product safety and quality assurance — announcing the first X-ray
detectable UHMW-PE available in the market.
Repeated handling, cleaning and normal wear and tear of plastic
component parts on food, beverage and pharmaceutical processing
machinery increases the risk of a fragment breaking off and contaminating
the product during processing.
The need for traceable plastics, especially machined parts for filling, sorting
and packaging machinery is critical due to strict FDA regulations regarding
foreign materials and contaminants. Since we introduced our line of Metal
Detectable engineering plastics (Polystone M MDT (UHMW-PE) and
Sustarin C MDT (Acetal)) more than two years ago, these unique products
continue be an effective solution for plastic parts used in open product zone
applications.

![Probe Needles]( "Probe Needles")
Probe Needles
Probe Needles - Probe Punch Needles for Probe Card - Probe Testing - Locations in USA, Singapore, Taiwan
The wafer probe card is typically comprised of a printed circuit board with a set of precision-assembled probe needles. The probe needles are the tiny pins with sharp tips that contact the bond pads, or the signal terminals, on the IC chip during the testing. The probe needles are usually made of high-performance metals like tungsten with very good electrical conductivity and strong mechanical properties. The spacing between adjacent probe needles can be as tight as 20-30 microns, less than half the width of a human hair which is around 80 microns. There can be as many as a few thousand probe needles in the space of a few square centimeters on a probe card. Hence, the manufacturing of probe cards is one that requires tremendous technical expertise, R&D and intellectual property.
Probe cards, are considered 'consumables' as they have to be replaced or refurbished after a finite period. The usable life of a probe is determined by the number of 'touch downs' which is the number of times the needles of the probe card comes into contact with the chips on the wafer. Typically, probe cards last between a few hundred thousand to as many as a million touch downs.
Probe Needles are available from Professional Plastics is a full range of materials and sizes. These needles are produced to the highest quality available in the marketplace. Needles are produced using a special, proprietary machining technique used to grind needles of superior accuracy and consistency. This machine grinding creates smooth, straight surfaces (unlike chemical etching which can result in pits and concave/convex surfaces). Materials include Tungsten Carbide (WC), Beryllium Copper (BeCu), or Tool Steel.

![PTFE Fillers & Addititives - Overview]( "PTFE Fillers & Addititives - Overview")
PTFE Fillers & Addititives - Overview
PTFE fillers don't act like elastomer fillers, which become chemically bonded to the elastomer. With polytetrafluoroethylene, the high shear modulus fillers are encapsulated and bound by the low shear modulus PTFE.
Here's an overview of PTFE fillers:
- Glass is the most common filler for PTFE. Widely used in hydraulic piston rings, glass gives good wear resistance, low creep, and good compressive strength. Glass also has excellent chemical compatibility. The major disadvantage is that glass-filled PTFE compounds are abrasive to mating surfaces, especially in rotary applications.
- Molybdenum disulfide (MoS2) improves wear resistance and further lowers the coefficient of friction. "Moly" is typically combined with other fillers (such as glass and bronze).
- Carbon (powder or fiber) imparts excellent compression (low deformation under load) and wear resistance, good thermal conductivity (heat dissipation), and low permeability. Carbon-filled PTFE compounds are not as abrasive as glass-filled compounds, but they are still more abrasive than polymer-filled compounds. Carbon-filled compounds have excellent wear and friction properties when combined with graphite. Carbon fiber lends better creep resistance than carbon powder, but fiber is more expensive.
- Graphite is a crystal modification of high purity carbon. Its flaky structure imparts excellent lubricity and decreased wear. Graphite is often combined with other fillers (especially carbon and glass).
- Bronze (a copper-tin alloy) lends excellent wear resistance and thermal conductivity. Bronze-filled materials have higher friction than other filled PTFE compounds, but that can be improved by adding moly or graphite. Bearing and piston ring applications often use compounds containing 55% bronze — 5% moly. Bronze-filled compounds have poorer chemical resistance than other PTFE compounds.
- Stainless steel supplies high wear resistance and load bearing capability, along with better chemical resistance than bronze-filled PTFE. Stainless steel is especially good in steam service.
- Wollastonite (calcium silicate) is a mineral filler giving properties similar to glass (minus the abrasiveness). The FDA has approved it for food service.
- PPS (polyphenylene sulfide, trade name Ryton®) was the first polymeric material used to improve PTFE's wear and abrasion properties. PPS-filled compounds also exhibit excellent deformation and extrusion resistance, making them good for use in back-up rings.
- Ekonol® is a thermally stable aromatic polyester. When blended with PTFE, it produces a composite material with excellent high temperature and wear resistance. Ekonol® will not wear mating metal surfaces, making it good for rotary applications. Ekonol®-filled materials are also good for food service.
- Polyimide is another polymeric filler offering superior wear and abrasion resistance. Polyimide-filled PTFE compounds have about the lowest friction properties of all filled PTFE materials, so they provide great performance in non-lubricated (dry) applications. They will not abrade mating surfaces (even soft materials such as brass, stainless steel, aluminum, and plastic). Polyimide is one of the most expensive PTFE fillers, however.
Other fillers include calcium fluoride (CaF2), which is specifically used in hydrofluoric acid (HF) service, and alumina (Al2O3), which can improve the mechanical properties of compounds destined for high voltage applications. Alumina-filled compounds are very abrasive.

![PTFE Shrink Tubing (2:1 & 4:1)]( "PTFE Shrink Tubing (2:1 & 4:1)")
PTFE Shrink Tubing (2:1 & 4:1)
PTFE heat shrink tubing (PTFE) is available in 2:1 and 4:1 shrink ratios, and is widely used in military applications (MIL-I-23053/12) because of its high continuous use temperature (250°C), and outstanding chemical resistance.
- PTFE heat shrink tubing is the most difficult of the three fluoropolymer materials to shrink due to its extremely high shrinking temperature (325-340°C). You can use a heat gun or welding torch to shrink PTFE, but these methods have a tendency to cause the material to overheat in small areas, while under-heating other areas, causing uneven shrinking and potential burning of the material. The most reliable method for shrinking PTFE Teflon is the use of a controlled temperature oven; however this is impractical with large harnesses or temperature sensitive components.
- PTFE heat shrink tubing is available in a 2:1 shrink ratio and 4:1. The 2:1 is available in up to four different wall thicknesses. Please note: when ordering our 2:1 PTFE Heat shrink, ORDER AS SIZE AFTER SHRINKING.
