Envalior says that actuators are a key utility space for Stanyl polyamide 46 compounds. Supply: Envalior
As firms more and more acknowledge that PFAS, or per- and polyfluoroalkyl supplies — also called “ceaselessly chemical compounds” — could be dangerous to people, they’re searching for options. Envalior has been engaged on different supplies that can be utilized in high-wear and high-friction functions akin to robotic actuation.
The Dusseldorf, Germany-based firm stated it acknowledges the rising demand for polytetrafluoroethylene (PTFE)-free supplies which might be sustainable, economical, and long-lasting. The problem for tribology element producers lies in the truth that no additive options carry out as successfully for put on and friction wants as PTFE, famous Envalior.
“If regulatory restrictions are enacted, many plastics that have been enough up to now … could fall in need of efficiency necessities when PTFE is eliminated or changed with different components,” it stated.
Envalior was established in 2023 via the merger of Lanxess Efficiency Supplies and DSM Engineering Supplies. The corporate claimed that it’s a world chief in engineering supplies, with greater than 4,000 workers worldwide.
It makes a speciality of creating high-performance supplies, together with PA6, PA66, PBT, PA46, PPS, TPC, PET, PA4T, PA410, and thermoplastic composites. Envalior stated it focuses on markets together with mobility, electrical and electronics, and client items.
Envalior develops high-performance PTFE-free supplies
Envalior stated Stanyl can fulfill efficiency necessities with out requiring PTFE, making it appropriate for timing techniques, actuator gears, bearings seals, and bushings amongst others.
“Our Stanyl portfolio presents clients many choices to satisfy excessive efficiency traits whereas assembly authorized and application-specific necessities,” stated Adnan Hasanovic, technical skilled for tribological functions at Envalior. “Stanyl is ready to provide to producers ductility, strong tribological efficiency and design freedom by way of extruded elements.”
“As industries push the boundaries of efficiency, effectivity, and sustainability, the selection of supplies utilized in put on and friction functions is changing into extra complicated and significant,” asserted Envalior. It cited its Stanyl polyamide 46 (PA46) portfolio.
“Our high-temperature polyamides typically pave the best way for improvements in a variety of industries,” added Hasanovic. “For instance, they’re more and more changing metals and fewer sturdy plastics in gears, bearings, seals, and bushings for the automotive business, robotics and family home equipment.”
Stanyl PA46 continues to be a high-performance materials at elevated temperatures, stated Envalior. Resulting from its excessive crystallinity, it presents a mixture of:
- Superior fatigue and put on resistance
- Excessive affect and weld line energy
- Glorious circulate conduct for thin-walled designs
- Excellent stiffness and creep resistance at elevated temperatures
These properties serve put on and friction functions effectively, particularly the place excessive torque, velocity, and temperature are concerned, in keeping with the corporate. In contrast with conventional supplies like PA66, POM, PPS, PPA, Stanyl can delivers greater efficiency and considerably decrease price in comparison with plastics like PEEK, it stated.
New gears are light-weight, sturdy, and quiet
Growing adoption of robotics and electrical automobiles (EVs) and developments in family home equipment have led to new necessities for gearbox and bearing elements.
Within the discipline of robotics, force- and power-limited robots, also called collaborative robots or cobots, are touted for his or her capability to work safely alongside people. Nevertheless, conventional metallic elements of cobot gears can pose occupational security dangers on account of inertia and weight, offering a possibility for different elements.
In EVs, techniques akin to electrical energy steering, brake boosters, and thermal administration valves require compact, light-weight actuators that ship excessive torque and are dependable over the long run, even at excessive temperatures. Equipment producers are more and more changing metallic gears with plastic options to enhance manufacturing effectivity and product efficiency.
Envalior stated Stanyl meets all these calls for by enabling:
- Weight discount: As much as 40% much less materials utilization in comparison with PPS and PPA, leading to lighter, extra compact gears
- Noise discount: As much as 10 decibel decrease gear noise than metallic options, enhancing noise, vibration, and harshness (NVH) traits and enhancing the person expertise
- Excessive-temperature efficiency: Dependable operation at temperatures as much as 180°C, crucial for turbo actuator gears and different high-load functions
Envalior stated its superior gear-testing capabilities simulate real-life situations, serving to producers choose the optimum materials grade and cut back expensive re-testing and re-molding.
Stanyl supplies high-speed possibility for bearings
Bearings in EVs face excessive situations on account of compact motor designs and excessive rotational speeds, which ends up in excessive temperatures. Stanyl compounds allow thin-walled, light-weight designs that keep mechanical integrity beneath excessive centrifugal hundreds and rotational speeds as much as 30,000 rpm, stated Envalior.
In contrast with PA66, the compounds can cut back half deformation by about 20%, whereas additionally resisting chemical ageing from automotive lubricants, the corporate defined. Stanyl is more and more utilized in bearing cages to exchange metals and different polymers, providing:
- Low creep deformation: It may possibly cut back cage deformation that outcomes from excessive speeds and excessive centrifugal forces.
- Excessive ductility: Stanyl, which was offered at Ok 2025, can cut back danger of cage fracture and cage scrap charge in the course of the bearing meeting course of, stated Envalior.
- Excessive weld line energy: The fabric can cut back failure danger in complicated cage designs.
- Quick manufacturing cycle occasions: Excessive circulate and crystallization velocity allow environment friendly manufacturing.
- Chemical resistance: Stanyl can face up to publicity to the oils and greases utilized in automotive environments.
Envalior stated it helps bearing producers with superior simulation instruments, together with mildew circulate and finite ingredient evaluation, to make sure optimum design and efficiency beneath real-world situations. The corporate supplies detailed data on its supplies in MaterialAdvisor, which supplies digital instruments and companies that clients can use to search out, choose and consider supplies.
