Teflon is a trademark of the DuPont company. Teflon (PTFE), or Polytetrafluoroethylene, is a specialty material used in many applications due to its unique properties. There are some safety issues but overall it is a common and safe coating used for mechanical wear components, contacts, etc. A Teflon coating can greatly reduce surface friction. Teflon is a polymer which contains fluorine.

Teflon, Xylan and other similar materials are used in many medical and life science applications (including implantables) because they are FDA approved and can be placed on top of base materials which are not FDA approved. The following is a brief summary of some of the useful properties and applications for Teflon coatings.
Reduce friction
Reduce galling
Extend lifetime of:
Sliding parts
Bearings
Bushings
Gears
Side plates
PTFE and Xylan coated parts are bio-compatible which is useful for medical applications.
Virtually all industries find Teflon plated components useful.
Yes, it is commonplace. Customers may choose to provide material or allow INTA to provide the component.
INTA Technologies can plate small lots. We can easily accommodate your small order. The teflon coating usually happens off-campus at a trusted partner's facility.
Teflon plating lead times are longer than other types of plating lead times. Two weeks lead time is not uncommon for Teflon plating projects, sometimes it can be even longer depending on the complexity. For a new order, count on 2-4 weeks for a lead time. For repeat orders, lead times are usually shortened by 1-2 weeks.
INTA Technologies Corp. has been in business since 1978 offering top quality goods and services. INTA is ISO 9001:2008 certified and have rigorous inspection methods and processes. Training is a large part of our system as is inspection. All employees are fully trained and re-trained periodically. George Baltazar is our highly qualified Quality Manager who has worked in this industry for many years. Documentation and process control are very important to INTA. INTA has quarterly internal audits and annual external quality audits. We also have weekly NC/CAR meetings and use root cause analysis to analyze key data.
No, DFAR, ITAR and other similar clauses are strictly adhered to. INTA does quite a bit of work for Federal contracts and prime contractors and the staff at INTA has received training with regard to this important topic.
Pricing varies depending on the project. Most Teflon coating projects are worth at least several thousand dollars (not piece price but extended price). Teflon coating is not as common at INTA in comparison to other plating services but if you have a certain budget or target price please inform our staff when contacting INTA.
Almost any material can be plated with PTFE. Several materials are unacceptable to INTA Technologies due to RoHS compliance requirements including lead, cadmium and hexavalent chrome.
There is more work and materials involved in many Teflon coating applications which drives prices higher in comparison to Xylan or metal plating in some cases. If there is a large volume order the price can be very reasonable. For small orders, the price can be a bit higher than expected. Each project and component is unique, for a quote please contact sales@intatech.com
Teflon is not a specialty for INTA and it is only a small segment of the business. INTA Technologies Corp. derives most of its revenues from the following products and services:
Metallized ceramic products
CuW components
Machined components
Brazing service
Assembly service
Plating service
Metallizing service
No, INTA does not offer that service.
MIL-P-20689 is a common industry specification for plastisol dip. This is a plastic coating. INTA plates on plastic but does not deposit plastic on components.
