PPE/PS (polyphenylene ether/polystyrene)
Description (definition)
PPE/PS is a thermoplastic blend that combines the excellent electrical insulation properties and heat resistance of polyphenylene ether (PPE) with the easy processability and rigidity of polystyrene (PS). This blend is often used for technical applications where a combination of heat resistance, electrical insulation and dimensional stability is required.
Example
A typical example of PPE/PS is its use in housings for electrical appliances such as transformers or switch boxes. The electrical insulation properties and mechanical stability ensure safe and long-lasting use.
What advantages does PPE/PS offer in electrical applications?
PPE/PS has excellent electrical insulating properties combined with high heat resistance. This makes it ideal for connectors, switch housings and other components in the electronics industry.
Why is PPE/PS often used in the automotive industry?
In the automotive industry, PPE/PS is used for fan housings, air ducts and other components that have to withstand high thermal and mechanical loads. Its dimensional stability and chemical resistance make it particularly suitable for technical components.
Can PPE/PS be recycled?
Yes, PPE/PS is recyclable. However, the recycling process is more demanding than for unmixed plastics. Recycled PPE/PS is often reused in less critical applications, such as housings or technical components.
