are a diverse family of rubber-like materials that can be repeatedly melt processed. Additionally, LSR has a specific gravity that is 20% higher than TPEs (+/- 1.12 versus +/- 0.89), which means LSR will produce 20% fewer parts for every pound of material used. Bear in mind, thermoplastic properties of TPEs mean that chemical resistance is most likely to worsen as temperature is raised.

Modulus One common myth in the TPE industry is that the durometer (or hardness) of a material is directly related to its flexibility. Table 2 summarizes general shrinkage ranges for the various GLS product families. Table 2 summarizes general shrinkage ranges for the various GLS product families.

SMARTER MATERIALS™ High-Performance Thermoplastics Contents Table of Introduction Your Next Move Advantages Creative Color All In The Family Processing Options Critical Differences Measuring Thermal Performance Markets & Applications Just like elite athletes who surpass the limits of typical human accomplishment, high-performance thermoplastics surpass commodity and even engineering resins with their exceptional capabilities. To answer these, we will look at five different material families: • Polyaryletherketones (PAEK) • Polysulfones (PSU) • Liquid crystal polymers (LCP) • Polyetherimides (PEI) • Polyphenylene sulfides (PPS) Read on to discover the diverse and growing uses for these elite-level performers of the thermoplastic world. Following are top reasons why many manufacturers and designers choose high-performance thermoplastics: • High-temperature resistance • Chemical resistance • Flame/smoke/toxicity (FST) performance • Chemically inert PLUS, ALL THE BENEFITS OF PLASTIC In addition to their elite-level properties, high-performance thermoplastics deliver the typical advantages of polymers over other material types such as metal, glass and ceramic, including: • Light weight • Design freedom/part consolidation • Easy colorability • Efficient, high-volume processing • Elimination of secondary operations • Enhanced product experience for the end user - quieter environment - improved tactile feel - better usability ADVANTAGES Going Above and Beyond • Amorphous structure • High marks for toughness, chemical resistance, hydrolytic stability, resistance to boiling water, and extreme thermal capabilities • Best for: aerospace interiors, hot water fittings, and medical and dental devices that are subjected to repeated steam sterilization • Also used in food equipment exposed to temperature extremes, such as coffeemakers or freezer-to-microwave cookware Polyaryletherketones Polysulfones Liquid crystal polymers Polyetherimides Polyphenylene sulfides There are five major families of high-performance thermoplastics P O LY AR YL ET H ER K ET O N ES P O LY SU LF O N ES• Semi-crystalline structure • High marks for thermal stability, chemical resistance and mechanical properties over a wide temperature range • Better-than-average levels of combustion resistance and electrical performance • Some PAEK materials, like polyetheretherketone (PEEK), are also extremely tough and have excellent impact strength • Best for: aerospace, automotive, industrial and medical components • May be used to create stock shapes such as rods, bars, and tubes All in the Family P O LY P H EN YL EN E SU LF ID ES • Semi-crystalline structure • Excellent temperature resistance with continuous service temperatures up to 230°C • High marks for modulus and resistance to creep, corrosion, and chemicals • Above-average electrical properties • Best for: complex parts with extremely tight tolerances; often used as an alternative to metals and thermosets in automotive underhood parts, appliances, electronics, and industrial applications Polyaryletherketones Polysulfones Liquid crystal polymers Polyetherimides Polyphenylene sulfides There are five major families of high-performance thermoplastics P O LY ET H ER IM ID ES LI Q U ID C R YS TA L P O LY M ER S • Semi-crystalline structure • High degree of anisotropy: strength, stiffness and thermal expansion will be greater in one direction vs. the other • High marks for temperature, chemical and electrical resistance • Exceptional mechanical strength and high flow rates; often used to fill extremely long parts with thin walls • Best for: electronic connectors, sensors, bullet-resistant vests, jet engine enclosures, brake and transmission friction parts, and gaskets • Amorphous structure • High marks for thermal, mechanical, and chemical properties • Often selected for demanding applications requiring ultra-high mechanical strength combined with high temperature, corrosion and wear resistance • Impact resistance may be lower than that of PSUs and PAEKs • Best for: aerospace interiors, automotive lighting, medical devices, and electrical and fiber optic connectors All in the Family Source: https://www.craftechind.com/standard-and-custom-parts-in-high-performance-plastics/ TEMPERATURE AND MATERIAL TYPE The two broad classifications of high-performance thermoplastics—amorphous and semi-crystalline— have different temperature characteristics.
