Products Description
A high-performance polymer known as anhydride modified polyphenylene oxide (PPO) combines the fantastic qualities of polyphenylene oxide (PPO) with the increased functionality offered by anhydride modification. A flexible material that provides great performance in a variety of applications is produced by this special combination.
The polyphenylene oxide treated by an anhydride has exceptional electrical, mechanical, and thermal stability. The material’s reactivity is increased by the anhydride alteration, enabling better adherence to other substrates and additive compatibility. It is the perfect option for applications that demand excellent performance in difficult situations because of this capabilities.
Coace®CS-1 is an anhydride modified polyphenylene oxide. 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.

- Enhancement of Polymer Compatibility: The compatibilizers are designed to make polyamide and PPO polymers, which have a restricted miscibility by nature, more compatible. The creation of a well-dispersed and linked polymer matrix is made possible by their promotion of interfacial adhesion and mix homogeneity.
- Reactive Functional Groups: The compatibilizers include reactive functional groups that help the polyamide and PPO phases interact and form chemical bonds. The polymer blend’s mechanical characteristics, thermal stability, and interfacial strength are all improved by this molecular compatibility.
- Customized Molecular Structure: Reactive modifiers, grafted copolymers, block copolymers, and other molecular structures can be added to the compatibilizers. Because of their adaptability, their performance can be optimized in particular polymer mix systems, allowing compatibility and attributes to be tailored to specific application requirements.
- Process Versatility: Melt blending, extrusion, injection molding, and compounding are just a few of the processing methods that the compatibilizers can be used with. They are simple to add into the formulation of the polymer mix, guaranteeing processing simplicity and compatibility with current manufacturing procedures.
Advantage
Improved Mechanical qualities: Polyphenylene oxide’s mechanical qualities, such as stiffness, strength, and impact resistance, are improved by the anhydride alteration. The enhanced dimensional stability of CS-1 makes it appropriate for applications demanding durability and structural integrity.
Chemical Resistance: The CS-1 has outstanding resistance to a wide range of chemicals, including acids, bases, and solvents. By enabling its usage in situations where exposure to harsh substances is anticipated, this property ensures the durability and dependability of the material.
Electrical Insulation: CS-1 is a useful material for electrical and electronic applications due to its inherent electrical insulating qualities. It is useful for components that require dependable electrical insulation because of its high dielectric strength, low dielectric constant, and superior insulation performance.
Compatibility: A variety of polymers, such as polystyrene (PS), polycarbonate (PC), and polyamide (PA), are quite compatible with CS-1. This compatibility makes it simple to compound and blend with other materials, allowing for the creation of customized composites with improved qualities.
