PBT

PBT

PBT (polybutylene terephthalate) is a strong and stiff engineering plastic with excellent machining characteristics, chemical resistance, and bearing and wear properties. It is often used for food processing machinery applications when low moisture absorption, resistance to staining, or resistance to cleaning chemicals is required. PBT is ideal for applications such as cams, bearings, gears, food pistons, wear strips, scraper blades, valve bodies and conveyor components.

Elastomer ( TPE, TPR, TPU & TPV Etc.)

Elastomer ( TPE, TPR, TPU & TPV Etc.)

Health care facilities use several varieties of elastomers at all levels. Elastomers are chosen for their outstanding sterility, low leaching level, and biocompatibility. 

Elastomer ( TPE, TPR, TPU & TPV Etc.)

As a polymer, elastomers fall into a group of pliable polymeric, or plastic, material that includes artificial and natural rubber. They are good for molding, insulating, can withstand deformation and are formed easily into an assortment of rubbery shapes that are then hardened. Their versatility and usefulness make the application of elastomers popular in a wide variety of everyday products, from skateboard wheels and the soles of sneakers, to gaskets and electronic cabling and wire insulation.

Properties

  • Physical Versatility – One of the most obvious advantages of elastomers is their custom molding in size, shape, flexibility, and color to customer specifications.
  • Short Production Times – Elastomers can be mixed, molded, and cured or vulcanized rapidly, which makes for short production times.
  • Good Insulator – Its closed cell properties make for effective insulation of electronic and electrical products in a variety of home and industrial applications.
  • Excellent Adherence – Elastomers can easily be installed next to various other materials, such as metal, hard plastic, or different kinds of rubber, with excellent adherence.

Some standard medical devices made from elastomers include:

Gloves

Latex in gloves is produced from natural rubber. These medical devices are common in the medical field. Besides, non-latex gloves are also made from elastomeric materials.

Implants and Prosthetics

These critical medical devices are made from medical-grade elastomers. The manufacturing process makes use of the material’s flexibility attributes to achieve the desired results. Essentially, implants require some level of flexibility for ultimate comfort.

Medical Tubing

These critical medical devices are made from medical-grade elastomers. The manufacturing process makes use of the material’s flexibility attributes to achieve the desired results. Essentially, implants require some level of flexibility for ultimate comfort.

Syringe Gaskets

Syringe gaskets benefit from elastomer compounds. Its applications can be found in syringe plunges, forming a leak-proof seal with the syringe barrel. The elasticity typically guarantees no backflow against the syringe’s sides, and the material doesn’t succumb easily to pressure when the plunger is pushed.

Oxygen Masks

Oxygen masks made from elastomers benefit from excellent elastic properties. These properties allow for a comfortable fit and gentle natural molding to facial curvature.

  • Good fatigue resistance.
  • High mechanical damping ability
  • Good sliding properties.
  • Excellent wear resistance
  • Good electrical insulating properties
  • Good resistance to high energy radiation (gamma & x-ray)
  • Good machinability.

KEY APPLICATIONS

  • Sleeve and slide bearings
  • Wear pads
  • Support and guide wheels
  • Seal rings
  • Cable sheaves
  • Hammer heads
  • Scrapers
  • Gear wheels
