Product Description

1. Product Overview

MBS impact modifier is a core-shell polymer of methyl methacrylate butadiene styrene ternary copolymer, specifically designed to enhance the impact resistance of transparent/semi transparent PVC products. Its unique "hard shell soft core" microstructure makes it the only PVC modifier that can simultaneously meet high transparency and high impact resistance requirements.

2. Key characteristic parameters

-Core shell structure:

-Core layer: Butadiene rubber phase (providing toughness)

-Shell: MMA/ST copolymer (ensuring compatibility)

-Refractive index: 1.52-1.54 (perfectly matched with PVC 1.52-1.55)

-Particle size distribution: 0.1-0.3 m (optimal light scattering control)

-Glass transition temperature:

-Core layer: -80 (low temperature impact resistance)

-Shell: 105 (thermal stability)

3. Core functional advantages

Excellent optical performance

-Transmittance>90% (550nm wavelength)

-Haze<5% (2mm thick sample)

-Can prepare medical grade transparent products

Efficient toughening effect

-Increase gap impact strength by 10-20 times

-Maintain good toughness at -10

Processing adaptability

-Wide melting temperature range (160-200 )

-Good compatibility with PVC melt

4. Typical application areas

Transparent products (main applications)

-Medical packaging: infusion bags/bottles (dosage 8-12 phr)

-Food packaging: transparent container/cling film (5-10 phr)

-Daily necessities: cosmetic bottles/stationery (6-10phr)

Special requirements products

-Electrical panel (flame retardant model required)

-Automotive interior parts (low temperature resistant models)

-Instrument window (ultra-high transparency model)

MBS impact modifier achieves ABS grade impact strength by precisely controlling the core-shell ratio and particle size distribution, while maintaining the original transparency of PVC. It is currently an irreplaceable key modified material for transparent PVC products. With the increasing demand for medical packaging and high-end food packaging, this product is developing towards a cleaner and more specialized direction.
