The testing standards for food grade industrial rubber sheets are crucial for ensuring food safety and consumer health.Food grade rubber sheets are widely used in daily items such as baby pacifiers,rubber gaskets for food containers,washers,bottle stoppers,and pressure cooker seals.Therefore,their quality and safety must undergo rigorous testing.
I.Testing Standards for Food Grade Rubber
1.National Standards:China has a strict set of national standards for food grade rubber products,which stipulate the hygiene indicators,environmental protection,and toxicity testing methods for various food contact materials.These testing items include the content of volatile substances,heavy metal content,and the determination of specific migration amounts.
2.FDA Standards:The U.S.Food and Drug Administration(FDA)also has a detailed set of standards for evaluating the safety of food contact materials.The FDA requires food grade rubber to pass a series of toxicological tests,such as leaching tests and sensory tests,to ensure that the material does not contaminate food.Our food grade rubber sheets have passed the standard certification of US FDA 21 CFR 177.2600,＞send emails to sales@jingdongrubber.com,get a quote now
3.EU Environmental Requirements:The EU also has very strict requirements for food contact materials,especially regarding the restriction of toxic and harmful substances.For example,the EU REACH regulation strictly limits the use of certain chemicals and requires all food contact materials sold in the EU market to comply with its safety standards.
II.Common Testing Items
1.Apparent Density:This is an important parameter for measuring the compactness of rubber materials and directly relates to their physical properties.
2.Tensile Strength:It refers to the material’s ability to resist fracture during stretching and is a key indicator for evaluating the durability of rubber materials.
3.Compressive Strength:It measures the material’s ability to resist deformation under pressure,which is particularly important for rubber products that need to withstand pressure,such as seals.
4.Water Absorption Rate:It indicates the material’s ability to absorb water.A low water absorption rate helps maintain the material’s dimensional stability and mechanical properties.
5.Thermal Conductivity:It represents the material’s ability to conduct heat.For rubber materials that require good insulation performance,this is an important parameter.
6.Resilience:It describes the material’s ability to return to its original shape after being stressed.This is very important for rubber products that need to be used repeatedly,such as keys and washers.
7.Combustion Performance:It includes the material’s flammability,flame retardancy,and other characteristics,which directly relate to usage safety.
III.Specific Application Cases
1.Baby Pacifiers:As baby products,they require extremely high hygiene standards.Testing items include heavy metal content,nitrosamine content,and sensory tests.
2.Rubber Gaskets for Food Containers:They are used to seal food containers to prevent leakage and contamination.Testing items mainly include total migration,specific migration,and sensory tests.
3.Pressure Cooker Seals:They need to be heat-resistant and pressure-resistant.During testing,attention is paid to their heat aging performance and compression set.
4.Water Dispenser Hoses:They are used to transport drinking water.Testing focuses on volatile organic compound content,microbial contamination,and heavy metal leaching.
The testing standards and items for food grade industrial rubber sheets are very comprehensive,covering various aspects from basic physical properties to advanced chemical safety.These strict standards not only ensure product quality but also safeguard consumer health and safety.
