1.Introduction
Pressure-Sensitive Adhesives (PSA) hot melt formulations are versatile bonding solutions that provide instant tack and permanent adhesion upon light pressure application. Unlike traditional adhesives, PSAs don't require curing or activation - they adhere immediately while remaining removable/repositionable in some applications. These adhesives are widely used in labeling, tapes, medical patches, and automotive trim applications.
This guide covers:
✅ Key components of PSA hot melt formulations
✅ Manufacturing process step-by-step
✅ Special properties & applications
2.Production Process of PSA Hot Melt Adhesives
Step 1: Raw Material Preparation
-
Pre-drying of hygroscopic components (resins, fillers)
-
Accurate weighing of all formulation ingredients
Step 2: Melt Compounding
-
Primary Melting:
-
Base polymers melted first in heated sigma blade mixer (120-180°C)
-
Maintained under nitrogen blanket to prevent oxidation
-
-
Resin Incorporation:
-
Tackifiers gradually added under high shear mixing
-
Temperature controlled to avoid thermal degradation
-
-
Additive Blending:
-
Plasticizers, stabilizers, and other additives incorporated
-
Homogenized for 1-3 hours until uniform viscosity achieved
-
Step 3: Filtration & Degassing
-
Molten adhesive passed through mesh filters (50-200µm)
-
Vacuum degassing to remove entrapped air bubbles
Step 4: Forming & Packaging
-
Die-cutting into blocks, pellets, or slugs
-
Coating directly onto release liners for tape applications
-
Special packaging in moisture-barrier materials
Step 5: Quality Control Testing
-
Tack: Rolling ball/loop tack tests
-
Peel Adhesion: 180°/90° peel tests
-
Shear Resistance: Holding power measurements
-
Rheology: Melt viscosity & softening point
3.Raw Materials for PSA Hot Melt Adhesives
1. Base Polymers (30-60%)
-
Styrenic Block Copolymers (SBCs):
-
SIS (Styrene-Isoprene-Styrene) - excellent tack & flexibility
-
SBS (Styrene-Butadiene-Styrene) - better strength & heat resistance
-
-
Amorphous Polyalphaolefins (APAO): Good UV/aging resistance
2. Tackifying Resins (30-50%)
-
Hydrocarbon resins (C5 aliphatic, C9 aromatic, or mixed)
-
Rosin esters (gum, tall oil, or wood rosin derivatives)
-
Terpene resins (natural or synthetic)
3. Plasticizers (0-20%)
-
Mineral oils (naphthenic/paraffinic)
-
Polybutenes
-
Liquid tackifiers
4. Stabilizers & Antioxidants (0.5-3%)
-
Phenolic antioxidants (BHT, Irganox)
-
Phosphite stabilizers
-
UV stabilizers for outdoor applications
5. Fillers & Additives (0-15%)
-
Waxes (adjust viscosity/set time)
-
Pigments (colorants)
-
Rheology modifiers
