SABIC’s ULTEM Resin Provides Lightweight Comfort for Hearing-impaired and Multi-Language Users of LLVision’s Augmented Reality Eyeglasses

Hearing loss compensation and spoken language translation can now be provided using an unlikely yet elegant technology – augmented reality (AR) eyeglasses from Beijing LLVision Technology Co., Ltd., which display voice translations in text on the lenses in real time. The company’s LEION Hey glasses feature legs (or temples) molded from SABIC’s tough, lightweight and inherent, non-halogenated flame-retardant ULTEM™ 1000 resin. ULTEM resin enables thin-wall molding of the hollow legs, which contain both a lithium-ion battery and a computer chip to enable rapid, multi-language translations. SABIC’s innovative material helped LLVision minimize the weight of the legs to give users all-day comfort, while providing high strength that enables key components to be integrated into the legs with maximum functionality.

“At the beginning of the design phase, we set a goal to make the lightest AR glasses on the market,” recalled Mr. Liang Xianglong, Co-Founder and Leader of Hardware Department of LLVision. “Every gram mattered to the comfort of our customers. However, with all the components required for AR glasses, including the optical module, microphone and computer chip, it was a difficult challenge. After comparing and testing materials from more than 20 suppliers globally, we found SABIC’s ULTEM resin to be the lightest, with additional advantages of strength, resilience and inherent, non-halogenated flame retardance. With the help of ULTEM resin, we lowered the overall weight of our LEION Hey glasses to just 79 grams, or 2.8 ounces.”

According to the World Health Organization, about 1.5 billion people (nearly 20 percent of the global population) live with hearing loss – a number that could rise to 2.5 billion by 2050. Another trend is the growing need for international communications that has arisen with the loosening of COVID-19 restrictions. The LEION Hey glasses can enable individuals to cope with both scenarios. They can help avoid the challenges of hearing in noisy environments or lip-reading when people are wearing masks. Also, they can facilitate communication in multilingual work environments and enable more-active business and social interactions.

LLVision employs automatic speech recognition technology and artificial intelligence to create, stream and display voice translations in milliseconds. The computer chip integrated in the legs of the glasses translates voice input into text data. The glasses connect wirelessly to a smartphone app that handles user authentication.

Lighter Legs
During LLVision’s selection process, ULTEM resin surpassed incumbent materials used for eyeglass legs, such as amorphous polyamide (PA) resin. SABIC’s polyetherimide (PEI) material provides a balance of ductility and stiffness that enables thin-wall molding to cut weight by up to 30 percent vs. PA and provide more space for embedded components. This specialty resin also provides better dimensional stability than PA for efficient assembly, and delivers combined stiffness and strength that allows the legs to clamp securely to the wearer’s head. ULTEM resin’s flame retardance enhances the safety of devices that incorporate electronic components, and the non-halogenated formulation avoids the use of chlorine and bromine, which are associated with adverse health and environmental effects.

ULTEM 1000 resin is an unreinforced, general-purpose grade offering high heat resistance, high strength and modulus, and broad chemical resistance. It is rated for fire safety under the UL94 V0, V2 and 5VA standards. SABIC supplies the material to LLVision in a custom gray color. In addition, SABIC has a broad portfolio of other materials well suited for eyeglass frames and legs depending on customers’ design needs.

“LLVision’s AR smart glasses are a novel and effective way to help people communicate more easily and accurately,” said Scott Fisher, director, ULTEM Resins & Additives for SABIC’s Specialties business. “Our high-performance ULTEM resin, which has been chosen for eyewear applications for more than a decade, helped the company address key product design and manufacturing challenges. Subject to user testing, any maker of AR or conventional eyewear can benefit from the light weight and high-strength properties of ULTEM resin. We look forward to working with LLVision on a next-generation version of the LEION Hey glasses using a certified renewable, bio-based grade of ULTEM resin.”

Stopping Plastic Leakage Into the Environment: Borealis Supports Ecopost to Drive Circular Economy in Kenya

• Borealis and Ecopost announce a collaboration to drive circular economy and support marginalized communities in Kenya.
• Borealis will specifically support Ecopost’s activities in capacity building, training and engaging more waste collectors as well as the formalization of their work by funding entrepreneurial start-up kits for the youth and women groups.

Nairobi, the capital city of Kenya, generates more than 2,400 tons of solid waste every day, in entire Kenya this is estimated to be more than 22,000 tons of waste per day. Furthermore, the country faces challenges with poverty with 36% of Kenyans living below the poverty line, earning less than US$1.90 a day, as well as is highly exposed to deforestation with only 6% of the country’ surface covered by forest, which is being further degraded by increased demand for building materials.

Ecopost addresses all these three challenges by driving a circular economy via collecting and recycling plastic waste through a replicable and scalable model, while at the same time creating jobs for operators, plastic waste collectors, and distributors. Its solutions divert plastic waste from open burning, dumping in waterways, sewers and landfilling by creating eco-friendly alternatives to fossil-based plastics for applications like fencing, signage & building material.

A key pillar of Ecopost’s business model is to work with marginalized youth and women groups who collect, sort, shred and prepare waste material for producing pellets and plastic lumber. These women are the most important people in the recycling value chain, while at the same time they are exposed to being underpaid for the waste they collect as middlemen selling the collected waste to waste recyclers typically capture the majority of the sales margin. Ecopost formalizes the informal waste picking community and incorporates training and capacity building across the value chain to achieve impact at scale and providing a fair and regular income to waste pickers.

As Borealis and Ecopost share the same vision to stop waste leaking into the environment through the enhancement of circularity and to create a positive socio-economic and environmental impact, both companies agreed on a collaboration where Borealis will fund Ecopost’s activities to boost waste recycling in Kenya and to promote a circular economy in line with the UN Sustainable Development Goals.

Borealis supports a portfolio of similar initiatives via the Borealis Social Fund, whose aim is to contribute to the social welfare of communities by financially engaging in three focus areas, being education and social integration, water and energy, as well as waste and resource efficiency.

Borealis will specifically support capacity building, training and engaging more waste collectors, as well as formalization of their work by funding entrepreneurial start-up kits for the youth and women groups.

“We very much welcome Borealis’ support of our activities to implement the selected modules to improve the informal waste collection.”, says Lorna Rutto, CEO of Ecopost Ltd. “The funds will make a positive impact to Ecopost as well as thousands of young people and women in the marginalized areas. It will be incredibly valuable in creating a more positive socio-economic and environmental impact.”

“Mismanaged waste adversely impacts livelihoods, human health and hinders sustainable development. Partnering with Ecopost not only complements Borealis’ vision towards a circular economy, but also helps reducing socio-economic differences, a key target area of the Borealis Social Fund.”, Markus Horcher, Director Sustainability & Public Affairs at Borealis comments.
