Key Distinctions
- Flammwidrigkeit:
- Flame-retardant PP sheets are specially designed with additives, such as halogenated or phosphorus-based compounds, to resist ignition and slow the spread of flames. This enhances their safety in fire-prone environments.
- Ordinary PP sheets do not contain these additives, making them more flammable and less suitable where fire resistance is needed.
- Cost:
- Flame-retardant PP sheets are typically more expensive due to the additional materials and manufacturing processes required to make them fire-resistant.
- Ordinary PP sheets are more budget-friendly, as they don’t involve these extra steps.
- Physikalische Eigenschaften:
- Flame-retardant PP sheets may exhibit minor differences in color, texture, or mechanical properties depending on the flame-retardant additives used, though they retain PP’s core traits like durability and versatility.
- Ordinary PP sheets maintain the standard characteristics of polypropylene, including being lightweight, flexible, and chemically resistant.
- Anwendungen:
- Flame-retardant PP sheets are commonly used in settings where fire safety is critical, such as electrical enclosures, automotive parts, and building materials. They often comply with flammability standards like UL 94.
- Ordinary PP sheets are suited for general-purpose uses like packaging, signage, and consumer products where fire resistance isn’t a priority.
Zusammenfassung
The primary difference lies in their fire-resistant capabilities, with flame-retardant PP sheets offering enhanced safety at a higher cost, while ordinary PP sheets are a more economical choice for non-fire-sensitive applications. Your choice depends on the project’s safety needs and budget.
