Product Overview
Styrene Maleimide Copolymer (SMA-I) is a high-performance thermoplastic resin derived from the imidization of styrene-maleic anhydride (SMA) copolymer. CAS No. 9011-13-6 is the CAS number of the SMA raw material and is used as a reference for this modified copolymer.This modification introduces maleimide units into the polymer chain, resulting in enhanced heat resistance, improved mechanical strength, and excellent compatibility with various polymer systems.
Manufactured by Alfa Chemical, a leading China-based supplier, SMA-I is available in flexible packaging options from 1kg research samples to 100kg bulk industrial quantities. The product is widely used as a polymer modifier, nano-dispersant, and heat-resistant resin in demanding applications.
China manufacturer direct. ≥99% purity. Heat resistant. COA and SDS available with every shipment.
For industrial use only. Not for food contact, pharmaceutical, or cosmetic applications without specific regulatory compliance testing.

Frequently Asked Questions
|
Q: What is the CAS number for SMA-I?
SMA-I is a modified copolymer and does not have a single, unique CAS number. 9011-13-6 is the CAS number of the parent SMA (styrene-maleic anhydride) copolymer and is used as a reference. Batch-specific details are provided on the COA.
|
Q: What is the difference between SMA and SMA-I?
SMA-I is an imidized derivative of SMA (styrene-maleic anhydride copolymer), offering enhanced heat resistance and mechanical strength compared to standard SMA.
|
|
Q: What is SMA-I used for?
SMA-I is used as a polymer modifier, nano-dispersant, and heat-resistant resin in coatings, adhesives, composites, and nanotechnology applications.
|
Q: What is the recommended storage condition?
Store at 2-8°C in a cool, dry place, protected from light. The product should be stored in sealed containers to prevent moisture absorption.
|
|
Q: What is the minimum order quantity?
MOQ is 1kg for research samples. Larger quantities (10kg to 100kg) available for industrial and bulk orders.
|
Q: Do you provide COA and SDS?
Yes, COA and SDS are provided with every shipment. Batch-specific documents are available upon request.
