Maleic Anhydride Grafted POE, often called POE-g-MAH or MAH-g-POE, is a functionalized polyolefin elastomer used in polymer modification. It is commonly evaluated as a compatibilizer, nylon toughener, impact modifier and adhesion promoter in engineering plastic systems.
What is POE-g-MAH?
POE-g-MAH refers to polyolefin elastomer grafted with maleic anhydride functionality. The POE backbone provides elastomeric toughness, while maleic anhydride groups can improve compatibility with polar polymers, fillers or reinforced systems.
The actual performance depends on the base polymer, grafting level, melt flow rate, formulation and processing conditions.
Common application areas
POE-g-MAH is often considered for PA6 and PA66 toughening, PA/polyolefin blend compatibility, glass fiber reinforced nylon modification, mineral filled polymer systems, recycled plastic modification and selected adhesion promotion applications.
It should be selected according to the target resin system and performance requirements rather than only by product name.
Key parameters to confirm before RFQ
Before requesting a quotation, buyers should confirm the target polymer system, expected dosage, MAH grafting level, melt flow rate, appearance, processing temperature, impact strength target, filler or fiber content, and required documents such as TDS, SDS and COA.
These details help narrow down suitable grades and avoid mismatches between grade properties and processing requirements.
Why documentation matters
Different suppliers may offer different grades under similar names. TDS and SDS documents are useful for checking appearance, recommended processing conditions, storage, safety handling and grade-specific technical data.
COA availability may depend on batch and supplier.
How Velqora Chem can support sourcing
Velqora Chem can help review CAS or product names, target specifications, application requirements and documentation availability.
For POE-g-MAH and related compatibilizers, sourcing should focus on grade matching, application fit and document review instead of price comparison alone.
FAQ
Is POE-g-MAH the same as a finished adhesive?
No. POE-g-MAH is typically used as a functionalized polymer additive, compatibilizer, adhesion promoter or tie-layer modifier. It should not be described as a universal finished adhesive product.
Can POE-g-MAH be used for PA6 and PA66 toughening?
It is commonly evaluated for PA6 and PA66 modification, but the suitable grade depends on the resin system, processing conditions, dosage and performance requirements.
What documents should buyers request?
Buyers usually request TDS, SDS and, when available, COA. Document availability may vary by supplier, grade and batch.
Can one POE-g-MAH grade fit all polymer systems?
No. Selection should be based on base polymer, grafting level, melt flow rate, target resin system and application requirements.
