What is the temperature range of PPH?

Polypropylene homopolymer (PPH) is a type of thermoplastic polymer that is widely used in various industries due to its excellent properties such as high chemical resistance, low density, and excellent thermal stability. Additionally, PPH is also known for its ability to withstand high temperatures.

The temperature range of PPH varies depending on the specific application and the conditions in which it is used. In general, PPH can withstand a temperature range of -20°C to 110°C without undergoing significant degradation or changes in its physical properties. However, some grades of PPH can withstand even higher temperatures up to 120°C.

PPH has a high melting point of around 160°C, which means that it does not start to soften until it reaches this temperature. This property makes PPH an ideal material for high-temperature applications such as hot water pipes and automotive parts. In addition, PPH can also maintain its mechanical properties in the presence of hot water or steam, making it a suitable material for use in the food and beverage industry.

One of the significant advantages of PPH is its excellent resistance to most chemicals, including acids, alkalis, and organic solvents, making it an ideal material for chemical storage tanks, laboratory equipment, and other chemical processing applications. At high temperatures, PPH still maintains its chemical resistance, making it a reliable material for use in aggressive chemical environments.

Apart from its high-temperature and chemical resistance, PPH is also known for its good electrical properties, which make it an ideal material for use in electrical components and insulators. Unlike other polymers, PPH does not absorb moisture, which can affect its electrical properties, even when exposed to high humidity conditions.

In terms of its mechanical properties, PPH is a relatively stiff and hard material with a high tensile strength and impact resistance. PPH can withstand repeated bending and flexing without cracking or breaking, making it an ideal material for use in plastic hinges and other flexible components.

In summary

The temperature range of PPH is relatively broad and varies depending on the specific application and use conditions. However, in general, PPH can withstand a temperature range of -20°C to 110°C without significant degradation of its physical properties. The excellent properties of PPH, including its high-temperature and chemical resistance, good electrical properties, and mechanical strength, make it an ideal material for use in a wide range of applications across various industries, from chemical processing to electrical engineering and automotive.
