Roehm Introduces ACRYLITE® SunResist: Advanced UV Protection Meets Premium Performance

#Roehm proudly announces the launch of #ACRYLITE®SunResist, a breakthrough in capstock technology and the first of its kind under the ACRYLITE® brand, Roehm’s polymethyl methacrylate (#PMMA) products in the Americas.

Engineered for manufacturers who demand durability, aesthetics, and efficiency, ACRYLITE® SunResist sets a new benchmark for #outdoor applications including #windowconstruction, decking, outdoor furniture, #façades, and recreational components that must perform and look exceptional in high‑exposure environments.

Outdoor products face relentless UV, temperature swings, and abrasion. ACRYLITE® SunResist is a PMMA molding compound that has been formulated to create ultra‑thin co‑extruded protective layer that block harmful UV light up to 400 nm to help preserve color and surface integrity, reducing fading and degradation over time. Beyond its inherent UV and weather resistance, ACRYLITE® SunResist is designed for superior weatherability, maintaining color and gloss even under prolonged sunlight and moisture – ideal for components that must retain a premium appearance season after season.

ACRYLITE® SunResist elevates finished parts with a premium surface quality that offers precise gloss management, surface hardness and #abrasionresistance, as well as chemical resistance, enabling high end aesthetics without sacrificing robustness. Mechanical integrity is reinforced by high impact strength and heat stability, which help to prevent stress cracking, warping, or distortion at elevated temperatures.

For processors, ACRYLITE® SunResist was tuned for high flowability and a broad processing window. These attributes support smoother extrusion/co extrusion, help reduce scrap and improve overall productivity. ACRYLITE® SunResist demonstrates best in class adhesion to compatible substrates, designed to prevent brittle edges during cutting and to resist cap layer peeling. This is key for complex profiles, cut to size parts, and post fabrication operations.

Performance Indicators

UV and weather resistance: High UV absorbance up to 400 nm supports the product’s protective role against #photodegradation and color shift.

Color Fastness (Xenon Arc, ASTM G155 Cycle 1): Tests indicate a focus on minimizing perceptible color change over time in accelerated weathering, reinforcing the long term appearance goal for outdoor products.

Mechanical & Thermal Profile: Comparative framing highlights high flexural strength, notched Izod impact performance, and elevated heat deflection temperature, supporting resistance to bending, impact, and heat related deformation.

Today's KNOWLEDGE Share :How important have composite materials

Today's KNOWLEDGE Share

📢 Time to get technical... 📢

How important have composite materials been during the history of mankind? This schematic shows the relative importance of the four classes of materials (metals, polymers, composites, and ceramics) in engineering as a function of time! 😮

Composites have been part of human engineering for thousands of years.

But their role stayed relatively modest… until fiberglass changed the game.

Since the 1960s, composites have moved from niche solutions to core engineering materials. Enabling lighter structures, higher performance, and designs that simply aren’t possible with monolithic materials. 💡

That steady rise in relevance isn’t accidental.

It reflects how modern engineering thinks: optimize, tailor, and do more with less.

So let’s open the discussion:

What should define the next decade of composite materials and where should innovation focus next?

New plastic material could solve energy storage challenge, researchers report

In the race to lighter, safer and more efficient electronics — from electric vehicles to transcontinental energy grids — one component literally holds the power: the polymer capacitor. Seen in such applications as medical defibrillators, #polymercapacitors are responsible for quick bursts of #energy and stabilizing power rather than holding large amounts of energy, as opposed to the slower, steadier energy of a battery. However, current state-of-the-art polymer capacitors cannot survive beyond 212 degrees Fahrenheit (F), which the air around a typical car engine can hit during summer months and an overworked data center can surpass on any given day.

“Advances in the full systems for electric vehicles, data centers, space exploration and more can all hindered by the polymer capacitor,” said co-first author Li Li, postdoctoral scholar in Penn State’s Department of Electrical Engineering. “Conventional polymer capacitors need to be kept cool to operate. Our approach solves that issue while enabling four times the power — or the same amount of power in a device four times smaller,

Capacitors store less energy than batteries, but they charge and discharge their power much quicker. A mobile phone, for example, has a battery that charges from a power source. The energy it stores comes from many internal chemical-electrical reactions over a period of time that keep the phone working. Extra functions, like the flash on the phone’s camera, require a burst of energy. A capacitor is responsible for discharging that extra bang of power.

Most polymer capacitors fail at high temperatures because they are made of polymers with long chains of molecules that have low glass-transition temperatures, meaning the molecules turn from rubbery and malleable to brittle and fragile like glass at relatively low temperatures. Polymers can be found in natural materials, but are also synthetically produced to make thin, flexible films, thick, rigid plastics and everything in between. When the polymers and other material mix, their nanostructures — at the atomic level — form interfaces to varying degrees. They can leak electric charges, the researchers said, and the problem worsens at high temperatures.

“Normally, you can’t have both high energy density and high temperature tolerance in one dielectric polymer — we achieved both by mixing two commercially available high-temperature polymers.

The researchers combined #PEI, originally produced by General Electric and often used in pharmaceutical production, and #PBPDA, a polymer with high heat resistance and electric insulation. When mixed together at suitable temperatures, the molecular components of the polymers self-assembled into #3Dstructures, which the researchers used to make #thinfilms.

Today's KNOWLEDGE Share : Chopped UD (Forged Flakes)

Today's KNOWLEDGE Share

Chopped UD (Forged Flakes) is one of the most flexible composite formats we work with at COREX where we are combining continuous-fiber performance with molded-part design freedom.

Chopped UD is produced by cutting unidirectional thermoplastic tape into controlled flakes (typically 5–25 mm) and compression-molding them into near-net-shape parts. This creates a material architecture that’s both high-performance and highly designable.

What makes it special:

> Quasi-isotropic properties from the random orientation of the flakes

> Tunable anisotropy by orienting flakes in a preferred flow direction during molding

> Premium aesthetics: smooth, uniform surfaces suitable for visible parts

> Long fibers (10–25 mm), far longer and stronger than injection-molding compounds

> High fiber volume fraction (45–55%) for structural stiffness and impact strength

> Variable thickness within the same part, thin skins + reinforced zones molded in one cycle

> Integrated features, ribs, frames, bosses, and fixtures formed directly in the mold, eliminating secondary overmolding

> Fine geometric detail: sharp corners, inserts, and complex 3D transitions

> Circularity: flakes can be produced from reclaimed UD prepreg offcuts

COREX Materials is leveraging this platform across mobility, electronics, aerospace interiors, sports, and protection, where weight, durability, and manufacturing precision matter.

Chopped UD is not a downgraded material. It’s a programmable composite architecture combining our three pillars of Performance, Agility and Circularity.

New high-performance composites for aviation and drones take center stage at Envalior's JEC 2026 exhibit

Envalior, a global leader in sustainable and high-performance engineering materials, is putting the spotlight on its new Tepex® and UDea® composites for aircraft and drone manufacturing at JEC World 2026. The composites, many of which are bio-based, give manufacturers in these industries the opportunity to switch from thermoset to thermoplastic construction materials.

New polyphenylene sulfide and polyetherimide composites Tepex® dynalite: These materials are characterized by high temperature and chemical resistance as well as high intrinsic flame retardancy. Potential applications include aircraft interior parts, such as seat shells, paneling, partitions, and flaps.

High-performance Tepex® dynalite composites based on Envalior's EcoPaXX® (polyamide 4.10, PA 4.10): This material family is biobased and derived from castor oil. Thanks to the excellent adhesion between the reinforcing continuous glass or carbon fibers and the PA 4.10 matrix, it offers the highest strength and stiffness in Envalior's composite portfolio while having a low density. This makes it ideal for lightweight components in drones, such as rods and rotors.

Thermoplastic high-pressure vessel for storing hydrogen: The blow-molded tank liner is made of a Fuel Lock polyamide 6 compound and the reinforcing wrap is made of #EcoPaXX®PA410 UDea® tape, both from Envalior. The tank is easy to recycle. The strong chemical adhesion between liner and wrapping enables deep vacuum cleaning without collapse of the liner.The vessel exhibits a high mechanical strength at temperatures down to -40°C during rapid pressure changes, such as those that occur during fueling. Such #tanks can be used, e.g., in fuel cell technology for busses and trucks, and in #hydrogen transportation.

Rotation-molded liner for high-pressure hydrogen vessels: The #polyamide6 liner has an excellent inner surface with low porosity, comparable to that of blow-molded or injection-molded and then welded liners. The PA 6 compound enables the integration of metallic boss parts. As single-stage process, rotomolding is highly economical and results in liners without weld seams.

Protective sleeve for the rotor of an electric motor: The ultra-lightweight sleeve is made of UDea® tape and encloses the high-speed rotor. It is cheaper to manufacture in large volumes than its counterparts made of metal or #thermosetcomposites and, unlike the latter, is easy to recycle mechanically.

Bio-based child seat: The prototype, manufactured by the Fraunhofer Institute for Microstructure of Materials and Systems (IMWS), will be on display at JEC’s special exhibition Innovation Planets. The seat consists of a bio-based polyamide 10.10 composite Tepex® reinforced with flax fibers and is overmolded with a bio-based polyamide 11.
