High Performance Plastics

Continuous Fibre-Reinforced Thermoplastic Plates
For applications where the mechanical requirements are too high for unreinforced or short fibre-reinforced plastic stock shapes, continuous fibre— reinforced thermoplastic plates offer an excellent alternative. Thanks to the continuous fibre reinforcement, usually a woven fabric of glass or carbon fibres, they have mechanical properties otherwise achieved only by metallic materials. At the same time, they are significantly lighter than most metal-based alternatives. Through the use of thermoplastic matrix materials, the plates nevertheless have the same advantages as unreinforced plates made from thermoplastic materials: high impact strength, constant properties over a broad temperature range, chemical resistance and high elongation at break.

Plates made from continuous fibre-reinforced thermoplastics can be processed into finished parts of outstanding quality with minimal tolerances. Alongside water jet cutting, conventional processing methods are also suitable – assuming suitable facilities and processing parameters.

Ensinger has widened its portfolio of composite plates to include three new materials: TECATEC PPS CW50, TECATEC PEI GW50 and TECATEC PC CW50. TECATEC PPS CW50 black (PPS CFK – Polyphenylene sulfide, carbon fibre-reinforced) offers excellent high-temperature resistance, has very good chemical resistance and dimensional stability over a broad temperature and humidity range and its carbon fibre reinforcement increases stiffness and strength. Their TECATEC PEI GW50 natural (PEI GFK – Polyetherimide, glass fibre-reinforced) offers high continuous service temperature (170°C), good electrical insulation, is fire, smoke and toxicity retardant (FST) and its glass fibre reinforcement increases the mechanical properties while keeping costs down. And TECATEC PC CW50 black (PC CFK - Polycarbonate, carbon fibre-reinforced) offers outstanding appearance thanks to crystal-clear, transparent matrix, high impact toughness and its carbon fibre reinforcement increases stiffness and strength.

The new composite plates have densities between 1.5 and 1.8 g/cm@, giving them a similar specific weight to unreinforced or short fibre-reinforced plates. The reinforcing fibres increase their mechanical properties dramatically to a level similar to metal. Compared with unreinforced polymer plates, continuous fibre-reinforced plates achieve values that are 5 times higher for both tensile strength and Young’s modulus.

Continuous fibre-reinforced thermoplastics exhibit extremely low coefficients of thermal expansion (CTE) in a range around 5x10-6 K-1. This property is of great importance for applications in which the parts are subjected to temperature fluctuations over a broad range and where high precision is required.

The thermoplastic matrix gives the plates high impact toughness, with the value significantly higher than in plates with a thermoset matrix such as epoxy or phenolic resins. The high elongation at break of the thermoplastics ensures tough, non-brittle fracture behaviour. For some applications, the intrinsic vibration damping of the matrix can also be a relevant advantage.

Ensinger produces the thermoplastic composite plates to customer-specific requirements, with maximum dimensions of 525 x 625 mm. The manufacturer is also flexible when it comes to the plate thickness: in the range 0.5 to 95 mm, any thickness is possible.

High-Performance Engineering Plastics
Westlake Plastics is a leader in supplying innovative high-performance engineering plastics shapes for machined parts. For over 40 years, Pomalux®, Absylux®, Zelux® and Propylux® have set a standard for machine grade polymers in the machin - ing/fabrication industry. What differentiates Westlake Plastics from their competitors’ extruded sheet is their unique compression molding process. Compression molding provides bestin- class dimensional stability due to their proprietary isotropic stress relieving process. Compression molding provides an engineering plastic sheet that stays flat and resists warping during machining processes. Extruded plastic sheet does not machine the same as compression molded sheet. Extruded plastic sheet could warp or twist when machining material off one side of the sheet or machining large, pocketed areas… causing your machine shop customers higher scrap rates, lost machine time, additional raw material costs and big headaches for you because of complaints and returns.

You might expect to pay more for Westlake Plastics’ compression molded plastic sheet but improvements in their process have allowed them to offer their products at a more competitive price, providing their customers access to a premium machinegrade plastic sheet at extrusion-grade pricing.

Polyimide Shapes & Liquid
R. Blaine Industries (RBI) recently announced the expanded availability of its VTEC™ polyimide stock shapes, parts and liquid materials. Small diameter rod has been added, with sizes as small as .060” diameter now available. Incremental diameters are also available to reduce the need to turn down from larger diameters. Other additions to the line include 300mm square sheet stock, and many OD/ID tube and bushing stock sizes.

VTEC creates new revenue opportunities, and offers distributors and fabricators a quality alternative to Vespel®, Meldin®, Plavis®, and other polyimides (PI). RBI's unique new VTEC economy grade (EG) materials bring down the high cost of traditional polyimides while providing unparalleled reliability comparable to other high performance materials.

Hybrid VTEC polymer materials are available with many fillers and modifications including carbon, graphite, glass, PTFE, fibers, and minerals to exactly match application requirements to replace metals, and upgrade many other polymers which are underperforming.

VTEC is a virtually indestructible polymer that overcomes many of the limitations of traditional high performance plastic materials. VTEC is not sensitive to moisture and steam, which makes it ideal for oil patch applications. Also, VTEC EG does not have a low Tg problem in high temperature applications. And, VTEC EG is ideal for any type of bearing and wear application to 500°F continuous.

VTEC Polyimide is also available in liquid form for applications where a polyimide coating or film is desired. It is typically applied and then thermal cured into a thin film or coating layer. Applications include cast films (including ESD); thin wall tubing; glass coating (to reduce breakage); metal coating (to create a high temp wear surface or to make metal non-conductive); semiconductor and microelectronic stress buffers or passivation layers; high temp adhesives; optical fiber and capillary coatings; R&D projects; wire enamels, etc. VTEC Polyimide liquid adds a new dimension to a distributors’ overall offering of advanced polymers.

RBI's VTEC line of polyimide and hybrid materials also includes directformed parts and machined parts, in addition to stock shapes (sheet, rod, tube). RBI also produces near-net custom shapes that save machining time as well as material cost. Medical implant grades of VTEC in liquid and solid from are also available and solving next generation application challenges.
