How to Calculate Polyethylene Wax Amounts for Adhesives (Hot Melt Adhesives, Pressure-Sensitive Adhesives)

General Approach to Calculating Polyethylene Wax Amounts in Adhesives

When formulating adhesives, particularly hot melt adhesives (HMAs) and pressure-sensitive adhesives (PSAs), determining the precise amount of polyethylene wax is critical. This wax impacts the viscosity, heat resistance, and crystallization behavior of the adhesive. Below is a detailed approach for calculating the required polyethylene wax amounts for these types of adhesives.

Hot Melt Adhesives

Hot melt adhesives are composed of a base polymer, tackifiers, waxes, and additives. Here’s a step-by-step breakdown of the formulation and calculation:

Formula Calculation:

1. Base Polymer Content (B): Typically 30-60% of the formulation.
2. Tackifier Content (T): Usually 30-50%.
3. Wax Content (W): Polyethylene waxes typically constitute 5-15%.
4. Additives (A): Includes antioxidants, stabilizers, etc., usually 1-5%.

The general formula for hot melt adhesives is: Total Adhesive = B + T + W + A

For a typical formulation, if:

• Base Polymer = 50%
• Tackifier = 35%
• Wax = 10%
• Additives = 5%

The amount of polyethylene wax (W) can be calculated as: W = (10/100) * Total Adhesive

Practical Example for Hot Melt Adhesives

For a 1000 g batch of hot melt adhesive:

• Base Polymer: 500 g
• Tackifier: 350 g
• Polyethylene Wax: 100 g
• Additives: 50 g

Pressure-Sensitive Adhesives

Pressure-sensitive adhesives need to remain tacky and adhere under light pressure. The components are similar but often in different ratios.

Formula Calculation:

1. Base Polymer Content (B): Ranges from 40-60%.
2. Tackifier Content (T): Ranges from 30-50%.
3. Wax Content (W): Typically 5-10%.
4. Additives (A): Usually 1-5%.

For a typical formulation, if:

• Base Polymer = 55%
• Tackifier = 35%
• Wax = 7%
• Additives = 3%

The amount of polyethylene wax (W) can be calculated as: W = (7/100) * Total Adhesive

Practical Example for Pressure-Sensitive Adhesives

For a 1000 g batch of pressure-sensitive adhesive:

• Base Polymer: 550 g
• Tackifier: 350 g
• Polyethylene Wax: 70 g
• Additives: 30 g

These calculations provide a foundational guide for incorporating polyethylene wax into adhesive formulations.
