These marking methods require consumables, frequent tool changes and adjustments, regular quality control checks, and storage of the consumables. Percept™ anti-counterfeiting technology created an authentication method not visible to the human eye to help lower the financial result of fighting court cases, once the covert authentication was revealed. The concentrate also included the required color for the manufacturer’s branding and an additive for UV protection.

The GRS-certified materials produced at the Taoyuan site have been certified to contain a required percentage of pre-consumer or post-consumer recycled content. Customers can rely on Avient’s technology development and testing capabilities to get the most out of its recycled-content-containing materials as they move towards a more circular manufacturing model.” Unique technologies that improve the recyclability of products and enable recycled content to be incorporated, thus advancing a more circular economy

Quartz, or crystalline silica, is suitable for many purposes, while production via chemical processing is required to make a purer or otherwise more suitable product (e.g. more reactive or with lower particle size). The usual precautions, occupational exposure limits for inert dusts, industrial hygiene and occupational safety measure for handling chemicals should be observed. Observe the usual industrial hygiene measures.

Complete required compliance and ethics training and certifications. Q & A Q: I am required to do some business travel. At the same time, we are a very competitive company and want to be the best in the industry.
