• PP: Max Service Temperature - 150°C; Tensile Strength - 28-45MPa; Friction Coefficient (Aluminum) - 0.1-0.25; Friction Coefficient (Steel) - 0

Chemical Properties Comparison

We're going to compare the chemical properties of pom, delrin, acetal, and polypropylene. Specifically, we'll look at their resistance to acids, bases, heat, cold, and sun damage.

Let's take a closer look at each material and how it compares to the others in these areas.

Resistance to Acids and Bases

Discover how each material stands up to acids and bases - it might surprise you! When exposed to strong acids and bases, both pom/delrin/acetal and polypropylene experience significant deterioration.

The difference between the two lies in their respective resistance levels. POM/Delrin/Acetal is much more resistant than polypropylene, as they're all hydrophobic materials that resist water absorption. This makes them less likely to suffer damage from acidic or basic solutions.

Polypropylene, on the other hand, is a semi-crystalline thermoplastic that's hydrophilic; this means it absorbs water quickly and breaks down when exposed to high concentrations of acid or base. Therefore, pom/delrin/acetal are better suited for applications where they'll be exposed to chemicals such as sulfuric acid or sodium hydroxide than polypropylene.

Resistance to Heat and Cold

We're always looking for materials that can withstand the tests of time. When it comes to heat and cold resistance, POM/Delrin/Acetal and polypropylene offer dramatically different results. POM/Delrin/Acetal's ability to withstand extreme temperatures symbolizes its superior durability.

Here are some key differences between these two materials:

• POM/Delrin/Acetal is able to survive in temperatures ranging from -40°F to 250°F (-40°C to 120°C), making it ideal for outdoor applications and high-temperature environments.
• On the other hand, polypropylene has a much lower melting point (320°F or 160°C) and is more suitable for indoor applications or low-temperature settings.
• In terms of thermal stability, POM/Delrin/Acetal is more resistant to deformation while exposed to heat compared with polypropylene which can become brittle at certain temperatures.
• Lastly, POM/Delrin/Acetal offers much better insulation than polypropylene due to its higher insulating capacity at both low and high temperatures.

Whether you're looking for an industrial material that stands up against extreme heat or cold, both POM/Delrin/Acetal and polypropylene offer excellent solutions depending on your needs. However, if you're concerned about long-term performance in harsh conditions then the superior resistance of POM/Delrin/Acetal makes it the obvious choice!

Resistance to Sun Damage

We all know that exposure to the sun can cause damage, and this is true for materials too. Both POM/Delrin/Acetal and polypropylene offer varying levels of resistance to sun damage, so it's important to consider the environment in which the material will be used.

When it comes to POM/Delrin/Acetal, UV radiation from sunlight can cause discoloration and brittleness over time. However, these materials are generally more resilient than polypropylene when exposed to direct sunlight; they resist cracking or fading if properly maintained.

On the other hand, polypropylene has a high resistance to UV radiation but tends to become brittle when exposed for long periods of time. This means that when using PP outdoors it should be given extra protection against direct sunlight in order for it to maintain its strength and integrity over time.

Ultimately, both materials have their strengths and weaknesses in terms of sun damage - depending on your application you'll need to decide which one is best suited for your needs!
