Colour adjustment for bio-based plastics

Plastics made from renewable raw materials are becoming increasingly popular because they can significantly reduce the carbon footprint of the end product and offer equivalent technical properties to petrochemical comparators. If the manufacturer does not plan to obtain biodegradability certification for their product, our TEKOLEN® range of masterbatches is the perfect choice, regardless of whether you use our carrier materials or a customer-specific polymer, as there are no restrictions on colour formulation.

We would be happy to develop your desired colour – precisely, reliably and in the highest quality!

Colour adjustment for biodegradable plasticse

If the biodegradability of your plastic product is important, e.g. according to standards such as those of TÜV Austria (‘OK compost HOME’, ‘OK compost INDUSTRIAL’ or ‘OK biodegradable’), then our BIOCOLEN® masterbatch series is the perfect choice. Depending on the standard and the seal to be achieved, limit values must either be complied with or entire groups of substances must be excluded!

This is exactly where our BIOCOLEN® masterbatch comes in, as the colour formulation is based on organic and differentiated inorganic pigments. We also avoid the use of heavy metals, so that the masterbatch is either completely free of heavy metals or remains below the communicated limit values. Finally, the finished BIOCOLEN® masterbatch is tested again in our analytical laboratory in the target dosage for the end product.

This ensures that our customers pass standard tests when using BIOCOLEN®!

On request, we are happy to use customer-specific carrier materials and test compliance with the desired and predefined limit values in our extensive analytical laboratory for subsequent certification of the end product.

Additives for BIOCOLEN® products

In the field of additives, we use bio-based raw materials wherever possible for masterbatches in the BIOCOLEN® range, such as our dispersing aids or lubricants. For every enquiry, we check whether we can use alternatives to non-renewable standard additives for our formulation. In doing so, particular attention must be paid in advance to the certification to be achieved for the end product, as not every combination of additives is suitable for all certifications. Here you can rely on the support of our MATERIAL SCIENCE department, which checks every BIOCOLEN® formulation in advance for possible certification obstacles.

Optical effects with BIOCOLEN®

By adding certain substances, it is possible to give plastics a new optical quality. Combining plastic with flakes, cellulose fibres, particles and a suitable texture creates a visually interesting and high-quality surface. These effects also emphasise the ecological impact of the material, and the resulting products stand out clearly from standard plastics without any special effects.
