Technological Breakthroughs and Policy Support: Bio-based Silicone Opens Up a Green New Track

Driven by the dual forces of the "dual carbon" goals and increasingly stringent environmental protection policies, China issued the National Food Safety Standard for silicone rubber Materials and Products in Contact with Food (GB 4806.16-2025) in September 2025. By tightening the limits on volatile substances and standardizing the raw material access list, this standard has indirectly paved a new path for the market penetration of bio-based silicone. Endowed with inherent core properties of low volatility, environmental friendliness and non-toxicity, bio-based silicone has gained a natural edge in compliance competition, emerging as a preferred solution under policy guidance.

As a green alternative to traditional petroleum-based silicone, bio-based and biodegradable silicone has seen its raw material substitution routes continuously expanded, with diversified applications of renewable resources ranging from castor oil and corn starch to rice husks. Food-grade products with a bio-based content of ≥60% have been successfully developed. Compared with traditional petroleum-based silicone, such products reduce carbon emissions by 35% and lower the migration of volatile substances to 0.3%. Catalyzed by both the industrialization of technologies and the upgrading of market demand, bio-based silicone has experienced explosive growth, been successfully incorporated into the sustainable procurement systems of leading enterprises such as Apple and Tesla, and gained recognition in the high-end market.

The medical field, as a core scenario for high-end applications, has an urgent demand for bio-based and biodegradable silicone. In niche scenarios including implantable medical devices, wound dressings and surgical molded seals, biodegradable silicone perfectly meets the stringent requirements of the medical sector by virtue of its excellent biocompatibility, precisely controllable degradability and stable mechanical strength.In the food contact field, relying on its outstanding safety performance, bio-based silicone has achieved rapid penetration growth in sectors such as baby products, baking utensils and food packaging, effectively alleviating the environmental accumulation pressure caused by traditional silicone waste.

As a professional silicone rubber manufacturer, Suzhou Menhow has always been keenly insightful into the industrial trends of bio-based silicone. With the continuous expansion of the company's application scenarios, we have gradually launched the technology introduction, product R&D and market promotion of bio-based silicone, steadily advancing the replacement of petroleum-based Lsr Silicone Product (liquid silicone rubber) with bio-based silicone. We are committed to empowering high-quality enterpris e development through green transformation and seizing the first-mover advantage in the new track of environmentally friendly new materials.
