Press Release Summary = Metal Detectable Plastic for Engineering Applications
Press Release Body = E-Components & Chains Limited of Pocklington (UK) are pleased to announce the launch of their very own Detectamet/Detecta-thane Metal Detectable Detectamet/Detecta-thane" is a metal detectable general purpose compound having good mechanical properties. Features include good heat stability inside temperature range, high impact resistance, excellent abrasion resistance, tough & durable, supplied in specific colour; Blue. Hardness Detectamet/Detecta-thane is supplied in a range of hardnesses from 25° Shore A which is softer than a pencil rubber or an elastic band to 84° Shore D which is harder than a golf ball.The table below gives some guidance as to these hardness ranges. Compression When load is applied to a Detectamet/Detecta-thane it deflects but unrestrained surfaces bulge in sympathy. This is because Detectamet/Detecta-thane is incompressible and acts like a fluid capable of changing its shape to the limit of its strength under load. Strictly speaking this is not compression but nevertheless it is the term used in elastomer technology. Detectamet/Detecta-thane has a higher load bearing capacity than that of more conventional elastomers for the same hardness. This characteristic permits greater design choices and usually allows the use of smaller components. ECC/Detectamet can offer guidance on polymer selection and provide indicative load and deflection figures for most compression applications. Tension Tensile strength and associated elongation are usually measured as part of material and process control regimes. It is rare that elastomers are used in tension and then only at a small fractlon of thelr ultimate strength. Even so Detectamet/Detecta-thane has much higher tensile strengths than conventional elastomers. Resilience While resilience is generally a function of hardness in conventional elastomers, this is not true of Detectamet/Detecta-thane. Detectamet/Detecta-thane can be formulated to give a wide range of resilience values. An added benefit is that the resilience changes very little between 10°C and 100°C giving more consistent performance in a variable environment. Abrasion When compared to rubber, plastics and metals Detectamet/Detecta-thane offers outstanding resistance to wear giving many times the life span of these conventional materials. Detectamet/Detecta-thane can be tailored to suit sliding and impingement abrasion and has a well deserved reputation for its durability. Temperature Detectamet/Detecta-thane will provide excellent service in cold stores and Arctic conditions. Physical properties change little down to -15°C, and while further reductions in temperature result in a gradual stiffening, Detectamet/Detecta-thane is still quite serviceable at -70°C. At higher temperatures Detectamet/Detecta-thane will provide good service up to 90°C and is suitable for intermittent use at 120°C. Beyond these temperatures, specially formulated materials are needed. Water Resistance Selected grades of Detectamet/Detecta-thanes are suitable for use in water at up to 50°C. Water absorption is very low and volume swell is negligible. This means that precise components can be used safely in water without fear of size changes affecting performance. High humidity has little effect on Detectamet/Detecta-thanes and a secondary benefit is that these elastomers do not support fungus growth and are generally resistant to such attack. This makes Detectamet/Detecta-thanes mouldings particularly suitable for tropical environments. Mechanical Properties At low hardnesses all elastomers, Detectamet/Detecta-thane included, merely bend under impact. As hardness rises elastomers and plastics demonstrate a tendency to brittleness and crack under impact. Detectamet/Detecta-thane has significantly better impact resistance than any material of comparable hardness. Detectamet/Detecta-thane will resist cracking under repeated flexing. Selection of the appropriate grade will allow extremely high life spans, with tests proving that in excess of 1,000,000 cycles is common place. Detectamet/Detectathane will also show excellent resistance to cut propagation and can be used in very thin sections because of its exceptional strength and toughness. Friction Detectamet/Detecta-thane resembles most other elastomers in that friction decreases as hardness rises. The coefficient of friction against non-Iubricated surfaces ranges from 0.2 (hard polymers) to 0.6 (soft polymers). Machineability It is possible to machine most grades of Detctamet/Detecta-thane. The harder grades can be processed on most conventional machine tools, while softer compounds need to be ground or cut with very sharp tools. Electrical Properties Detectamet/Detecta-thane generally has very good insulating properties and can be used for potting and encapsulation. It is also an excellent material for mounting conductive rails, particularly outside, where it not only provides good insulation but also does not deteriorate. Noise The combination of compressive and flex characteristics make Detectamet/Detecta-thane ideal for breaking noise transmission paths. It makes superb heavy duty machine mounts.
