The bands of UV LED are concentrated in 365nm, 385nm, 395nm and 405nm, and the absorption of phosphine oxide photoinitiators in these bands is relatively strong, so they are widely used in the application of UV LED. One of the most representative photoinitiators is TPO, which not only causes high efficiency but also does not yellowing. In 2018-2019, due to the vigorous rise of UV LED curing and China's " Blue-Sky Scheme’, the supply of global TPO was very tight, and the price had been soaring, with the highest unit price exceeding 50USD/KG. The revenue and profits of photoinitiator manufacturers were in record highs because of the skyrocketing price of TPO. In recent years, the continuous expansion of do......

ECure TMO (di-p-tolyl(2,4,6-trimethylbenzoyl) phosphine oxide, Cas No.: 270586-78-2) is a phenylphosphine oxide-based photoinitiator that has gained attention as an alternative to TPO in UV and LED curing applications. It's particularly recognized for its lower environmental impact, making it a suitable choice for formulations in industries where regulatory compliance and sustainability are key considerations.   Here’s a detailed overview of ECure TMO:   Chemical Structure and Properties:   Chemical name: di-p-tolyl(2,4,6-trimethylbenzoyl) phosphine oxide   Formula: C24H25O2P   Molecular Weight: 376.4   CAS No.: 270586-78-2   Structure: It features a phosphine oxide gr......

The impact of Generative Artificial Intelligence (GAI) on chemical new materials is multifaceted and significant. GAI has revolutionized various aspects of material science, including design, synthesis, characterization, and optimization. Here are some key ways in which GAI influences chemical new materials:    1. Material Design GAI-powered algorithms can analyze vast amounts of data on existing materials and their properties, enabling researchers to identify patterns and correlations that might not be apparent through traditional methods. This facilitates the development of novel materials with tailored properties for specific applications.     2. Virtual Screening GAI models can rapidly......

5 September 13, 2024, the Office of the US Trade Representative (USTR) confirmed hiked tariffs on Chinese imports, including EVs. Per the USTR, those increased duties include a 100% tariff on Chinese-built EVs, a 50% tariff on solar cells, and 25% on steel, aluminum, EV batteries, and other critical minerals. The tariffs above will go into effect on September 27, but there are more to follow. A determination by the USTR posted on Friday also stated that the US would impose a 50% duty on Chinese semiconductors, divided into two new categories – polysilicon used in solar panels and silicon wafers. Both those tariffs are expected to go into effect in 2025. The USTR did not amend the tariff increase from zero......

On January 23, 2024, the European Chemicals Agency (ECHA) updated the list of candidate Substances for SVHC (Substances of Very High Concern), adding five substances to the list. Including 2 - (4 - methyl benzyl) - 2 - (dimethyl amino) - 1 - (4 - morpholine phenyl) - 1 - butyl ketone, namely Photoinitiator 379. It is only seven months since the photoinitiator TPO was included in the SVHC candidate list by ECHA in 2023. So far, the SVHC candidate list includes a total of 30 batches of 240 substances. https://echa.europa.eu/candidate-list-table All companies that produce, sell and use chemicals in the EU are expected to meet their obligations under the ECHA regulation. If the content of SVHC substances in articl......
