During processing, polymers often degrade due to oxygen and heat exposure which causes such things as discoloration, gels, and black spots. It is a specialized antioxidant additive that stabilizes polyolefins during processing—preventing the typical defects like discoloration, gels, and black spots—during initial, and future conversion steps and recycling loops. Sustainability Spotlight Recycle Solutions KEY CHARACTERISTICS • Designed for polyolefin recycling and to enhance circularity • Protects polyolefins against degradation caused by oxygen and heat during processing • Provides improved stability against oxygen degradation and discoloration • Stabilizes the polymer to reduce creation of new gels and black spots • Excellent performance at low dosage levels MARKETS & APPLICATIONS • Recycled polyolefins • Packaging, consumer & others • High-value polyolefin applications with recycled material content • Virgin polymers which will be recycled after the use phase Copyright © 2022, Avient Corporation.

Another color-related challenge is the multitude of different color streams of recycled PET, which can limit the uses for recycled colored PET. Fortunately, there is new technology that can analyze the color of the PET or rPET to be used for a new product and predict the range of colors possible for the end product. In many instances, these colored bottles may offer an outlet to utilize some of the less transparent rPET feedstock as the colorant can mask the original recyclate color.

Some common manufacturing options are pultrusion, resin injection, resin transfer molding (RTM) and filament winding. Design flexibility — Composites can be molded into complex shapes and textures at a relatively low cost. To start, it’s best to know the kind of environment in which your product will be and what kind of properties you need (e.g., heat or water resistant, hard or soft, color).

In the consumer applications, the elastomer performance needed is processability, colorability and softness. New colors, textures, designs, comfort – these and more are all compelling reasons to choose a product that features an overmolded TPE surface. The consumers’ preference for a soft touch, "warm" feel and a personalized color palette drives the use of TPEs in personal care products.

To correct this, raise both the mold temperature and process temperatures. Injection molding of thin wall parts requires a low viscosity TPE. Extrusion, blown film production or blow molding requires high melt strength.
