Which is more environmentally friendly, PVC or silicone?

In today's increasingly environmentally conscious world, environmental friendliness has become an important consideration when choosing materials. Who is better on the environmental track than PVC and silicone, two common materials? Today we will give you a deep analysis.

1. Analysis of the Environmental Protection Status of PVC. PVC, also known as polyvinyl chloride, is widely used in industry and daily life, such as plastic pipes, doors and windows, and wire sheaths. But its environmental issues cannot be ignored. During the production process, PVC requires the addition of plasticizers, stabilizers, and other additives. Some plasticizers, such as phthalates, have been shown to have a disruptive effect on the human endocrine system and may pose a health hazard. Moreover, PVC contains chlorine, which releases harmful gases such as hydrogen chloride during combustion, polluting the air and corroding equipment; Abandoned PVC products degrade slowly in the natural environment and may release harmful substances into soil and water bodies, affecting ecological balance.
 

2. The environmental advantages of silicone are fully demonstrated. The main components of silicone are silicon dioxide and organic silicon polymers, which have stable chemical properties and are non-toxic and odorless. It has passed ROHS certification, which means it does not contain harmful heavy metals such as lead, mercury, cadmium, etc. The production process of silicone is environmentally friendly, and the curing process does not produce toxic by-products, without the need to add harmful additives. From a usage perspective, it is resistant to high and low temperatures and will not decompose or release harmful substances even at extreme temperatures ranging from -60 ℃ to 250 ℃, ensuring high safety. Widely used in food contact and medical fields, such as silicone kitchenware, baby pacifiers, medical catheters, etc. After disposal, silicone can be recycled and reused, reducing resource waste and landfill waste; Even if naturally degraded, it will not produce harmful substances and is environmentally friendly.

If you are looking for environmentally friendly materials and pursuing a green and healthy lifestyle and production method, in most cases, silicone is the better choice. In the current emphasis on environmental protection, choosing more environmentally friendly materials is your contribution to the sustainable development of the earth.
