Compatibilizers in the Plastics Industry

Our selection of compatibilizer products come from our supplier, Fine-Blend.  Fine-Blend has been the front runner in the compatibilizer field for over 20 years and is the only one who owns both an upstream polymerization and a downstream modification platform.

What are Compatibilizers?

• They are additives that make incompatible polymers compatible.
• They have reactive groups on either end of the polymer chain that react with different polymers. 
• Think of them as a "linking material" in which each end knows what it likes to link to and react with. 
• They are especially important in the recycling of "contaminated" materials.

Chemistry of Compatibilizers

• SAG products are random styrene-acrylonitrile- glycidyl methacrylate terpolymers
  • The main chain has excellent compatibility with ABS, ASA, and MIPPO
  • The GMA is highly reactive with various materials, such as PA, PBT, PET, PC, etc. 

How do Compatibilizers Work?

The terpolymer, styrene-acrylonitrile- glycidyl methacrylate (SAG), reacts with a low molecular weight with a polycarbonate compound or polycarbonate blend.

This allows for better performance and eliminates the residual end groups of PC and active groups from the degradation of PC, which provides double protection.
