We're proud to announce 4 new engineering plastics available for ordering immediately on the Big Blue online quoting and ordering system.
Here's a quick rundown of the new offerings:
- Polypropylene: A moderately tough, durable plastic. It has the unique characteristic of not fatiguing when repeatedly bent back and forth, so it can be used to make a hinge. The edges get a little bit of melted plastic reformed on them when cut with the laser, but other than that, it cuts cleanly.
- ABS (Acrylonitrile Butadiene Styrene): A stiff, strong plastic with good surface hardness. It is suitable for structural applications where a plastic with good dimensional stability is needed for non-moving parts. Laser cutting will leave ABS plastic with a slightly charred edge; we can optionally remove the charring or give you guidance on how to do it yourself.
- UHMW-PE (Ultra-High Molecular Weight Polyethylene): A plastic with outstanding impact resistance and good chemical resistance, and excellent lubricity. This material is similar to the High-Density Polyethylene used in kitchen cutting boards, where it is used because it can take a lot of abuse and still clean up easily. Its high lubricity means that it makes a good guide for roller chains or conveyor belts. When laser cut, it also leaves a slightly melted looking edge, much like polypropylene.
- White Acetal: this is like our black acetal, but in a different color. Acetal's high strength and excellent wear characteristics make it an ideal choice when you need a plastic for things like bearings, gears, and slides.
