1. Product Introduction

SP-2836: Belongs to polycarboxylate dispersants. Used in solid formulations, it significantly improves suspension rate, disintegration speed, high-temperature resistance, and granulation smoothness. It shows good application effects, especially in solid formulations with low melting points. Addition amount: 3-8%.

2. Physical and Chemical Properties

3. Products Features

1. Strong versatility – improves the suspension rate and solubility of formulations, suitable for most water dispersible granule (WDG) products.

2. High temperature resistance – enhances adaptability to drying temperatures.

3. Low viscosity – provides excellent extrusion smoothness during granulation, making it easy to produce.

4. Application Examples

50% Pymetrozine WDG

Formulation challenge: Pymetrozine is an active ingredient containing crystalline hydrate, which causes the WDG formulation to harden during granulation and reduces extrusion efficiency.

Qingyu Solution: Using the polycarboxylate dispersant SP-2836 resolves the viscosity and granulation smoothness issues.

Other applications: 50% Pymetrozine WDG, 70% Chlorantraniliprole WDG, 80% Pyrimethanil WDG, 80% Fipronil WDG, 75% Nicosulfuron WDG, etc.
