Why is colorful tubing is more expensive than black tubing of the same size?


The difference in cost is explained by peculiarities in production technologies. In general heat shrinkable tubing goes through there stages: extrusion, sealing and blowing. When you start production of a tube that has a different color the remnants of the previous material should be taken out of the machine, so there are some non-recycled waste products that influence the price of the product.
