging glues, in particular, are in a leading position in the industry.Products in response to the development trend of the international and domestic markets are also produced under the brand name “TEX YEAR.”

Comparison of properties

The Proportion of MPO and EVA is 0.90 and 0.98, respectively. Though the weight of both adhesives are same, MPO is bigger, has higher mass and, thus, more usable adhesive amount, making it more advantageous in this respect.

When comparing under the same conditions, the experiment proved that MPO hot melt adhesive can be applied to 4 more pieces than EVA!!
  • Total application weight: 10gram
  • Application thickness/piece: 40mm
  • Operation temperature: 160℃~180℃

Comparison of strengths


In fact, both EVA and MPO hot melt adhesives can meet the strength requirements of the customers. However, the specific weight, density, and volume of the MPO adhesive as well as the same strength with less MPO than EVA enable a saving of 10~20% use amount of the MPO adhesive in comparison with the traditional EVA adhesive. This is obviously an outstanding advantage of the MPO hot melt adhesive.

Comparison of shapes

In addition to the properties and advantages, neat and clean shapes are required to make the first impression. This is more the focus of MPO than EVA. The arrangement of the MPO hot melt adhesive is more neat and tidy. It is relative not stringy and, thus, can produce more beautifully shaped finished products to sell at a higher price.

Comparison of durability

MPO hot melt adhesives have much higher stability than EVA. This is demonstrated in the following experiment.
During a prolonged durability test at 180℃ for 24, 48, 72, 96, and 148 hours, the MPO series products show a thermal stability much better than EVA as illustrated in the figure below. The yellowing effect of the MPO adhesive in the aging process is much lighter than EVA. What an outstanding performance of MPO!

The MPO hot melt adhesive seems to become the only focus after a series of 5 tests, but, in fact, the EVA hot melt adhesive also performs very well in many respects. It surely has special advantages and features to stand on the top of similar products for such a long time.

The EVA hot melt adhesive has been on the market for many years. It is highly acceptable, has a wide range of applications, and is sold at a lower price. Most important, it does not require repurchase or replacement of equipment or resetting of parameters. It has better compatibleness than the MPO hot melt adhesive. Honestly, both of them have their own advantages. It is suggested to select the products depending on your requirements to ensure choosing most suitable products that can produce the best results.

We have complete production lines and professional supports for our TEX YEAR products. No matter whether you need innovative MPO or traditional EVA series hot melt adhesives, just “stick to Tex Year!”.
