MBS’s Introduction

MBS is a most major impact modifier with light yellow or orange crystal / granular. MBS is a copolymer of three monomers, methyl methacrylate, butadiene and styrene. No poison with a little odor of ammonia. The density is 1.34-1.40. Slightly soluble in benzene, ethyl alcohol and carbon tetrachloride, insoluble in water,ethanol, butanone, chloroform swelling. Solubility parameter is 9.4-9.5, close to the solubility parameter of PVC, has good compatibility with PVC.

Feature of MBS

Good impact properties, good transparency, light transmittance up to 90%

Less impact to the tensile strength and elongation at break

Not only toughening, but also maintaining the transparency of PVC maxium.

Good chemical stability and thermoplasticity.

Promoting plasticization and improving the surface finish of products

In the same amount of circumstances, can greatly enhance the toughness of the products

Application of MBS

1. MBS used in PVC films and sheets

2. MBS used in PVC bottle pellets, twisted conjunctiva

3. MBS used in PVC high-impact opaque products

4. MBS used in manufacturing of tires, shoes and belts

5. MBS used in food and drug packaging

6. MBS used in other rubber additive


MBS is packing in 20kg bag

MBS should stored in dry and cooling place with good ventilation, avoiding exposure of packaged product to direct sunlight.
