Product Application
AMSD is Alpha-Methyl Styrene Dimer, with the chemical name 2,4-diphenyl-4-methyl-1-pentene, molecular weight 236.36 and CAS No. 6362-80-7.
As a revolutionary eco-friendly molecular weight regulator, AMSD successfully addresses the malodor and environmental issues associated with traditional mercaptan-based regulators through its unique molecular structure, without compromising product performance. It not only enables precise control over polymer molecular weight and distribution, but also comprehensively enhances product performance and processing efficiency. AMSD has emerged as a key additive for green manufacturing in the polymer materials sector, and is particularly suited for high-end applications with stringent requirements for environmental friendliness, odor reduction and product performance.
Main Applications of AMSD
Polymer Synthesis (Core Application)
Acrylic Resins:
Regulates molecular weight to produce resins with smaller and more uniform molecular weight distribution;
Significantly improves leveling property, reduces viscosity, and enhances transparency and weather resistance.
Styrenic Resins:
Serves as a high-efficiency chain transfer agent in the polymerization of ABS, PS, AS, EPS, HIPS and other styrenic polymers;
Replaces traditional sulfur-containing regulators to improve product environmental performance and processing stability.
Latex Synthesis:
Controls molecular weight distribution in styrene-butadiene latex, nitrile-butadiene latex, styrene-acrylic latex, etc., and improves film-forming properties.
Plastic Processing Additive
Rheological Property Modification: Significantly reduces the melt viscosity of polyolefins (PE, PP), improves processing efficiency and lowers energy consumption.
Filler Masterbatch Production: Increases filler loading, reduces processing energy consumption and enhances product strength.
Can be used as a partial substitute for plasticizers such as DOP, reducing costs and improving environmental performance.
Other Innovative Applications
