Key Features: Unmodified or disproportionated rosins derived from tall oil. Used as raw materials for emulsifiers or directly in inks, coatings, paper sizing, and adhesives.

Tall Oil Rosins (Unmodified)

Disproportionated Rosins

| Product | Acid Number (mg KOH/g) | Softening Point (°C) | Key Characteristics |
| :--- | :--- | :--- | :--- | :--- |
| DR 731D | 150 – 170 (154) | Drop point ≥85°C | Very good color stability, dehydroabietic acid ≥45% |
| DR22 | ≥155 (165) | ~64°C (Mettler) | Dehydroabietic acid ~55%, low abietic acid |

1. Industry Suitability & Application Table

2. Recommended Usage Ratios (Tackifier to Base Polymer)

Usage ratios vary significantly based on the specific polymer and desired properties (softness vs. adhesion vs. heat resistance). The table below provides general starting points for hot-melt formulations.

Production Note: In hot-melt formulations, a plasticizer (e.g., mineral oil, 5-20 phr) is often added to reduce viscosity. For PSA applications, the tackifier-to-polymer ratio is generally higher (often >100 phr) to achieve aggressive tack.

3. Production Processes & Manufacturing

Understanding how these products are made helps in selecting the right grade for stability and performance.

A. Crude Tall Oil (CTO) Fractionation (Rosin & Fatty Acid Production)

• Feedstock: Crude Tall Oil (pine wood pulping by-product).

• Process: Vacuum distillation separates the CTO into heads (turpentine), rosin (abietic acid), and tails (fatty acids).

• Outputs: SYLVAROS (Tall Oil Rosin), SYLFAT (Fatty Acids).

B. Disproportionation (For Emulsifiers & Stable Rosins)

• Process: Tall oil rosin is heated with a catalyst (e.g., iodine or noble metals) to convert less stable Abietic Acid into more stable Dehydroabietic Acid .

• Outputs: SYLVAROS DRS series (DRS 40, 42, 214, 215, 731) and SYLVAROS DR (DR22, DR 731D).

C. Esterification (For Tackifiers)

• Process: Rosin or Disproportionated Rosin is reacted with alcohols (Glycerol or Pentaerythritol) at high temperatures (200-280°C) to form esters.

• Catalyst: Zinc acetate or similar to speed up the reaction.

• Outputs: SYLVATAC RE series (RE 85, RE 103S) and SYLVATAC 2098.

D. Polymerization (For Terpene & AMS Resins)

• Feedstock: Alpha/Beta Pinene (SYLVAPINE) or Alpha-Methyl Styrene (petroleum-based).

• Process: Cationic polymerization using Friedel-Crafts catalysts (e.g., AlCl₃, BF₃) in a reactor.

• Outputs: SYLVARES TR series (Polyterpenes) and SA series (AMS Resins).

E. Saponification (For Soaps)

• Process: Rosin is neutralized with an alkali (KOH for Potassium soaps, NaOH for Sodium soaps) in water.
