MBS (methyl methacrylate butadiene styrene)
Description (definition)
MBS (methyl methacrylate-butadiene-styrene) is a copolymer consisting of the monomers methyl methacrylate (MMA), butadiene and styrene. It combines the high transparency and surface hardness of methyl methacrylate with the impact strength of butadiene and the heat resistance of styrene. Due to its optical clarity and mechanical properties, MBS is mainly used as an impact modifier for plastics such as PVC.
Example
A typical example of the use of MBS is the production of impact-resistant PVC for window profiles. The addition of MBS makes the PVC more resistant to mechanical stress without impairing its transparency.
What advantages does MBS offer as an impact modifier?
MBS significantly improves the impact strength of plastics such as PVC. It increases resistance to cracking and breakage, especially at low temperatures, while retaining the optical clarity and transparency of the material.
Where is MBS used in the industry?
MBS is widely used in the construction industry, e.g. in PVC window profiles and pipes. It is also used in packaging materials and transparent films where a combination of strength and clarity is required.
Is MBS recyclable?
Yes, plastics containing MBS are recyclable, especially in closed loops such as in the construction or packaging industry. The impact strength is largely retained even after the recycling process, which makes MBS a sustainable choice.
