Quadrant Engineering Plastic Products has extended its Fluorosint enhanced PTFE range with FDA-compliant and high-temperature grades for bearing applications.

According to the company, these latest additions – Fluorosint HPV and Fluorosint MT-01 – can outperform competing PTFE materials by up to 40 per cent on bearing performance measures and present new material options for engineers.

Food and Drug Administration (FDA) compliant Fluorosint HPV is a mica-filled high-performance bearing grade.

Parts made of this grade can withstand higher load and velocity while delivering better wear resistance, enabling longer part life compared with existing FDA compliant PTFE-based materials.

The product was developed to meet the demands of high-performance bearing applications where other, low-tech PTFE formulations would exhibit premature wear or can not perform.

Quadrant said these characteristics together with FDA compliancy for food and pharmaceutical applications open up interesting new options for engineers and manufacturers.

Dr Stephan Glander, global director – research and market development at Quadrant EPP, said: ‘Parts machined from Fluorosint HPV last longer than those made from many of the alternative filled PTFE materials on the market.

‘Fluorosint HPV can replace bronze, steel and powdered metal parts and deliver performance gains in wear life and system performance.

‘Typical applications include thrust washers, wear guides, seals and food processing and preparation equipment,’ he added.

Fluorosint MT-01 combines high temperature resistance with low deformation and low CLTE (coefficient of linear thermal expansion).

Glander said: ‘Engineers often need to balance compliance of PTFE, its ability to both deform and retain rigidity, with precise control, even at elevated temperatures.

‘Fluorosint MT-01 is perfectly suited to perform under these conditions,’ he added.

Fluorosint MT-01 was developed for high-temperature applications such as bearings, seals and wear surfaces where higher loads are present.

The ultra-performance grade is ideal for ovens, dryers and linear positioning equipment exposed to elevated temperatures.

Quadrant offers these materials in a range of rods, sheets and tubular shapes for machining.

Design and manufacturing of finished parts is also available.

The Fluorosint range of enhanced PTFE materials was developed by Quadrant to meet the performance requirements that unfilled and low-tech filled polymers can not provide for high-performance bearing applications.

Fluorosint’s properties are the result of a proprietary process in which synthetically manufactured mica is chemically linked to PTFE.

Quadrant said this bonding results in properties not normally attainable in reinforced PTFE.

Quadrant Engineering Plastic Products

Quadrant Engineering Plastic Products (QEPP) is the world’s leading manufacturer of semi-finished products made from general engineering and high-performance plastics. Quadrant also designs, develops and produces finished parts and solutions for a broad variety of applications in many different industries globally. Its product range extends from polyamide (PA), polyacetal (POM) and ultra high molecular weight polyethylene (UHMW-PE) to high-performance materials such as fluoroplastics and polybenzimidazole (PBI), which features temperature resistance to over 425C (800F) while maintaining total dimensional stability. The semi-finished products are machined or thermoformed and used in a variety of industries ranging from electronics through packaging machinery to chemical processing for applications where properties such as non-stick characteristics, abrasion resistance, dimensional stability, chemical and acid resistance or purity are extremely important.

Quadrant’s global teams of product development and applications engineers provide their customers with comprehensive advisory services. The best individual solution is sought for every customer requirement – from the choice of suitable material to optimum design of the finished product and machining of the most sophisticated materialsin state-of-the-art Technology Centres. Quadrant maintains a marketing and sales organization which is capable of pursuing new developments rapidly and efficiently worldwide.
