Frequently Asked Questions
Can Polyketone easily replace today’s commonly used plastic materials?
Yes! Polyketone is a drop-in replacement for these materials because they are all semi-crystalline resins and exhibit a similar mold shrinkage during processing. So polyketone can be molded in existing tooling which enables a solution without having to purchase and build new molds (a big savings, too).
And with polyketone, you don’t need to retool the die to run a sample.
What common manufacturing headaches does polyketone solve?
Polyketone is what we call “processing friendly,” and it’s a clear winner compared to polyacetal. Unlike polyacetal, which produces formaldehyde gas—a hazardous material—polyketone doesn’t generate any fumes, odor or gas during processing.
Polyketone outshines nylon as well due to nylon’s tendency to absorb moisture and swell in humidity. This means if nylon is produced in one region of the world and sent to another region with a different humidity level, its shape and size will change.
Conversely, polyketone holds the same size and fit regardless of where it is produced and where it is sent. So for tight tolerance demanding applications, polyketone is the material of choice.
Is polyketone a cost-effective solution?
Absolutely. Polyketone wins hands-down when it comes to cost. Some manufacturers explore the use of high performance nylon (for example, PA11 and PA12) as an alternative material because of its lower moisture absorption than standard nylons. Polyketone competes effectively with PA11 and PA12 on moisture absorption and dimensional stability but clearly stands out with a much lower cost. Polyketone is 5x less expensive than PA11 and PA12 and 2x the heat resistance.
