CESA™ Light Additives Light Stability PRODUCT SELECTION GUIDE Exposure to the sun, heat, and oxygen through outdoor exposure causes the degradation of the polymer, resulting in yellowing, loss of melt strength, and loss of mechanical properties in most resins. You have the responsibility to conduct full-scale end-product performance testing to determine suitability in your application, and you assume all risk and liability arising from your use of the information and/or use or handling of any product.

Cesa™ Light Additives for Injection Molded Applications Sunlight in combination with heat and oxygen can induce degradation in plastics, causing detrimental effects on mechanical, optical, and other physical properties. You have the responsibility to conduct full-scale end-product performance testing to determine suitability in your application, and you assume all risk and liability arising from your use of the information and/or use or handling of any product.

Since PEI resin offers excellent resistance to heat and fire, and has very good dimensional stability, it is ideal for a variety of applications in industries such as aerospace, automotive, telecommunications and healthcare. You have the responsibility to conduct full-scale end-product performance testing to determine suitability in your application, and you assume all risk and liability arising from your use of the information and/or use or handling of any product.

APPLICATIONS Avient’s chain extenders for fibers can be used to boost the processing of recycled polyester for a variety of textile products, including: • Clothing and sportswear • Bags and backpacks • Home textiles and upholstery • Automotive textiles and insulation/heat management systems • Carpets and rugs WORKING PRINCIPLE As opposed to standard chain extenders, which usually branch the PET molecules, Avient’s chain extenders for recycled PET fibers extend the molecules in a linear way, which is more adapted to the reprocessing into fibers. You have the responsibility to conduct full-scale end-product performance testing to determine suitability in your application, and you assume all risk and liability arising from your use of the information and/or use or handling of any product.

A higher injection velocity is needed when processing Gravi-Tech due to the thermal conductivity of the material. 2. The shear heat comes from shearing the material. k = Thermal Conductivity Constant • ρ = Density • Cρ = Specific Heat Step 2 – Heat Transfer The next step is to calculate the heat transfer rate.

Therma-Tech™ Thermally Conductive Materials: Engineered materials that are lighter than metal and are easier to form, but do not compromise conductivity

If the heaters are on continuously, there is not enough heat being produced from shear. To increase shear heating, increase the screw rpm and back pressure. Increasing the back pressure increases shear heating of the material.

In addition to common environmental simulation or functional performance testing services, Avient can also conduct individualized testing and simulations in order to optimize material formulations, product performance, or design.
