Lehvoss Launches Highly Resilient CF-reinforced PA 66 for Automotive Gear Wheels

Plastic gearing in the automotive industry is increasingly being subjected to extremely demanding applications having higher loads and operating temperatures. Lehvoss North America has responded to this trend by developing new thermoplastic compounds that make it possible to produce gear wheels that are more resilient when compared to acetal, nylon, and PBT even at elevated temperatures.

New LUVOCOM® 1-8181 and LUVOCOM® 1-8520 compounds polyamide 66 fortified with carbon fibers and impact modifiers have been developed for gear wheels subject to high stresses. The strengths of these compounds at room temperature and at 120°C (240°F) have been increased by approximately 80% compared with standard polyamide 66 compounds. As an additional benefit, these new materials also exhibit an increased impact strength that meets or exceeds the requirements of many gear wheel applications. Depending on the service life of the component, the continuous operating temperature is 120°C (240°F) and up to 150°C (302°F) for short periods. “This combination of properties expands the engineering envelope for ultra-high performance plastic gearing,” explained Lefteris Valsamis, General Manager, Lehvoss North America.

Because of their technical and economic advantages, plastic gear wheels are currently displacing conventional metal designs in many industrial applications. In addition to their good processing characteristics, excellent design freedom, and mass production cost effectiveness, plastics also offer benefits such as high noise insulation, weight reduction, functional integration, and chemical resistance. Incorporating lubrication into the materials leads to an improvement in the tribological properties of plastic gear wheels which also contributes to a cleaner operating environment due to the elimination of external lubrication. Ultimately both higher performance and lower maintenance costs are achieved. “We offer formulations to create tailor-made compounds meeting the customer’s exact engineering requirements” said Valsamis.

PlastiComp Reveals Enhanced Aesthetic Capabilities of Nylon 6 & 66 LFT Composites

PlastiComp, Inc., among the global leaders in long fiber thermoplastic (LFT) materials and technologies, recently revealed the enhanced aesthetic capabilities of its Velocity® high flow nylon long fiber reinforced composites. The products simplify the injection molding of high fiber content LFT components by more easily producing the smooth, fiber-free finish desired on external surfaces.

PlastiComp developed its Velocity series of high flow nylon (polyamide) 6 and 66 LFT composites to facilitate easier and quicker molding of high glass or carbon fiber content materials. Standard LFT materials with fiber loadings of 50% or above exhibit high viscosity characteristics which can make them problematic to mold, especially in thin wall sections.

“What was originally a side benefit of improving flow has turned out to be a very desirable attribute of our Velocity long fiber products,” said Eric Wollan, business development manager at PlastiComp. “As the use of LFT’s progresses from industrial goods and internal structural elements to consumer goods and exposed housings, their appearance and surface finish has become a more important selection criteria.”

With standard high fiber content materials, higher molding temperatures are required to obtain a resin-rich surface, which results in slower cycle times and increased operating costs. When using PlastiComp’s Velocity long fiber grades, enhanced, fiber-free surfaces are obtainable at 30-40°F (17-22°C) lower processing temperatures. A smooth to the touch, resin-rich surface free of fibers makes colors appear more vibrant and is capable of holding finer embossed details – such visual characteristics are important to establishing high product quality perceptions among consumers.

“The superior surface finish of our Velocity LFT products virtually eliminates the need for any type of secondary finishing operations and it’s possible to achieve a near class-A surface finish with polished molds,” said Wollan. “Combining these aesthetic benefits with Velocity’s capabilities for producing thinner wall sections that facilitate more complex designs while utilizing less material and PlastiComp has long fiber reinforced materials that are ready to take on a new generation of applications.”

Why BioPlastics / BioChemicals when Crude Oil is Crashing ?

Bio Plastics are not only an alternate to fossil based plastics but also they are going to reduce greenhouse gas emissions and litter on the environment.
The biodegradation by microorganisms not only helps the soil but also act as a fertilizer. At present nearly 4%-5% of fossil oils are being used to produce all types of fossil based plastic materials for various applications.In recent days the world has witnessed the over dependence on fossil based plastics, but the fluctuating crude oil process along with the environmental concerns has slowly started the recognition and need for bio-based products.

A number of renewable chemicals have emerged in the last 5 years with the potential to enable traditional polymers while opening the path for newer materials using renewable food, especially non-food biomass as opposed to PetroChemicals. There has been a new wave of bioplastics entering the high-end consumer products such as auto-parts in TOYOTA,MERCEDES, FERRARI, and MASERATI; the field is continuously and rapidly evolving.

 The latest developments in PLA, PHA ,PEF and bio-sourced nylons,bio-PET and polyester show the entry of Bio plastics into newer applications in the automobile, electronics,medical, packaging and disposable products.
