“Nothing Speaks against the Use of Recyclates for Demanding Components”

The quality of recyclates can be improved very well by means of suitable additives. An overview of the variety of products and their suppliers.

The quality of recyclates is seen as too low. Improvements are possible by using additives, as was shown by the exchanges during the Forum Plastic Recyclates.

Quite clearly, the central theme of this year’s conference  was additives for recycling materials.

Using the latest technological advances in flake sorting helps bridge the gap between supply and demand.

Mixed plastic waste: With about 180.5 million t polyolefins make up the lion‘s share of annual plastics production.

Quantum Leap in Recyclates Quality

The stabilization of used plastics is costly. Online measurement during compounding allows for stabilization directly in production.

Plastic waste often has a very different stabilizer content. This must be precisely determined in the recycling process. 

Determined Online, Recyclate Wins

Closed Material Loop Achieved with Technical Component

Material and manufacturing process optimized, CO2 saved: recycled wash cap from Pöppelmann K-Tech closes the loop.

Wash caps for the automotive industry are technically sophisticated products: They reliably protect the power electronics of vehicles from the ingress of water, dust, and dirt during the cleaning process. They often also have to be suitable for automated assembly. Pöppelmann K-Tech has succeeded in making these products significantly more sustainable.

For the production of wash caps for a well-known customer in the automotive industry, the plastics specialist uses a large proportion of post-industrial recyclates (PIR) from its own production. After use, the wash caps can be fully recycled again.

In this project, Pöppelmann K-Tech took over material development as well as the design of the wash caps, their production in the injection molding process, and testing and series production.

Reduction in Component Weight and Dimensional Stability

 For these articles with a diameter of 450 mm, a material blend is used that contains predominantly PIR as well as a smaller proportion of virgin material and post-consumer recyclate (PCR). The post-industrial plastics waste comes, for example, from sprue returns from Pöppelmann production. Another special feature is that the PCR consists of used wash caps returned to Pöppelmann by customers. The material is sorted, processed, compounded with appropriate additives and is then available as post-industrial recyclate PP-TV20. New wash caps are manufactured from it using the thermoplastic foam injection molding process. One advantage of the process is the reduction in component weight combined with the excellent dimensional stability of the article. At the same time, the clamping force required for the injection mold is also lowered.

The use of recycled materials and optimized production have achieved a serially manufactured article that closes the production loop and offers increased sustainability. The change in material reduces emissions by 5777 t CO2 eq. calculated over the complete life of the product – a decrease of 77 %.
