White NBR rubber for foods refers to a specific formulation of Nitrile Butadiene Rubber (NBR) that is suitable for use in food processing and handling applications. This type of NBR rubber is designed to comply with regulations set forth by food safety agencies, such as the Food and Drug Administration (FDA) in the United States, and similar regulatory bodies in other countries.

Here are some key features and considerations of white NBR rubber for foods:

1. Compliance: White NBR rubber for foods is formulated with ingredients that comply with FDA regulations for materials intended for use in food contact applications. This ensures that the rubber is safe and suitable for handling food products without posing any risk of contamination.

2. Food Grade: This type of NBR rubber is often referred to as “food-grade” or “food-safe” rubber due to its compliance with food safety standards. It is suitable for direct or indirect contact with food items and is commonly used in food processing equipment, conveyors, seals, gaskets, and other components where sanitation and hygiene are critical.

3. Oil Resistance: NBR rubber inherently exhibits good resistance to oils, fats, and greases, which makes it suitable for use in food processing environments where exposure to these substances may occur.

4. Temperature Range: White NBR rubber for foods typically has a temperature resistance range similar to standard NBR rubber, which is approximately -40°C to 120°C (-40°F to 248°F), depending on the specific formulation and grade.

5. Durability: This type of rubber maintains the durability and mechanical properties of standard NBR rubber, including flexibility, elasticity, and resistance to abrasion and tearing, ensuring long-term performance in food processing applications.

White NBR rubber for foods is available in various forms, including sheets, gaskets, O-rings, and extrusions, and can be customized to meet specific requirements for size, thickness, and performance characteristics. It provides a reliable solution for maintaining hygiene and food safety standards in the food and beverage industry.
