PVC=polyvinyl chloride, it is one of the most widely used Materials with large molecular chains of natural or fossil raw materials, produced by chemical or biochemical reactions. More. It is widespread mainly due to the easy and cheap production of the basic component, i.e. vinyl chloride. After the addition of various components, its properties can be well controlled, which is important for different types of products. It can be easily processed by all basic plastic manufacturing processes. It is highly biological, chemical and heat resistant. PVC can be well recycled, for which it is widely used. Its dangers lie mainly in its unprofessional disposal (as it can release harmful substances when improperly incinerated), in its presence in the environment (extremely long degradation time and the release of Microplastics is a general term for plastic fragments of various origins up to 5mm in size. Their existence is mainly associated with their presence i...) or in the possible release of certain additives and A plasticizer is a substance that is added to a material to make it softer and more flexible, to increase its plasticity, to decrease its viscosity, o...
