For these reasons, the compressive load is not normally given at break, but is instead given at a defined deformation point (commonly 1%, 2% or 10%). Find books Alloys, or mechanical blends of two or more polymers, improve performance and processability and lower material cost. Ductile plastics go through a period called “necking,” which is a localized reduction in cross-sectional area and happens during the plastic region of a stress-strain curve. Plastics … For others, the UTS is the stress recorded right before the specimen breaks. To normalize test results and allow for comparison, many tests follow a standardized procedure, whether from an international standards board or supplied from a vendor or customer. The fundamental mechanical material characteristics include: GCMS Testing Lab for Plastics and Polymers. The force being applied to the specimen is measured by a load indicator, which is normally called a load cell or pressure transducer. PROPERTIES OF PLASTICS Mechanical and Physical Properties of Plastics This section will acquaint the reader with the tech-nical terms and concepts used to describe the properties or performance of a material. Good electrical properties amongst others. Chapter 6-53 Ensinger products with the best stiffness values include TECASINT 4111 (PI), TECAPEEK (PEEK), TECAST (PA 6 C), TECAFORM AD (POM-H), and TECAPET (PET). This website requires certain cookies to work and uses other cookies to help you have the best experience. High electrical and insulation properties 4. Mechanical Properties of Plastics. In particular, the methods to recycle plastic waste, the effects of recycled plastic on the physical and mechanical properties of cement-based materials, and their effective usage were investigated. Elongation is defined as the amount that a material will stretch or deform when a stress is applied. PVC, or polyvinyl chloride, is a common thermoplastic and has uses in a variety of applications. Spectroscopy. Download books for free. The experimental results are reported in dimensionless form, i.e., the value relative to each blend is divided by the corresponding value of the unblended matrix. Properties for some of the materials above represent a specific grade, formulation, specification, or brand including the following: Acetal (Homopolymer), Acrylic (Continuously Processed), DuPont™ Vespel® Polyimide (Vespel® SP-1), ECTFE (Halar® 901), ETFE (Tefzel® HT-2183), Expanded PVC (Celtec® 3mm-12mm thickness), KYDEX® Thermoplastic Sheet (KYDEX® 100), Noryl® (Modified PPO), Nylon (6/6 … All Rights Reserved BNP Media. 9 BAHADUR SHAH ZAFAR MARG NEW DELHI 110002 Price Group 2 Please ask your Curbell Plastics representative for more specific information about an individual brand. MECHANICAL PROPERTIES OF POLYMERS Anil K. Bhowmick Indian Institute of Technology, Kharagpur, India Keywords: Mechanical properties, dynamic mechanical properties, stress, strain, polymer, plastics, elastomers, rubber Contents 1. Chapter 6-4 Elastic means reversible! In this case, and in many other cases, testing and analyzing both the raw material and the finished product were critical to the success of the final design. High extrusion speed on standard lines 7. Other … Because every mechanical system is subjected to loads during operation, it is important to understand how the materials that make up those mechanical systems behave. It is shown being clamped by a set of pneumatic grips within a material testing system. In general, mechanical properties are best increased by adding reinforcing fibers made of glass, metal, carbon or other materials. Technical Information|Properties|Mechanical properties Ⅰ. Tensile characteristics . Polypropylene has applications both as a plastic and a fiber in: ... Due to its low cost, outstanding mechanical properties and moldability, polypropylene is widely used in automotive parts. Flexural strength and tensile strength of plastic are two of the most commonly used values to compare materials. Study on Mechanical Properties of Concrete Using Plastic Waste as an Aggregate | Jaivignesh, B; Sofi, A | download | BookSC. Materials: The kenaf stalks were harvested from … The difference could stem from the fact that most of the published literature available on thermoplastic materials is based on results from injection moulded specimens, while the data provided on Ensinger datasheets is obtained from specimens machined from extruded samples. Though the characteristics of polycarbonate are similar to polymethyl methacrylate (PMMA, acrylic), but polycarbonate is stronger, usable in a wider temperature range (Melting point: 155°C) but more expensive. Ⅳ. Use our interactive properties table below to explore by property group, sort, or compare two or more plastic materials. It is also defined as polymers of long carbon chains. Testing standards determine which type of strain must be reported and will give the specification for the device being used to measure the change in length. The most common static mechanical properties measured during testing are ultimate tensile strength (UTS), elongation, modulus of elasticity, and yield. Stress, Strain, and Hooke’s Law. The glass fibre reinforced plastic (GFRP) had a fibre content varied by weight from 35 to 50% while the thicknesses of the laminate were 10 mm, 12 mm and 16 mm. Excessive deformation under load would thus not be a good indication for success in any real industrial application. Examples of plastic bodies: Wax, Clay, Plasticine . In order to do a through research, a few testing will be done on the panel itself such as Tensile testing, Flexural testing and Impact testing in order to observe its mechanical properties. You can filter down your options by property (mechanical, electrical…), applications, conversion mode and many more dimensions. It is important to understand the conditions that a product may endure to ensure that those conditions are replicated during testing. Figure 1: Nylon stress-strain curve. Mechanically tougher It should also be noted that the addition of carbon fibre or glass fibre reinforcement generally improves the compressive strength of the polymer, but the macroscopic effect is more visible in the long term rather than in short term load performance, due to the improvement of creep properties.
