How to distinguish the authenticity of food-grade silica gel? 4 core identification methods

Avoid purchasing traps! A complete guide to identifying genuine and fake food-grade silicone

Food-grade silicone products, due to their non-toxic, safe, and high-temperature resistant properties, have become essential for kitchen baking and baby products. However, the market is flooded with inferior counterfeits, making it easy to fall victim to them if you’re not careful. By mastering the following 4 core methods, you can distinguish the genuine from the fake and choose reliable products.

First tip: Check certification marks. Food-grade silicone products must have certifications such as FDA (USA), LFGB (Germany), or China’s GB 4806 standard. The packaging should clearly display the test number and applicable scenarios; products without certification or with vague markings are most likely inferior counterfeits.

Second tip: Observe the appearance and feel the texture. High-quality silicone has an even color, appearing translucent or milky white, with a smooth surface free of impurities. When touched, it is soft and elastic, quickly rebounding after stretching without whitening or cracking. Counterfeits often have cloudy colors, a stiff texture, and are prone to deformation or even breaking when stretched.

Third tip: Smell to distinguish quality. At room temperature, there should be no peculiar smell. Even after boiling in water, it should only have a slight inherent material odor that dissipates quickly after cooling. Counterfeits emit a pungent plastic smell, which becomes stronger at high temperatures and may even release harmful substances.

Fourth tip: Conduct simple tests. Put the product in boiling water for 10-15 minutes; it should show no deformation, no color fading, and the water should remain clear. Counterfeits may soften, fade, or even make the water cloudy. A burn test can also be performed (operate with caution): genuine products burn without black smoke and leave white ashes; counterfeits burn with black smoke, emit a pungent odor, and leave black hard residues.

When choosing food-grade silicone products, the key is to recognize certifications, carefully check the texture, inspect for odors, and conduct tests. Combining these four tips can help you avoid 90% of the pitfalls.

Clarifying needs can avoid blind consumption. Next, compare brands and reputations. Prioritize brands with good reputations, and learn about the actual performance of products, such as durability and whether they are prone to deformation, through real reviews on e-commerce platforms to reduce the cost of trial and error.

Materials and craftsmanship are the core of quality. High-quality products mostly use food-grade or scene-specific materials, with better high-temperature resistance and corrosion resistance. Advanced production processes ensure that products have uniform thickness and smooth edges. Do not blindly pursue low prices. Low-priced products may use recycled materials, which have potential safety hazards. Instead, balance price with safety and durability, and choose silicone products with “matching price and quality”.

Usage and maintenance also affect cost-effectiveness. Although such products are durable, they should avoid usage beyond their applicable range, such as high-temperature frying. For cleaning, use mild detergents and soft tools to prevent surface scratches. When storing, keep them in a dry and ventilated place, away from sharp objects and direct sunlight to extend their service life.

The key to choosing cost-effective silicone products lies in “needs + quality identification + reasonable maintenance”. Avoid low-price traps, focus on material safety and brand reputation, and then extend the service life through correct usage, so that every penny spent is worth it. If you have bulk purchasing or customization needs (such as kitchen supplies, maternal and infant accessories, industrial seals, etc.), please feel free to send a private message or call for a quote! Inform us of the specific usage scenarios, purchase quantity, and customization requirements, and we will provide high-quality silicone product solutions, tiered quotations, and sample trials to help you select products efficiently and reduce costs while increasing efficiency!

The high-temperature resistance limit of silicone rubber: How much do you know?

The high-temperature resistance limit of silicone rubber: How much do you know?

From performance to application, revealing the core secrets of high-temperature resistant materials

Silicone rubber, as a commonly used composite material in industrial and household fields, its excellent high-temperature resistance has always been a core advantage, but what is its high-temperature resistance limit? This question is directly related to material selection and application safety. This article will analyze it from three aspects: the nature of performance, application fields, and limit parameters.

This polymer with a siloxane bond (Si-O) as the core structure has a temperature resistance range from -60℃ to 230℃. Special formula silicone rubber can break through the high-temperature resistance limit of 300℃, and can maintain elasticity and wear resistance even under extreme temperatures. Its heat-resistant mechanism comes from the stable siloxane chain structure, which can resist high-temperature oxidation. Low thermal conductivity can reduce heat transfer, and a small expansion coefficient can ensure dimensional stability, making it stand out in many fields.

In the automotive industry, it is used for engine gaskets and cable protective sleeves, which are resistant to high temperatures; seals and insulating materials in the aerospace field need to withstand extreme temperature changes; rice cookers, oven gaskets in household appliances, as well as high-temperature disinfection components of medical devices and protective materials for electronic components, all depend on its heat resistance and safety.

Divided by heat resistance grade, the high-temperature resistance limit of standard silicone rubber is 230℃. High-performance models can reach a heat resistance of more than 300℃ through silicon-fluorine mixing or silicone modification technology. Fire-resistant types can withstand high temperatures in flames for a short time, meeting extreme protection requirements. The flexibility of silicone rubber formulations allows its high-temperature resistance limit to be adjusted as needed, making it an indispensable material solution in many industries.

Understanding the high-temperature resistance limit of silicone rubber is the key to accurate selection. With product upgrades, this material combines heat resistance, low-temperature resistance, chemical stability, and biocompatibility, and its application boundaries will continue to expand, providing reliable support for more high-temperature scenarios.
