Panacol Launches Fast-curable Epoxy Resin Adhesive for PCBs

Panacol launches Structalit® 5604, an extremely fast-curing adhesive which is specifically developed for bonding SMDs to printed circuit boards. The adhesive is based on epoxy resin and is, despite its high viscosity, suitable for jet application.

Offers Non-slumping Wet Adhesion:

Structalit® 5604 is a one-component epoxy resin adhesive that contrasts well with green PCB material due to its red color. This makes it possible to ensure visual inline inspection.

The one-component adhesive can be dispensed in production through jetting, valve dispensing or screen printing. Its ideally adjusted viscosity and high thixotropy index enable high-speed dispensing, precise dot profiles, and non-slumping wet adhesion prior to curing.

This adhesive is cured with heat. The thermal cure occurs within minutes, even at low temperatures. When fully cured, the adhesive is extremely temperature resistant. It can withstand short-term temperatures of up to 270°C, making it suitable for reflow soldering processes.

Suitable for Electronic Component Assembly:

Structalit® 5604 is particularly shock-resistant and durably adheres to FR4 printed circuit boards, metals, and epoxy-based molded materials. Due to its high glass transition range of >115°C, the adhesive is ideal for electronic component assembly.

It does not lose adhesion or softens at elevated temperatures. As Structalit® 5604 was developed specifically for use in electronics, it has high ionic purity and thus provides optimum protection against internal corrosion.

Panacol will present Structalit® 5604 at the BondExpo fair in Stuttgart, Germany.

Solvay Launches PA Grade with 100% Pre-consumer Recycled Content

Solvay, a producer of high-performance and sustainable polyamide 6.6 polymers, continues to drive innovation in its portfolio with the introduction of a new, specialized grade of Rhodianyl, made of 100% pre-consumer recycled polyamide, which is produced at its Santo Andre plant in Brazil.

The product has achieved SCS Recycled Content Certification, reaffirming Solvay's commitment to circular economy.

Verified Traceability of Manufacturing Process:

The internationally recognized third-party certification body SCS Global Services performed a rigorous audit to verify the traceability of the Group’s entire manufacturing process, including scrap management and the cutting-edge depolymerization reaction, which generates the final 100% recycled polymer.

Rhodianyl can be applied in engineering plastics for the automotive, small appliances and textile markets. It complements the Group’s wide range of innovative and sustainable polymers for today’s highest-quality textiles and fibers for the consumer goods industry.

"With over 70 years of expertise, Solvay has strengthened its position as a leading producer and supplier of high-performance and sustainable PA66 polymers. Certifying our recycling process is a significant step forward in meeting the stringent standards required by our European customers, who represent the primary market for this application due to the growing demand for recycled raw materials in the industry. We remain committed to delivering excellence and advancing sustainability in our industry," said Eduardo Girote, marketing director of Solvay's Coatis Global Business Unit.

“Solvay’s commitment to producing 100% pre-consumer Recycled Content Certified polymer makes a positive impact on both the environment and the supply chain,” said Nicole Munoz, VP of Environmental Certification Services at SCS Global Services. “Using recycled content reduces waste, saves energy, and gives materials a new life, rather than creating new materials."

This launch is also part of Solvay's ambition to reduce the environmental impact of its polyamide supply chain in Brazil. Several pioneering initiatives have been implemented in recent years, such as achieving a 95% reduction in CO2 emissions at the Paulínia factory, obtaining the Gold Certification from the Wildlife Habitat Council for biodiversity preservation in its industrial areas, and launching a pioneering program for recycling polyamide uniforms, among other initiatives.

Today's KNOWLEDGE Share:adiabatic heating

Today's KNOWLEDGE Share:

Do you know what "adiabatic heating" means when referring to Injection Molding ?

There's a bit of misunderstanding out there because there are two distinct aspects to consider.

"Adiabatic compression", the mere fact that polymers are locally quickly compressed at high P, leads to a temperature increase of abt. 5-10°C under 1000 b. This T increase relaxes back as you decompress. Just like in a perfect gas.

 

On the other hand, the very fast character of filling a cavity in I.M., leads to "quasi adiabatic conditions" for the heat transfer to the steel. As a result, any frictional heat generated by the shear (known as "shear-heating") turns into strong localized temperature increase in the high shear layers. Because there is almost no heat conducted out within that short time (precisely, what we call ADIABATIC conditions), one can quite accurately estimate total/average shear heating temperature increase from the flow pressure drop. A 1000 bar pressure loss (that is a direct energy measurement !) translates into abt. 40°C average increase in melt temperature.

China Has Approved More Than 50 Gigawatts Of New Coal Power

China’s coal output increased 9% to 4.5 billion tons last year.

China approved more than 50 gigawatts of new coal power in the first half of 2023.

The global energy crisis brought by Russia’s war in Ukraine has triggered a coal ‘spring’ in Europe.

Last year, China emerged as the world’s clean energy champ, with the country accounting for $546 billion, or nearly half, of the $1.1 trillion that flowed into the sector as countries everywhere rushed to beef up their energy security. But those mammoth investments will do little to change China’s tag as the planet’s biggest polluter, if the country’s fossil fuel investments are any indication. China approved more than 50 gigawatts of new coal power in the first half of 2023, environment group Greenpeace has revealed. China is building coal-fired power plants at a record clip as it tries to counter the effects of drought on hydropower production.

"China's government has put energy security and energy transition at odds with one another. Beijing has clearly stated that coal power will still grow at a 'reasonable pace' into 2030," Greenpeace's Gao Yuhe has told Reuters.

China’s coal output increased 9% to 4.5 billion tons last year, more than half the world's total, and is set to continue to rise in the current year as Beijing looks to offset a 22.9% decline in hydropower generation.

China is not the only country whose hydropower sector has been hit by climate change. Electricity generation from hydro power sources has fallen quite dramatically in Europe, North America and Asia in 2023 compared to the corresponding period in 2022 with overall global hydro generation now 3% below the 2019-21 average. Reduced supplies of non-emitting hydro power in these regions means that utilities are increasingly deploying other sources of dispatchable but more polluting power, such as coal and natural gas, to meet electricity demand.

Alarmingly, North America, the United States in particular, is the hardest hit region in the world. Drier than normal conditions in Arizona, Nevada, Washington and Colorado--all key hydro states--have led to a disastrous 17% decline in hydropower generation in the country. Mexico is not much better off, with output down around 15%.

The rest of Latin America is faring much better, with Brazil, the third largest hydro producer globally, recording a 3.4% growth in production while Colombia is experiencing a roughly 10% increase.

Asia--the global hydropower heavyweight accounting for ~43% of production--has not been spared by the hydropower crisis. China--the continent’s largest producer accounting for 30% of global capacity--has recorded a worrying 7.2% drop in output so far this year while India, the second largest producer, has seen production decline 5%. Vietnam, the ninth largest global hydro producer and currently in the throes of a massive heatwave, has seen output drop by 10.5%.
