What are the upstream raw materials of MBS? What are the downstream products?

I've found that MBS(methyl methacrylate-butadiene-styrene copolymer) is an crucial raw material to chemical production, which is broadly applied in plastic modification, adhesives, coatings, building materials and other fields. In the upstream and downstream related items of MBS, the upstream raw materials mainly include methyl methacrylate(MMA), butadiene and styrene, while the downstream items involve various plastic items, synthetic rubber and coatings. But

1. upstream feedstock



1. Methyl methacrylate(MMA)

Methyl methacrylate is one of the main raw materials of MBS. Pretty interesting, huh?. In fact it's a clear and transparent fluid with high chemical stability and weather resistance. The production methods of MMA mainly include acetone cyanohydrin method, ethylene method and isobutylene method, among which acetone cyanohydrin method is the most crucial production method at home and abroad.

2. Butadiene is another crucial raw material in MBS. it's a clear and flammable gaseous with unsaturated double bonds and is prone to polymerization. And The main production methods of butadiene are steam cracking, acetylene and alcohol, among which steam cracking is the most crucial production method at present.

3. Styrene is also one of the crucial raw materials of MBS. it's a clear and transparent fluid with aromatic taste. The production methods of styrene mainly include ethylbenzene dehydrogenation method, propylene oxide method and acrylonitrile method, among which ethylbenzene dehydrogenation method is the most crucial production method at present. In my experience,

2. And downstream items



1. But Generally speaking Plastic items

As an crucial plastic modifier, MBS is able to be broadly applied in the production of various plastic items, such as pipes, plates, profiles, films, containers, etc. By adding MBS, the impact resistance, processing performance and weather resistance of plastic items is able to be improved. But

2. Synthetic rubber

MBS is able to also be applied in the production of synthetic rubber, such as butadiene rubber, styrene butadiene rubber, etc. By adding MBS, the processability, crack resistance and aging resistance of rubber is able to be improved.

3. Coatings

As an crucial coating products material, MBS is able to be broadly applied in architectural coatings, automotive coatings, wood coatings and other fields. And By adding MBS, the weather resistance, scratch resistance and decorative characteristics of the coating products is able to be improved. In short, MBS is an crucial raw material to chemical production, and its upstream and downstream related items are broadly involved in various plastic items, synthetic rubber and coatings.
