LB-136

Type: MBS Impact Modifier

Development / Applications

MBS LB-136 is a terpolymer of methyl methacrylate, butadiene, and styrene, primarily used in the rigid PVC process. Its main characteristics are high impact resistance, good transparency, good processability, shorter gelation time, and less crease-whitening. It can be used in opaque or transparent applications.Its fast fusion contributes to higher output, its greater impact efficiency allows for reduced MBS dosage and cost savings in formulation, and it improves the impact properties of blow-molded PVC products, injection-molded parts, calendered sheet and tubing, PVC films, laminated materials, granular materials, pipe for indoor use, and pipe fittings.
