Product Description

Product Description

MBS (MethylMethacrylate-Butadiene-Styrene)

1.Impact modifier MBS
Impact resistant MBS resin is mainly used in the PVC processing and forming process, without damaging the inherent characteristics of PVC
Under the premise, improve its impact strength. Due to its similar solubility parameters to PVC, the two are thermodynamically compatible
Good performance, manifested by impact strength, temperature resistance PVC, and high impact color resistance when applied at room temperature or low temperature.
2.Transparent modifier MBS
Transparent MBS resin is mainly used in the processing and forming of transparent PVC products, especially in non-destructive transparent PVC production
Under the premise of inherent characteristics of the product, improve its impact resistance strength. Its refractive index is similar to PVC, using
MBS PVC is an impact resistant PVC material, and the impact modifier does not affect the optimal PVC material for manufacturing transparent products. Transparency is an improvement
3.Compared with other companies, our MBS has higher impact resistance and better compatibility Grinding properties.

Improved Impact Resistance

Clarity and Transparency

MBS significantly enhances the ability of PVC to withstand impact and stress, making it more durable.

Enhanced Toughness

MBS increase the material's resistance to deformation and tearing, improving overall durability

MBS can be formulated to maintain the clarity of transparent PVC products, which is crucial for applications like packaging and medical devices. 

Enhanced Processing

MBS improves the flow properties of PVC during manufacturing, allowing for faster production speeds and more complex shapes.

Application

Transparent PVC Packaging Films

Purpose:
To enhance impact resistance in low-temperature environments without sacrificing extrusion processing performance.

Performance Highlights:

Impact Strength (Charpy / Notched Izod): Improved by 50–200%, depending on formulation
Melt Flow Characteristics: Enhanced, resulting in better extrusion rates and improved surface finish
Result:
Profiles and frames modified with MBS exhibit superior mechanical toughness and remain ductile in cold-weather conditions. At the same time, improved melt flow ensures efficient processing and smoother surfaces. This makes MBS an ideal solution for outdoor construction applications such as window frames, siding, and other structural profiles exposed to winter environments.

Rigid PVC Sheets and Thermoformed Products

Purpose:
To enhance drop impact resistance and thermoformability of rigid sheet materials.

Performance Highlights:

Drop Dart Impact Resistance: Improved by 2–3 times, depending on formulation and processing conditions
Heat Stability: Slightly increased due to improved fusion behavior and dispersion of MBS
Result:
The incorporation of MBS enables rigid sheets-such as those used in blister packaging, loyalty or credit cards, and clamshell containers-to better withstand mechanical stress during forming and end-use. Products retain structural integrity and surface quality after thermoforming, while also exhibiting improved resistance to cracking or breakage under impact.

Transparent PVC Bottles & Containers

Purpose:
To prevent environmental stress cracking and enhance handling strength, especially under cold-chain conditions.

Performance Improvements:

Tensile Elongation at Break: Increased by 50-80%, providing greater flexibility and resistance to mechanical stress
Low-Temperature Impact Retention: Improved by up to 5x at -10°C, maintaining toughness during cold storage and transportation
Result:
Bottles modified with MBS remain structurally sound and free from cracking throughout filling, sealing, and logistics processes—even under low-temperature conditions. This ensures better product protection and extended service life in demanding packaging environments.

PVC Profiles and Window Frames (Non-transparent grades)

Purpose:
To enhance impact resistance in low-temperature environments without sacrificing extrusion processing performance.

Performance Highlights:

Impact Strength (Charpy / Notched Izod): Improved by 50–200%, depending on formulation
Melt Flow Characteristics: Enhanced, resulting in better extrusion rates and improved surface finish
Result:
Profiles and frames modified with MBS exhibit superior mechanical toughness and remain ductile in cold-weather conditions. At the same time, improved melt flow ensures efficient processing and smoother surfaces. This makes MBS an ideal solution for outdoor construction applications such as window frames, siding, and other structural profiles exposed to winter environments.

FAQ

Q1: What is MBS resin?
MBS is a terpolymer of methylmethacrylate, butadiene, and styrene, used to improve the impact strength of PVC.
Q2: What are the key advantages of MBS?
High transparency, excellent impact resistance, and good processability.
Q3:What PVC products is MBS suitable for?
Transparent sheets, packaging films, fittings, and indoor non-weatherable PVC products.
Q4: Is MBS suitable for outdoor applications?
Not recommended. MBS is not UV-resistant and is mainly for indoor use.
Q5:Does MBS affect PVC transparency?
No. MBS actually enhances transparency and gloss.
Q6:What is the typical dosage?
Typically 5–10 phr, depending on performance requirements.
