Polyvinyl chloride

PVC Plastic

PVC (polyvinyl chloride) is a rigid, strong thermoplastic with very high transparency and excellent chemical resistance. It can be thermoformed extremely well and is ideal for blisters, packaging, transparent covers and technical covers — especially wherever resistance to acids, alkalis and chemicals is required.

What is PVC plastic?

PVC plastic, short for polyvinyl chloride, has relatively high rigidity and strength. Due to its additional high transparency and resistance to various chemicals and substances, PVC plastic is often used in the packaging industry, medical technology and mechanical engineering.

Processing and thermoformability of PVC

PVC plastic stands out due to its very good thermoformability. In practice, PVC can be thermoformed without difficulty into a wide variety of shapes and designs with sharp contours. In post-processing, blisters made from PVC plastic can also be bonded and welded very effectively. In terms of processing and thermoformability, polyvinyl chloride is therefore a high-quality material.

Challenges of PVC plastic

Recycling challenges

PVC plastic presents challenges in the recycling process. During the energy recovery of PVC, environmentally concerning substances such as gaseous hydrogen chloride or heavy-metal stabilizers can be produced. For this reason, incineration plants are equipped with complex filter technologies that neutralize these substances and prevent harmful emissions.

Substitution with PET

Due to high energy costs, polyvinyl chloride is usually substituted with PET-A plastic whenever the application allows it. Nevertheless, PVC remains the better choice for specific applications with high chemical requirements.
