What materials are generally used for the sealing gaskets used in Plastic Logistics Boxes lids?

The sealing gaskets used in plastic logistics boxes lids are typically made from rubber or silicone materials due to their excellent sealing properties and durability. These materials are wellsuited for creating a reliable and watertight seal to protect the contents of the logistics boxes. Here's an overview of the commonly used materials:

1. Rubber Gaskets:

EPDM (Ethylene Propylene Diene Monomer): EPDM rubber gaskets are known for their excellent weather resistance, UV resistance, and resistance to ozone and extreme temperatures. They provide a reliable seal and are often used in outdoor and automotive applications.

Nitrile Rubber (NBR): Nitrile rubber gaskets offer good resistance to oils, fuels, and chemicals. They provide a secure seal and are commonly used in logistics boxes for transporting items that may come into contact with these substances.

Neoprene: Neoprene rubber gaskets are known for their resistance to weathering, abrasion, and moderate chemicals. They provide a durable and flexible sealing solution.

Natural Rubber: Natural rubber gaskets are costeffective and offer good resilience and flexibility. They are suitable for a wide range of sealing applications.

2. Silicone Gaskets:

Silicone Rubber: Silicone rubber gaskets are highly versatile and can withstand a wide range of temperatures, from extreme cold to high heat. They are also known for their excellent resistance to UV radiation, ozone, and aging. Silicone gaskets provide a reliable and longlasting seal.

3. Foam Gaskets:

Polyethylene (PE) Foam: PE foam gaskets are lightweight, flexible, and offer good cushioning properties. They are often used for cushioning and sealing in logistics boxes, especially when the seal does not require extreme water or chemical resistance.

It's important to select the gasket material based on the specific requirements of the logistics box and the intended use. Factors to consider when choosing a gasket material include the need for water resistance, chemical resistance, temperature range, and exposure to UV or outdoor conditions. Additionally, the gasket material should be compatible with the lid and box materials to ensure a secure and longlasting seal.
