One of the many products we offer here at SACO Distribution is our chain extenders, which are made by one of our business partners, Fine-Blend.
The recycled polyester or polyamide materials often degrade seriously by many times shearing or thermal history, which leads to broad molecular weight distribution. Eco-BatchTM has a high concentration of epoxy groups, which can react with the terminal groups of the recycled polyester or polyamide to prevent further degradation, increasing the melt viscosity and improving processing stability.
Styrene-acrylonitrile-glycidyl methacrylate terpolymer SAG-008 is highly reactive with chemical groups, such as COOH, NH2, OH, et cetera.
As a result, SAG-008 is an effective chain extender for polymers like polyesters, polycarbonates, polyamides, and polyurethanes as well as alloys of these polymers.
With a close reactive system with PC end-groups, Fine-Blend SAG-008 improves the melt viscosity, processability, chemical stability, mechanical properties, and usually reduces gloss levels.
The Fine-Blend SG-20 chain extender consists of a high percentage of GMA groups; it is very reactive and suitable for polyesters (PBT, PET) and polyester-based biopolymers like PLA and PBAT.
The Fine-Blend ECO-1120 chain extender is designed specifically for transparent polycarbonate.
