Hot Melt Adhesive

Hot Melt Adhesive Manufacturer

Hot Melt Adhesive

Hot melt-type adhesives are solid polymer that transforms into liquid when heated. These adhesives typically have lower softening temperatures than other traditional glues. And when in liquid condition, they effectively bind specific application surfaces.

YASIN manufactures hot melt-type adhesives, available in different solid forms. That includes the following.

  • Blocks
  • Chips
  • Sticks
  • Pellets
  • Beads
  • And pillows

You can also request a suitable adhesive extraction design. Among the choices are roll-on, nozzle, or spray-style adhesive. And they always depend on specific purposes.

How It Produced

In the process of manufacturing, hot melt adhesives become malleable. Since they are thermoplastic plastics, the adhesive softens when heated and hardens in cooling. Additionally, there are specific materials for this process. 

The hot melt adhesives do not contain liquid; therefore, it’s heated to melt. Here is a list of what happens next, organized by stages.

  1. Transfer into the initial surface. 
  2. Then, it undergoes spraying, extruding, and other related methods. 
  3. It’s left out till the right amount of moisture and temperature.
  4. They will pull together once it reaches the optimal rate.

Hot Melt Adhesive Properties

Here are the properties of hot melt adhesives.

Viscosity

It’s the measure of liquid thickness and flowing resistance. The viscosity level of liquids affects their flowing motion per required application.

Peel

Peel calculates the amount of force needed to rupture a bond. They mostly employ pounds per inch units for two surfaces and various angles.

Molten Color

A number scale is employed to categorize the color of the hot melt. It involves quantitative, yellowness index methods, subjective procedures, and more.

Thermal Stability

Thermal stability shows the resilience of hot melt under different temperatures. It performs tests and assesses the change of velocity formation.

Softening Point

The softening point is when a hot melt begins to flow. Its key indicators involve the polymer’s transition temperature and including wax used. 

Mechanical

Mechanical is of the primary properties a hot melt has. It determines the yield point of stress applied. And a tensile strength for estimating the break force. 

Loop Tack

Generally used for hot melts in pressure-sensitive. They use ounces as a measurement to analyze how aggressive holt melt is.

Utilized Raw Materials

The raw material utilized for hot melt significantly affects their functionality and performance. They are generally made up of various materials, each with highlighted functions. For more overview of the details, consider the following. 

Polymers

Polymers are one of the typical constituents. They are responsible for the physical properties of hot melt adhesive. It’s a repetitive and long chain of specific molecules. 

  • High in viscosity
  • Heat and impact resistant
  • Flexible but durable

Resins

Resin control how long an adhesive will remain in liquid when being contacted with surface substrates. Therefore, they have a significant effect on the hot melt operation. 

  • It has many types
  • Faster drying speed
  • Optimal for larger amounts

Waxes

Waxes control the set speed and available time. In production lines, this combination of values works perfectly. 

  • Heat resistant
  • Largely determines the majority of characteristics.
  • Low-temperature adhesion

Plasticizers

Plasticizers are a second base to the polymer. They provide more flexibility and durability. Moreover, this material is well known for its low volatility.

  • Faster wetting
  • No odor
  • Lower melt viscosity 

Antioxidants

There are antioxidants used for adhesives. These are phenols, phosphates, BHT, aromatic amines, and more.

  • Protects the adhesive
  • Added with stabilizers
  • It prevents the material from degrading
