Custom Fabricated Mechanical and Engineering Plastics
Below are some of the more common plastic products we use to create custom fabricated mechanical and engineering plastic products for our customers:
UHMW: “Ultra high molecular weight” polyethylene. With its unique combination of properties, as well as its relatively low cost, UHMW is rapidly becoming the material of choice for many mechanical applications. It has been used as a replacement for steel as wear strip and channel liners for years in the lumber and plywood industries. In its natural form UHMW meets all criteria for food contact. This allows it to be used in all stages of food processing, from harvesting through to final packaging. Physical properties, such as low coefficient of friction, resistance to wear, resistance to impact and excellent machinability only add to its appeal.
Nylon: Whether in extruded or cast forms, nylon has long been a principle material in the plastics industry. Nylon resins accept a multitude of fillers, which allows for a variety of different formulations to better fit individual applications. From marine bearings to crane wear pads, cable & rope sheaves to bottling plant star wheels, gears in paper mills to lumber mill carriage wheels, the uses for nylon products are endless. Prime properties include impact resistance, load capacity, wear resistance, and its chemical resistance.
Acetal: Commonly referred to as “delrin”, this product has similar physical properties to nylon, with a few notable differences. Acetal materials are harder and slightly more brittle. This added stiffness makes it very machinable, and adds dimensional stability. Acetal also absorbs very little moisture; therefore it is an excellent material for high moisture environments. Acetal is available as both homopolymer and copolymer resins. Homopolymer product “delrin” is more susceptible to center porosity in larger parts.
Teflon (PTFE): Teflon is well known for it's high temperature resistance (500 F), slippery surface, electrical insulation, and it's high chemical resistance. Due to it's soft nature, Teflon is particularly well suited to seals, gaskets, packing rings, and other applications where mating parts will seat themselves to create a seal.
Ertalyte (PET-P): This is an un-reinforced polyester based material with exceptional dimensional stability, wear resistance, low frictional values, and great chemical resistance. With its low moisture absorption, ertalyte maintains it's mechanical and electrical properties even in very high moisture environments.
Composites: This material is a polyester fabric/polyester resin product offering unmatched bearing properties. Designed for high load, low to moderate speed bearing applications, it has exceptional dimensional stability under a wide range of conditions. Composites are filled with a variety of lubricant materials to match individual applications. With less that one third of one percent moisture absorption, these materials are ideal in water lubricated, or high moisture environments. Standard grades are stabile to 265 degrees F, with high temperature grades available to 400 degrees F.
Micarta: Also called phenolics, or high-pressure laminates. These products have been around for 50 years, and are still widely used as bearing materials, electrical insulators, mechanical stand-offs, and in many applications where strength and stiffness are required. Canvas or linen grades are the most widely used. However, glass and paper based grades are also common materials.
Dura-Scuf: Continuous length scuff board. Extruded in our plant using reprocessed UHMW. This ultraviolet stabilized, nearly indestructible 9/16” thick by 12” wide scuff board is used in truck trailers, rail cars and on docks. It also has been used in the wood products industry, and for farming, and irrigation. This is the material of choice when other materials fail under high impact and abrasion. It can be coiled in long lengths for shipping.
