MBS Modifiers
Acrylic MBS Modifier (Methacrylate-Butadiene-Styrene)
This impact modifier is primarily intended for transparent PVC films. Its role is to provide:
- the required strength properties of thin films;
- transparency in the finished product;
- excellent compatibility with PVC;
- faster PVC fusion;
- good powder flowability.

Core-Shell Structure
An MBS modifier is a polymer with a core-shell structure.
Role of the BS (Butyl-Styrene) Core
- increasing impact strength;
- providing transparency.
Role of the Transparent MS (Methyl-Styrene) Shell
- ensuring powder flowability for uniform material feeding;
- providing good compatibility with the PVC matrix and a high degree of dispersion;
- improving PVC fusion.
When a PVC product is subjected to an external impact, the elastomers in the core absorb the load, creating a deformation zone in which mechanical energy is converted into heat. MBS modifiers can therefore substantially increase the impact strength of PVC products.
A properly selected MBS modifier provides the required strength properties and high transparency in the finished product.
