The role of coloring in plastic molding

The role of coloring in plastic molding

The scramble for spaces among every notch is on the high. As new products throw their hart into the ring, the competition for attention will be on the increase. This is the reason why Rotational Molding should involve color in their design. If the products are not in colorful colors, the demand for such products will not be as high as it is expected to be.

Easy pigmentation

The best thing going for polythene is because it can be readily pigmented into several colors that will give the best appeal to the customers. It will be easy for plastic to absorb and reflect light and UV radiation from the sun. So what are the benefits of the ability to block light?

Let us look at the example of a tank produced from unpigmented polyethylene. This will allow the penetration of light. The result will be the opportunity for algae to grow and develop inside the tank.

Light blocking technology

When pigments are added at sufficient levels; it has the capacity to stop the growth of algae. If the layering of the pigments is solid enough; it will go all the way to totally prevent the growth of algae. The ability of the pigments differs from each other; it is, therefore, ideal to use the maximum addition of the pigment to achieve the results that mattered.

 The Absorption of UV rays

Most of the pigments used in the coloration of polyethylene for Rotomolding will do more than prevent the entrance of UV rays. It should be a pigment that has the ability to resist the weather which will make the material last longer. With this in place; you are not going to get a solution that will give you the best economic results on offer.

If you are looking for the best material that you can rely on in this direction, the typical pigment to consider is carbon black. When it is added at a rate of 2 – 2.5% and is well dispersed; you will get the best results on offer. You are going to achieve a lifespan of up to 10-20 years or above.

Properties for best pigmentations

We shall take a look at some of the must-have properties of a pigment that will enable it to be safe for use in the Rotomolded Plastic process.

The material needs to be safe. This is important when we consider articles that will come in contact with food materials. Health is the most important considerations here.

The environment is another factor that should be considered. You are going to get something that should be environmentally safe. When the article has reached the end of its useful life; it should be easily disposed without affecting the green of the environment. * The process should be thermally stable if issues relating to shrinkage are to be avoided. There should be the ability to resist fading in the final analysis.

The speed of the Custom Rotational Molding technology should be fast enough to achieve the best results.

The above are some of the considerations that you are to put into considerations if the best result is to be achieved.
