 Products

  • Duratron® PAI
    Product Overview ■Maintains strength and stiffness to 500°F (260°C) ■Minimal expansion rate to 500°F (260°C) ■Excellent wear resistance in bearing grades ■Able to endure harsh thermal, chemical and stress conditions ...

  • With its versatile performance capabilities and proven use in a broad range of applications, Duratron polyamide-imide (PAI) shapes are offered in extruded, injection molded, and compression molded grades.

    Duratron PAI is the highest performing, melt processable plastic. It has superior resistance to elevated temperatures. It is capable of performing under severe stress conditions at continuous temperatures to 500°F (260°C). Parts machined from Duratron stock shapes provide greater compressive strength and higher impact resistance than most advanced engineering plastics (See Figure 22).

    Duratron PAI's extremely low coefficient of linear thermal expansion and high creep resistance deliver excellent dimensional stability over its entire service range (see Figure 23). Duratron PAI is an amorphous material with a Tg (glass transition temperature) of 537°F (280°C). Duratron PAI stock shapes are post-cured using procedures developed jointly by BP Amoco and Quadrant. This eliminates the need for additional curing by the end user in most situations. A post-curing cycle is sometimes recommended for components fabricated from extruded shapes where optimization of chemical resistance and/or wear performance is required.

    For large shapes or custom geometries like tubular bar, compression molded Duratron PAI shapes offer designers the greatest economy and flexibility. Another benefit of selecting a compression molded grade is that resins are cured, or "imidized" prior to molding which eliminates the need to post-cure shapes or parts fabricated from compression molded shapes.

    Popular extrusion and injection molding grades of Duratron PAI are offered as compression molded shapes. Typically, you can identify a compression molded grade as having a second digit of "5" in the product name.

  • Ertalyte® PET-P
    Product Overview ■Good for both wet and dry environments ■High strength and rigidity -- ideal for close tolerance parts ■Excellent stain resistance ■Good wear resistance and excellent dimensional stability ■Better resistance to acids than nylon or acetal ...

  • Ertalyte® PET-P

    Ertalyte® is an unreinforced, semi-crystalline thermoplastic polyester based on polyethylene terephthalate (PET-P). It is manufactured from proprietary resin grades made by Quadrant. Only Quadrant can offer Ertalyte®. It is characterized as having the best dimensional stability coupled with excellent wear resistance, a low coefficient of friction, high strength, and resistance to moderately acidic solutions. Ertalyte®'s properties make it especially suitable for the manufacture of precision mechanical parts which are capable of sustaining high loads and enduring wear conditions. Ertalyte®'s continuous service temperature is 210°F (100°C) and its melting point is almost 150°F higher than acetals. It retains significantly more of its original strength up to 180°F (85°C) than nylon or acetal (See Figure 9).

    In addition, Ertalyte® PET-P offers good chemical and abrasion resistance. Its low moisture absorption enables mechanical and electrical properties to remain virtually unaffected by moisture (See Figure 11). Ertalyte® PET-P can be machined to precise detail on standard metal working equipment.

    Ertalyte® is available as a "Food Grade".

    Ertalyte is FDA compliant in natural color and on request also in black. Natural colored Ertalyte® is also 3A-Dairy compliant. The material is an excellent candidate for parts used in the food processing and equipment industries.

  • Techtron® PPS
    Product Overview ■Excellent chemical resistance ■Essentially zero moisture absorption ■Machines to tight tolerances ■Excellent alternative to PEEK at lower temperatures ...

  • PPS (polyphenylene sulfide) products offer the broadest resistance to chemicals of any advanced engineering plastic. They have no known solvents below 392°F (200°C) and offer inertness to steam, strong bases, fuels and acids. Minimal moisture absorption (see Figure 21) and a very low coefficient of linear thermal expansion, combined with Quadrant's proprietary stress relieving processes, make these PPS products ideally suited for precise tolerance machined components. In addition, PPS products exhibit excellent electrical characteristics and are inherently flame retardant.

  • Acetals
    Product Overview ■Low moisture absorption ■High strength, stiffness ■Easy to machine ■No centerline porosity in Acetron® GP ■Many formulation options: Copolymer, Homopolymer, PTFE filled, and Internally lubricated/enhanced wear grade ...

  • Acetal provides high strength and stiffness coupled with enhanced dimensional stability and ease of machining. As a semi-crystalline material, acetal is also characterized by a low coefficient of friction and good wear properties -- especially in wet environments.

    Because acetal absorbs minimal amounts of moisture, its physical properties remain constant in a variety of environments. Low moisture absorption results in excellent dimensional stability for close-tolerance machined parts. In high moisture or submerged applications, acetal bearings outperform nylon 4 to 1. Acetal is ideally suited for close tolerance mechanical parts and electrical insulators which require strength and stiffness. It also offers resistance to a wide range of chemicals including many solvents.

    Quadrant offers both homopolymer and copolymer grades of acetal including enhanced bearing grade materials. Acetron® GP acetal is porosity-free and offered as our standard general purpose grade. For slightly higher mechanical properties, we offer a broad size range of the homopolymer acetal (Delrin®) products. For improved frictional properties PTFE-enhanced Delrin AF products are available.

  • Ketron® PEEK
    Product Overview ■Excellent chemical resistance ■Very low moisture absorption ■Inherently good wear and abrasion resistance ■Unaffected by continuous exposure to hot water or steam ...

  • Ketron® PEEK grades offer chemical and hydrolysis resistance similar to PPS, but can operate at higher temperatures. PEEK 1000 offers steam and wear resistance, while carbon-reinforced PEEK provides excellent wear capabilities. Our latest grade, PEEK HPV, offers outstanding bearing performance. PEEK can be used continuously to 480°F (250°C) and in hot water or steam without permanent loss in physical properties. For hostile environments, PEEK is a high strength alternative to fluoropolymers. PEEK carries a V-O flammability rating and exhibits very low smoke and toxic gas emission when exposed to flame.

  • Duratron® PEI
    Product Overview ■High strength and performs in continuous use to 340°F (170°C) ■High dielectric strength ■UL 94-V-0 rated with low smoke output ■Available in glass-reinforced grades ...

  • Product Details

BEWARE - Special Warning Notice about ExpoGuide and FAIRGuide

With the ongoing solicitations, SEMI would like to continue to alert you with questionable professional practices perpetrated against exhibitors by FairGuide.com (Austria) and Expo Guide (Mexico), Event Fair - The Exhibitors' Guide with their misleading directory services. There may be others that we are not aware of and are hence not named here. 

These companies provide legitimate exhibition guides aimed at exhibitors across the globe offering online listing services. They use a form which resembles and organizer's free catalogue listing service, inviting exhibitors to complete the form for an entry in an on-line directory. Unsuspecting exhibitors who sign and return the form are then contracted into a three-year, non-retractable agreement, which could cost the exhibitor a significant amount of money, with very limited foreseeable benefits. The details are often available on the form itself, but are often too small and insignificant to be noticed. It is always wise to really the small print before signing a contract, and if the information is impossible to read then the contract should not be signed. These publications have no connection with SEMI or any of our events, and it is important that all companies are made aware of this. 

Should you receive any communication from the Expo-Guide and Fairguide.com or related company, please IGNORE THEM COMPLETELY and DO NOT COMMUNICATE WITH THEM IN ANY WAY.
