Polymers are long chains of repeating molecules that are the main building blocks of plastics. There are many different types of polymers, each with their own unique properties and uses. Additives are chemical compounds that are added to polymers during the manufacturing process to enhance their properties or to make them easier to process. …

Our products are suited for a wide range of plastic materials, including polyolefins and engineering plastics. Besides processing aids, novel coupling agents, and modifiers from our BYK and SCONA brands, the BYK-MAX and RECYCLOBYK products play a major role in thermoplastics applications. Most of them are designed precisely for that purpose.

Recycling aromatic plastics, such as polystyrene (PS) and polyethylene terephthalate (PET), is complex and strongly sensitive to the process design and conditions due to the presence of polycyclic aromatic hydrocarbons and interunit C O and/or C C linkages. Herein, the upcycling process becomes crucial to attain high-value-added …

Talc powder enhances the thermal stability of plastics, preventing degradation during processing at high temperatures. It acts as a thermal insulator, dissipating heat and minimizing the risk of overheating or thermal damage to the plastic material. Talc's lamellar structure provides anti-blocking properties to plastic films and …

Anti-blocking additives reduce blocking at the surface of polymer films and other plastic articles to allow easier processing and handling. Traditional inorganic anti-blocking additives, such as silica or talc, work by reducing polymer to polymer contact and micro-roughening of the surface, but often affect the clarity of the polymer at higher ...

Suppliers: Blachford, Covia, Magris Talc. TESTING EQUIPMENT Used in R&D as well as Quality control Features: Measure properties of …

Processing. Some mineral fillers may be light and fluffy because of low bulk density, requiring special equipment and processing techniques to be added to and dispersed evenly in the polymer. Once encapsulated in the plastic, however, the compound pellets can easily be fed into an extruder or molding machine.

Plastic/polymer additives are chemical substances added during the plastic production process to improve the characteristics of the plastic in terms of performance, processability, and appearance. Common plastic additives include plasticizers, stabilizers, antioxidants, UV absorbers, fillers, and more. These additives can be combined …

Repelletizing will eliminate this problem and it allows for the regrind to be melt filtered to remove non-plastic contamination. Unfortunately this will add $0.12 to $0.20 per lb. For process stability grinders should be well maintained, blades sharp, cleaned properly, and screen working properly.

ID = 1.66) means that there is enough space in the process chamber to ensure a good dispersion and high throughput. The additive feed often poses a challenge in processing: if additives with a low melting point are added, they could already melt in the side stuffer. This would lead to a block-age in the side stuffer. The formulation consistency can
