Most grades comply with FDA and EU food contact regulations (2002/72 EC), and standard Hostaform products have successfully passed drinking water testing at WRAS, KTW and NSF. MT grades, with an active Drug Master File (No. 11559), comply with USP Class VI guidelines. All Hostaform products are also available in a wide array of colors that do not contain heavy metals.

CUTTING-EDGE COPOLYMER FOR QUIET, LONG-LASTING MECHANICAL PARTS

Developed with mechanical longevity and efficiency in mind, Hostaform® SlideX™ POM is an acetal copolymer that significantly reduces noise, wear or friction in the sliding motion of critical parts.

With a high mechanical property profile, Hostaform® SlideX™ POM is ideal for countless applications including, bearings, gear shift systems, stabilizer joints, roller shutter devices, and furniture slide systems. When compared to alternative materials, Hostaform® SlideX™ POM offers a significantly lower coefficient of friction without compromising high mechanical performance.

External lubricants, such as oil and grease, are not necessary. Hostaform® SlideX™ POM eliminates potential for poor lubrication, a root cause for part failure. The intrinsic low-friction properties allow for a smoother, more energy-efficient operation of machines. The inherent ability to resist wear, allows for outstanding, predicable, part performance over the life of the product.

When developing components and machines that exhibit low friction and wear, Hostaform® SlideX™ POM is the optimum choice. With more than 50 years of technical and application expertise, Celanese polymer experts work side-by-side with designers and engineers globally, to understand the tribological requirements of each application. We have developed a complete portfolio of Hostaform® SlideX™ POM grades perfectly suited for extending the life of critical, sliding, mechanical parts.

Hostaform® SlideX™ POM Benefits
  • Friction and wear modified.
  • Improved friction and wear performance versus POM, PET, PP and Steel etc.
  • Possible to be used without external lubricants
  • Noise-Free during sliding friction
  • Non-migrating tribo-additive
  • FDA approved, medical technology products possible
  • Mechanical performance comparable to Standard Hostaform C9021

RESISTANCE TO WEAR, FATIGUE, CREEP, MOISTURE, SOLVENTS AND ALKALIS

Product Properties
  • Wear, fatigue/creep resistance to -40°C

  • Excellent toughness/rigidity with moisture, solvent and alkali resistance

Application

Automotive, gear, pen, gas caps as well as consumer and industrial segments

  • Fortron

Fortron® polyphenylene sulphide (PPS) is a high-temperature semicrystalline polymer that provides high thermal stability, very high chemical resistance, stiffness, strength and creep resistance.

Product Properties

By adding glass fibers and glass fiber/mineral mixtures to standard Fortron PPS, it allows:

  • service temperatures up to 240°C
  • very good resistance to chemicals and solvents
  • inherent flame resistant (UL 94 V-0, some grades 5VA)
  • very low moisture absorption
  • suitable for lead-free soldering
  • excellent creep resistance even at elevated temperatures

The Fortron PPS chemical structure provides excellent chemical and thermal resistance. Insoluble in all known solvents below 200°C (392°F), it has very good stability in both typical and alternative automotive fuels.

Grades
  • Glass-filled grades
  • Mineral-glass grades
  • Low-wear grades
  • Blow-molding grades
  • Medical technology (MT®)
Processing
  • Injection molding
  • Extrusion (film, fiber, sheet, shapes)
  • Blow molding

In addition, Fortron PPS can be extruded with meltblown and spunbond technologies for melt spun nonwovens. Unfilled, high viscosity Fortron PPS is also suitable for extrusion and compression molding to produce sheets, rods and other stock shapes commonly used for prototyping.

It has broad automotive, drinking water, food contact and aerospace approvals.

  • Vectra / Zenite
