Overview
ALITA L-7310 Polystyrene-based Low Profile (LP) Additive (High Coloring Type)
Category：Low Shrink AdditivesCode：ALITA L-7310 Low Profile (LP) Additive
Applications
ALITA L-7310 is a high-coloring type low shrinkage additive based on Polystyrene, with styrene as the diluent.
- Shrinkage Control & Appearance: Provides exceptional shrinkage control, capable of producing extremely flat and glossy product surfaces.
- Excellent Coloring Property: Specifically designed for SMC/BMC products requiring vibrant or uniform colors, featuring outstanding color stability.
- Chemical Characteristics: Free of acid groups, making it an ideal carrier for magnesium oxide (MgO) thickeners without interfering with the thickening reaction.
- Cost Advantage: Features low viscosity and high solid content, allowing for a higher proportion of fillers in the formulation, effectively reducing production costs.
