Colouring recycled PVC
Delta Tecnic transforms recycled PVC products with its line of colour masterbatches. The company helps processors of recycled plastic to improve the colour of the products made from it and make them more attractive to the market. Whether in black, white or any other specific colour, PVC gets a second life that contributes to the preservation of the environment.
The latest market study on polyvinyl chloride by the consultancy Ceresana forecasts that demand for PVC will continue to grow and reach about 57.7 million tonnes worldwide by 2031. In Europe, more than 810,000 tonnes per year are already recycled, which is more than a quarter of all PVC waste. This means that the recycling rate of PVC is better than that of other plastics.In a world where sustainability and economy are crucial, Delta Tecnic offers innovative solutions to give plastic products that have reached the end of their useful life a second chance. With its line of colour masterbatches for recycled PVC, the company helps improve the colour of recycled products, making them more attractive to the market and contributing to the conservation of the environment.
The useful life of PVC in particular plays a fundamental role in the market. Manufacturers are constantly looking for ways to create durable and reusable products, using the right raw materials for this purpose. When a product ultimately reaches the end of its useful life, the aim is to give it a second chance through recycling.
Thermoplastics are generally recyclable, so the common use of the term “recycled” describes products that have been transformed and reintroduced to the market at the end of their initial useful life. Delta Tecnic is specialized in offering solutions through its colour masterbatches to help improve the final colour of recycled PVC products, whether in black, white or any other specific colour, giving the plastic a second life.
Three ways to recover the colour of recycled PVC
1) Plastic that is made up of different colours is usually transformed into black using carbon black concentrates.
2) For white PVC which is to be reintroduced in the same colour, it is important to note that due to thermal stress, the recycled product tends to yellow. For this reason, Delta Tecnic offers a range of white masterbatches containing titanium dioxide, in many cases custom made, that help to improve the final colour.
3) When a manufacturer wants to create parts in a specific colour, Delta Tecnic recommends separating the residual products by colour and making a specific masterbatch for each colour, thus improving the final colour of each part.
The company has been helping the PVC industry to incorporate colour in all its applications for more than 40 years. Waste managers purchase end-of-life products with the aim of reforming them as plastic. These recyclers shape the products into pellets with an extruder and the recycled compound is then sold to plastic parts transformers. In this way, Delta Tecnic supplies its special masterbatches to be introduced during the PVC recycling process to improve the quality of the final component.
The recycling rate of PVC is one of the highest
