Working in partnership with Quadrant Plastics, fwb stocks an extensive range of engineering plastics and provides a bespoke cut-to-size service.
Those ranges available off-the-shelf are described below. The various plastics are commonly kept in rods, tubes, sheets and blocks.
Because materials are stored in bulk and must be cut to order we cannot offer this product for sale online. Instead, to discuss your requirements visit the branch locations page for all our contact details.
Virgin reprocessed, coloured or modified ultra-high molecular weight polyethylene.
Tivar Eco Green
Ertalon and Nylatron
Polyamide materials which in general offer high high mechanical strength and rigidity, high mechancial damping abilities, low surface friction, good electrical insulation, good machinability and good resistance to high energy radiation (gamma and x-ray).
Nylon based materials can absorb water up to 7% when subjected to high humidity or are submerged. This may result in dimensional changes of up to 2% and will dilute materials mechanical properties.
Ertalon 6 PLA
Ertalon 66 SA
A range of materials based on polyetheretherketone resin. It's semi-crystalline structure exhibits a combination of high mechanical properties, temperature resistance and chemical resistance making it a popular plastics material. The material boasts high max allowable service temperatures in air of 250 Celsius continuously or up to 310 Celsius for brief perids. However stiffness decreases and thermal expansion rate increases above the materials' glass transition temperature of 150 Celsius. As such, close tolerance and bearing applications above the transition temperature must be carefully considered.
Ketron HPV PEEK
Copolymer acetal material. In general Nylon is considered better suited to abrasive wear situations but for dimensional stability and electrical insulation Ertacetal is a strong contender. Typical uses include small modulus gear wheels, cams, bearings & seals with small tolerances, valve seats and snapfit assemblies.
Fluorosint 500 PTFE
A material in which industrially produced mica is chemcially included into PTFE. This provides a material with an excellent combination of low friction properties and high dimensional stability, making it ideal for seats and seals.
It's coefficent of linear expansion is comparable to aluminium and is 1/5th that of virgin PTFE. It is also considerably harder, has improved wear characteristics and maintains low frictional properties.
