How much does parylene cost?

Everyone loves the barrier properties of parylene.  The resistance to solvents and moisture, incredible dielectric strength, and the completely uniform coverage are enough to make any engineer squeal with delight.  The question that immediately follows is, “How much does parylene cost?” 

There are a couple different factors that go into decided parylene cost.  One of these factors is the material cost.  Parylene dimer can be anywhere from $100 to $10,000+ per pound depending on the type and quality.  Other raw materials, such as the cleaning materials and adhesion promotion mediums, also factor into the materials costs for parylene.6228655557 65dbf31113

Another large factor that goes into parylene cost is the size and quantity of the objects to be parylene coated.  The objects get placed into a chamber during the parylene process for coating.  Since the machine has fixed costs to operate, by maximizing the number of objects in the chamber will spread these fixed costs out, lowering the price per unit drastically.

By far, the largest factor in determining how much parylene will cost you is the amount of human intervention that is required.  Human intervention is the amount of time that will be required for our operators to properly apply adhesion promotion, mask, de-mask, and inspect the products prior to completion.  Obviously with labor rates being so high, greater amounts of direct labor required will result in much higher prices.  

As you can see, many different factors go into deciding how much parylene costs.  If the product is small and requires no masking, the price per could be very cheap, even less than a penny.  If the product demands all of the chamber space and takes eight hours to mask, then expect a very hefty bill when your product returns.
