🧪 Material Composition & Performance – White Food Grade Nitrile Rubber Sheet (NBR)

The White Food Grade Rubber Sheet is manufactured from high-quality synthetic nitrile butadiene rubber (NBR)—a premium compound developed specifically for hygienic, food-safe, and oil-resistant applications.

 

🏗️ Material: White NBR (Nitrile Butadiene Rubber)

Nitrile is a synthetic rubber known for its:

• Excellent resistance to edible oils, animal fats, and greases
• Superior tensile strength and wear resistance
• Low permeability to gases and liquids
• Good elasticity and compression set resistance
• Resistance to cleaning chemicals (alkalis, acids, detergents)

 

RUBASIA’s white nitrile formulation is custom-compounded to meet stringent FDA 21 CFR 177.2600 requirements, ensuring safety for direct and repeated contact with dry, aqueous, and fatty foodstuffs.

🧼 Why Choose White NBR Rubber for Food Environments?

White nitrile rubber is specifically chosen over natural rubber or other synthetic rubbers for applications where:

• Oil and grease contamination is frequent (meat, seafood, bakery lines)
• Aesthetic hygiene is important (white shows contamination easily)
• Compliance with international food safety standards is critical
• Cleaning cycles involve frequent washdowns or chemical disinfection

Unlike general-purpose rubber sheets, our white NBR rubber is:

• Non-allergenic (safe for sensitive environments)
• Non-staining and non-discolouring
• Resistant to fungal and microbial growth
• Stable under repeated compression and thermal cycles
