Main Content

SAG products are random styrene-acrylonitrile-glycidyl methacrylate

terpolymers:

The main chain has excellent

compatibility with ABS, ASA,MPPO

Structure of SAG

The GMA is highly reactive with various

chemical groups such as COOH, OH, NH2 ,

etc. So that SAG has excellent compatibility

with PA, PBT, PET, PC, etc.

Main Content

Objects: engineering plastics such as PC/PBT, PC/PET ,PBT/PET have good

mechanical properties (flexural modulus etc.) but their main defects are poor heat

stability due to over ester exchange

Advantage: accomplish excellent heat stability under high temperature and strong

shear conditions by “repairing” of low molecular weight degraded polymers and

“suppressing the ester exchange”. keep intrinsic viscosity, avoid appearance

yellowing and crazing.

Main Content

Objects: Weak interfacial bonding between glass fiber and ABS , AS, polyester

result in inefficient load transfer and this significantly decreases the mechanical

properties of the glass fiber reinforced composites.

Advantage: The epoxy group of SAG can react with functional groups of fillers

such as glass fiber, talcum powder, leading to the formation of “nuclear- shell”

composite and improving physical and mechanical properties.

Main Content

Objects: act as polymeric chain extender of degraded polymers such as PET、PBT、

PC、PA、TPU and biodegradable materials such as PLA、PBS、PHA、PHB、PCL.

Advantage: to restore the original molecular weight and intrinsic viscosity as well as

melt viscosity, increase the melt strength of degraded polymers, improve processability of

low quality recycled plastics, essentially.
