Does PPO Material Resist High Temperature

September 01, 2024

PPO (polyphenylene ether) sheet is a high-performance engineering plastic sheet, which is widely used in electronics, electrical appliances, automotive and other industries because of its electrical insulation properties, good chemical stability and high heat resistance. The following is a detailed description of the high temperature resistance of PPO sheet and its application characteristics.

High temperature resistance of PPO sheet

PPO plate has good high temperature performance, specifically in the following aspects:

High glass transition temperature (Tg): the glass transition temperature of PPO sheet is usually around 210°C, which means that at temperatures lower than this, the PPO material maintains good mechanical strength and rigidity.

Continuous use temperature range: PPO sheet is able to maintain stable performance over a wide temperature range, with a continuous use temperature range of typically -50°C to +120°C, and temperatures as high as 150°C to 160°C for short periods of time.

Short-term heat resistance: PPO sheet is able to withstand higher temperatures up to 180°C for short periods of time, which makes it perform better in applications that require brief exposure to high temperatures.

Heat aging resistance: PPO sheet has better heat aging resistance and maintains good physical and chemical properties at long term high temperatures.

Application characteristics of PPO board

Electrical insulation properties: PPO board has excellent dielectric constant and dielectric loss factor, which is suitable for making high-frequency circuit boards, insulating parts and so on.

Chemical stability: except for strong acids and alkalis and some organic solvents, PPO board has good resistance to most chemicals.

Flame retardant: PPO board has good flame retardant properties and can meet UL 94 V-0 grade flame retardant standards without the addition of flame retardants.

Processing performance: PPO sheet is easy to process and mold, can be processed by injection molding, extrusion and other ways to facilitate the manufacture of complex shaped parts.

Usage Scenario

Electronic and electrical industry: as printed circuit board (PCB) substrate, connectors, switch housing, etc.

Automotive industry: used to make parts in the engine compartment, such as sensor housings, wiring harness connectors, etc.

Aerospace: used in the internal components of aircraft, radomes and other parts, utilizing its lightweight and high strength characteristics.

Household appliances: such as microwave oven doors, oven internal components, etc., to take advantage of its high-temperature resistance, not easy to deformation characteristics.

Summarize

PPO sheets are widely used in many industries due to their high temperature resistance and wide applicability. When selecting PPO sheets, it is necessary to consider the specific usage environment and requirements to ensure that they are able to meet the temperature and other performance needs for the particular application. Meanwhile, to get results, it is recommended to consult a specialized material supplier or manufacturer for detailed information on the different grades and modifications available for PPO sheets.
