CS-1anhydride modified polyphenylene oxide.

Coace®CS-1 is a type of anhydride modified polyphenylene oxide (PPO). PPO is a high-performance engineering plastic that has excellent thermal and mechanical properties, including high heat resistance, good dimensional stability, and low moisture absorption.

The anhydride modification of PPO involves the introduction of reactive carboxylic acid groups onto the polymer chain, which can react with other materials, such as polyamides, to form strong intermolecular bonds. This modification improves the compatibility of PPO with other materials, particularly with polar materials like polyamides, and enhances the adhesion between different layers in a composite material.

 It is known for its high heat resistance, excellent dimensional stability, and good processability. Coace®CS-1 is often used as a matrix material in composite materials for automotive, electrical, and electronic applications, where its excellent thermal and mechanical properties are required. It is also used in various other applications such as connectors, housings, and structural parts in a range of industries.
