Plastisol, Nylon Powder & Vinyl (PVC) Powder

At Piper Plastics Corp., we process Polyvinyl Chloride and Nylon using different methods.
By far, the material that we process the most is Plastisol. Plastisol is a thermoplastic liquid at room temperature and is primarily composed of PVC suspension resin and plasticizer. When processed correctly using heat, the plasticizer, which makes the vinyl flexible, gets locked into the Vinyl molecules and the cooled part becomes a solid. Additional ingredients can be added to the formulations to add color, add antimicrobials, add texture, and impart various other characteristic to the finished products. Plastisol is used in all sorts of products, from plier handles to nasal cannula, bottle openers and heart catheters.
Another form of PVC that Piper processes is fluidized bed PVC powder. This is the same material as plastisol, however instead of being a liquid initially, it’s a fine powder. Utilizing a fluid bed, which blows air up through the powder, we can dip metal parts and create beautiful and colorful coatings. Familiar products that have been dipped using PVC powder in fluid bed include point-of-purchase displays, bagel baskets, military items and wristwatch display cuffs.
Finally, we also process Nylon powder at Piper. Utilizing the same fluid process as the PVC powder, we are able to apply Nylon to our customer’s products. Nylon is a thermoplastic that is much harder than and has a lower coefficient of friction than PVC.
Unfortunately, Nylon cost more than PVC, however there are times when it’s worth it because the physical properties of Nylon are needed for a particular application. A great example of a fluid bed nylon product is the basket for the blood pressure cuff you find in your doctor’s office.
If you’d like to learn more about material we process, please don’t hesitate to give us a call.
We’re Piper Plastics, and we’re the Big Dippers.

Hola soy de argentina, trabajo hace años con plastisol, siempre lo cure por medio de hornos. Me preguntó si me podrías dar información del plastisol hirviendo que se ve en el vídeo ?

In your video you state that color can be added to the plastisol, but don't address that issue any further. Do you have another video that shows how to change colors of the material. Furthermore, what scale do you use to know how much pigmentation to add to get the color you want? Thank you for your time!

The "rule of thumb" is to use as little pigment as necessary to achieve the desired result. Most plastisols will produce clear or "natural" parts without any additional pigment, even though it may look white in its liquid state.
