In recent years, with the development of baby care products, kitchenware and the medical and health sectors, the demand for food-grade silicone products that are safe and resistant to high and low temperatures has grown rapidly. Guangdong, as an important cluster of the silicone product industry, has gathered many factories with relevant qualifications.
As a purchaser or brand owner, when faced with numerous options in Guangdong, one not only needs to find factories that can produce these products, but also has to identify reliable suppliers with mature production techniques and those that have passed safety certifications both domestically and internationally.
Today, we will introduce several notable food-grade silicone and liquid silicone product factories in Guangdong for your reference.
I. What is food-grade silicone?
Food-grade silicone refers to a type of silicone material that can come into contact with food, is non-toxic and odorless, and has stable chemical properties. It mainly has the following characteristics:
Resistant to high and low temperatures (-40℃ to 230℃)
Soft and with good elasticity
Does not absorb oil, easy to clean
Guangdong has established a relatively mature silicone rubber industry chain around cities such as Dongguan, Shenzhen, Guangzhou and Jiangmen. It is one of the regions in China that started producing silicone rubber products earlier.
II. Characteristics of Liquid Silicone Rubber (LSR)
When it comes to food-grade silicone products, liquid silicone rubber (LSR) must be mentioned. LSR is a fast-curing material catalyzed by platinum. Compared with traditional solid silicone rubber, it has several notable differences:
Solid silicone: During the molding process, a vulcanizing agent needs to be added and the mold is opened for material injection.
Liquid silicone rubber: No additional vulcanizing agent is added during molding. The material is sealed and injected, and it has good fluidity.
The advantages of liquid silicone rubber are:
Higher safety: Platinum catalytic system, no by-products during the sulfidation process, meeting food-grade requirements
Higher precision: Excellent fluidity, suitable for manufacturing products with complex structures and precise dimensions, such as baby nipples, medical tubes, high-permeability seals, etc.
High forming efficiency: Fast reaction speed, short forming cycle
High transparency: Suitable for products that require good light transmission.
III. Key Certifications for Food-grade Silicone
If your product is intended for export or for sale in the high-end market domestically, the following certifications are important references:
US FDA certification (21 CFR §177.2600)
This is a common requirement for exporting to the US and North American markets, stipulating that the total migration amount of silicone rubber under simulated food contact conditions should not exceed 0.5%.
2. EU and German LFGB Certification
This is widely regarded as a relatively strict food-grade standard. It not only tests the total migration amount but also includes sensory tests, requiring that the product does not cause any off-flavors to the food.
IV. Factories worth noting in Guangdong region
Here are several factories in Guangdong region that have the production capacity for food-grade silicone and liquid silicone, for your reference during the procurement process:
Jiangmen Hongxiangda Silicone Rubber Products Co., Ltd.

High compatibility: From sample production to mass production, the delivery period is stable, the after-sales response is quick, and OEM/ODM customization is supported.
Applicable products: Baby products (nipples, teething rings), kitchen utensils (silicone spatulas, baking molds), medical accessories, highly transparent seals, electronic buttons, etc.
2. Dongguan Siqi Rubber Technology Co., Ltd.
Location: Dongguan, Guangdong
Introduction: Siqi Rubber was established in 1999. The factory covers an area of over 46,000 square meters, equipped with a dedicated liquid silicone rubber workshop, and has more than 500 employees. The products are applied in fields such as medical devices, household appliances, baby products, and food machinery, and possess strong scale and production capacity.
Advantages: Large scale, complete equipment, suitable for large-volume orders.
3. Guangzhou Hongtu Silicone Rubber Products Co., Ltd.
Location: Guangzhou, Guangdong Province
Introduction: Comprising R&D, production and sales, the products are certified as food-grade by FDA, LFGB, etc. It is equipped with a dust-free workshop and has an annual output value of 30 million yuan. It has certain accumulation in food-grade silicone daily products.
Advantages: Located in Guangzhou, with convenient transportation and good compatibility.
V. How to Select Reliable Suppliers?
Apart from the above-mentioned ones, there are other good factories in Guangdong. You can evaluate them based on the following four aspects:
Check the qualification certification: Confirm whether there are international food-grade certifications such as FDA, LFGB, etc., as well as ISO system certifications.
Examine the equipment and the workshop environment: Whether there is a liquid silicone injection machine and a dust-free workshop directly affects the stability of the product.
Examine the craftsmanship accumulation and team experience: Understand the mold design capabilities and raw material application experience of the factory
Evaluate the service and cooperation level: From sample production to mass production, check whether the communication is smooth, whether the delivery schedule is stable, and whether there is adequate after-sales support.
Conclusion
There are many factories in Guangdong that produce silicone materials, but only a few can consistently produce export-grade, food and medical-grade liquid silicone products. Therefore, a careful selection process is still necessary for such suppliers.
