PP is slightly more heat resistant than HDPE and is often used in products that require a higher level of durability, such as storage containers and bins. Both HDPE and PP are considered safe for food contact by the FDA, making them suitable for use in kitchen products.
The heat resistance of Rubbermaid products can vary depending on the specific type of plastic used and the product's design. For example, some products may have a heat resistance rating of up to 250°F (120°C), while others may be able to withstand temperatures of up to 400°F (200°C). It's always important to check the product's label or packaging for specific heat resistance information before using it in high-temperature applications.
To ensure the longevity of Rubbermaid products, it's recommended to avoid exposing them to extreme temperatures whenever possible. This includes not leaving them in direct sunlight for extended periods or using them in ovens or on stovetops. By following these guidelines, you can help maintain the integrity of the products and ensure they continue to perform as expected.
In summary, while Rubbermaid products are made from heat-resistant plastics like HDPE and PP, they are not completely heat proof. It's important to understand the specific heat resistance properties of each product and use them accordingly to ensure their longevity and safety.
