Polyimide - The Ultimate High-Performance Thermoplastic Material

Thermosetting Polyimides (PI) are known for thermal stability, good chemical resistance & excellent mechanical properties. They exhibit very low creep & high tensile strength. These properties are maintained during continuous use to temperatures of 450°F (232°C) and for short excursions, as high as 900°F (482°C).   Professional Plastics offers the widest range of polyimide materials in the industry from Meldin® Shapes, Vespel® Shapes, Kapton® Film, Kaptrex® Film, Cirlex® Laminate, Kaptolam® laminate, Solimide® foam,and Protomid® microbore tubing.

Molded polyimide parts & laminates have very good heat resistance. Normal operating temperatures for such parts and laminates range from cryogenic to those exceeding 500°F (260°C). Polyimides are also inherently resistant to flame combustion and do not usually need to be mixed with flame retardants. Most carry a UL rating of VTM-0.

Polyimide laminates have a flexural strength half life at 480°F (249°C) of 400 hours. Typical polyimide parts are not affected by commonly used solvents & oils — including hydrocarbons, esters, ethers, alcohols and freons. They also resist weak acids but are not recommended for use in environments that contain alkalis or inorganic acids.

Polyimide parts and shapes such as Meldin®, Vespel® are produced via Isostatic Molding, Compression Molding or Direct-Forming.

Grades of Meldin Polyimide:
MELDIN® 7001, Unfilled Grade
A thermosetting polyimide, MELDIN® 7001 is our unfilled base resin. This grade offers the maximum mechanical properties and high chemical resistance. The MELDIN® 7001 grade is ideal for electrical and thermal insulating applications. More ductile than ceramics, and lighter weight than metals, MELDIN® 7001 is a popular choice for structural parts in aerospace and other applications where metal replacement is desirable.

MELDIN® 7021, 15% by Weight Graphite Filler
Our self-lubricating grade, MELDIN® 7021, has 15% by weight graphite fillers, encapsulated by the base polyimide resin. With its low coefficient of friction and high heat resistance, MELDIN® 7021 provides our customers the best all-around choice for high temperature bearings, seals, and other low-wear applications.

MELDIN® 7211 - 15% Graphite + 10% PTFE Fillers by Weight
MELDIN® 7211 is 15% by weight graphite and 10% by weight PTFE fillers. It has the lowest coefficient of friction of all the MELDIN® 7000 grades. However, above 300°F, we typically use MELDIN® 7021, which has a very similar coefficient of friction to 7211 at temperatures above 300°F, and the wear factor of 7021 is lower than 7211 at temperatures above 300°F.

MELDIN® 7022 - 40% by weight graphite filler
MELDIN® 7022 is 40% by weight graphite filler. It is similar to the 7021 for wear and friction, but it has the best overall dimensional stability (thermally), and the 7022 has the lowest coefficient of thermal expansion – due to the relatively high graphite filler content.

MELDIN® 7003 - 15% molybdenum disulfide lubricating filler
Meldin® 7003 includes 15% molybdenum disulfide lubricating filler for wear applications that operate in a vacuum or in very dry conditions where graphite actually becomes abrasive. Typical applications of Meldin 7003 include seals, bushings, bearings, gears, and other wear surfaces in outer space, ultra-high vacuum or dry gas applications.

Meldin 7000 meets the following specifications :

Mil-P-46198 Military Specification (now obsoleted)

ASTM D6456-99 Standard Specification

SAE AMS 3644G Aerospace Material Specification

CPW411 Rev. H Pratt & Whitney Specification

MCS 5016 Honeywell Specification

UL V0-5VA flammability rating

Polystone® M XDT - New X-Ray Detectable UHMW-PE Shapes

Polystone® M XDT (X-Ray Detectable UHMW-PE) is available from Professional Plastics, Inc.
Röchling Engineering Plastics continues to set trends and provide solutions in the food processing and pharmaceutical industries when it comes to 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.

However moving forward, we quickly realized a demand for X-ray detectable plastic parts for today's high speed machinery as processors turn to X-ray inspection equipment especially for post-package inspection. Working together with one of the world's largest food processors and a leading manufacturer of X-ray inspection systems, our Polystone M XDT has proven to be detected with a particle size as small as a 3mm cube. Running at speeds as fast as 250 feet-per-minute, this product can be detected and automatically sorted to a product hold area for further inspection. It works effectively with various types of packaging including metal cans, plastic and composite containers and glass jars.

Applications: - Scraper blades - Mixer Components - Baffles - Filler plates - Wear plates - Pillow blocks - Pocket fillers - Volumetric fillers - Cups & Sleeves - Piston fillers - Hopper guides - Dividers

Polystone® M XDT can be detected as small as a 3mm cube.

Polystone® M XDT - the industry's first X-ray detectable UHMW-PE

Note:  It is the responsibility of the user to test and approve the detection of this product due to variations in x-ray detection systems and required sensitivity settings.

Polystone® M XDT is available in both sheets, rods and fabricated parts to your specifications.
Rods: .500" to 6" diameter (12.7mm to 152mm)
Sheets: 3/8" to 4" thick (9.52mm to 101mm)

8 Everyday Uses For Teflon

Considering the fact that plastic products seem to find their way into several aspects of one's everyday life, it should come as no surprise that Teflon, created by DuPont research scientist Dr. Roy Plunkeet in 1938, seems to appear time and time again on the list of essential ingredients to many products. Take for example the list below:

8 Everyday Uses For Teflon

Cooking:  non-stick pots and pans

Beauty Products: nail polish remover and curling and flat irons

Automotive: windshield wiper blades

Apparel and Home: fabric and upholstery protection

Manufacturing: machines and applications which require sliding actions or require bearings, sliding plates, gears, bushings, etc.

Medical: medical equipments and Teflon grafts and implants

Research: laboratory equipment like containers and tubing

Technology: Computer equipment and robotics
