MBS LE-126 IMPACT MODIFIER

MBS LE-126 IMPACT MODIFIER

(MBS Impact Modifier LE-126)

Product Category: Impact modifier and impact resistance enhancer for rigid and transparent PVC

Product Description

MBS LE-126 is an impact modifier based on Methyl Methacrylate–Butadiene–Styrene (MBS) copolymer, designed for rigid PVC and transparent PVC applications.
The product significantly improves impact strength, toughness, and mechanical performance, while effectively reducing brittleness and cracking. At the same time, it maintains high transparency and surface gloss of finished products.

MBS LE-126 is especially suitable for PVC products requiring both high impact resistance and excellent optical clarity.

Key Features

• Significantly enhances toughness and impact resistance of PVC

• Maintains high transparency without haze or whitening

• Excellent dispersion and compatibility with PVC and CPVC

• Improves thermal stability and processability during extrusion and injection molding

• Provides smooth, glossy surface finish and long-term color stability

Applications

• Transparent PVC products: bottles, tubes, sheets, caps, films

• Rigid PVC products: uPVC window and door profiles, pipes, frames, injection-molded fittings

• PVC products requiring high impact strength and superior surface gloss

Recommended Dosage

• 3 – 8% by weight of PVC resin
  (Depending on required impact performance and transparency level)
