Core insight

Plastics born in the early 20th century are widely used in various fields around the world because of their low cost, strong plasticity and light weight. Global annual plastic consumption of 400 million tons, China more than 60 million tons. However, the harm of plastic is also increasingly prominent, the chemical structure is stable, the natural degradation takes decades to hundreds of years, about 8 million tons a year into the ocean, destroying the ecology and threatening human health. Some plastics contain harmful substances such as bisphenol A, which will be released during use and interfere with human endocrine and other systems.

In this context, silicone has become an ideal alternative to plastic. Silica gel is made of silicate and organosilicon compounds and is a highly active adsorption material. In terms of physical properties, it has good elasticity and flexibility, high and low temperature resistance (-60 ° C to 300 ° C), strong chemical resistance, most chemicals and solvents can not do anything about it, and most plastics use a narrow temperature range and are sensitive to chemicals. In terms of environmental protection, silica gel can be recycled, the degradation rate is relatively fast, and the residual pollution is less. In terms of safety, silicone is extremely low toxicity, easy to obtain food grade certification, tasteless and odorless, hypoallergenic.

This white paper will delve into the application of silicone to replace plastic in ten common scenarios to help reduce plastic and move towards a green future.

Ten application scenarios of silicone instead of plastic

Food packaging and storage scenarios

In the field of food packaging and storage, plastics are common, but there are many problems. Ordinary plastic packaging is difficult to degrade, easy to become "white pollution", and some will release harmful substances to food. Silicone has obvious advantages:
