Plastics, Elastomers and Polymers Reference Materials

Description: Engineering plastics have been used extensively in automobiles in a variety of applications such as grille opening retainers, bumpers and decorative panels. Recently, engineering plastics are also ...

Description: With liquid crystal polymers (LCPs), the medical device designer can improve part economics as well as performance and processing compared with metals and other plastic materials. LCPs eliminate ...

Description: For the appliance engineer, plastic gears are a powerful means to cut cost, weight, noise and wear. They also open new opportunities for smaller, more efficient drives. What are the payoffs when using ...

Description: Over a quarter century ago, lasers were thought of as "tools of destruction." From cutting through steel to use as weapons, lasers were powerful devices and thought to only be used that way. Of course ...

Description: Many electrical, automotive, industrial and other applications call for costeffective materials with superior mechanical and electrical performance at elevated temperatures. During the past ...

Description: Auto fuel systems, long challenging environments for engineering thermoplastics, became more so during the past decade as new fuels were introduced and fuel temperatures rose. The demands on plastics ...

Description: Polymer selection helps automotive fuel-system components survive for the life of the vehicle. ...

Description: Classic fracture analysis of unfilled plastics has welldefined and well-documented methods for determining what happened to broken parts. However, introducing long-fibers into the picture obscures ...

Description: ULTRA HIGH MOLECULAR WEIGHT P O LYETHYLENE (UHMWPE) is a line a r, low-pre s s u re, Ziegler-type catalyst, polyethylene resin. Its weight-average molecular weight of 4 X 106 is appro x i m a t e l y ...

Description: Unfilled (neat) liquid crystal polymers (LCP) have excellent thermal and dimensional stability, as well as high rigidity, strength, and chemical resistance. LCP parts can be molded with great ...

Description: For mechanical engineers, plastic gears are a powerful means of cutting drive-cost, weight, noise and wear. Plastic gears also open new opportunities for smaller, more efficient transmissions in many ...

Description: People usually associate color with physical objects that are viewed in sharp contrast to their surroundings: be it a beautiful flower arrangement, or a colorful spinnaker on a sailboat against a ...

Description: The use of plastics in place of metals is helping many manufacturers maintain profit margins as costs and competition increase. These manufacturers are finding that the switch also improves products, ...

Description: We create a case study for every new project. In this example the critical areas were: nominal wall thickness, boss wall stock thickness relative to nominal wall thickness, potential sinks from ...

Description: The pressure on design engineers to make the right decisions on prototyping is more important today than ever because of speed-to-market requirements, increasing cost restraints, and the escalating ...

Description: The road to a plastic part that functions as designed is paved with good intentions. Best-laid plans can be disrupted by failure to understand unique problems presented by the injection molding ...

Description: One of the least understood and most erroneously specified areas in the design field is high-temperature plastics. The phrase is widely used but difficult to define. What plastics can genuinely be ...

Description: Design engineers with considerable experience in metals may overlook the effect creep can have on the long-term performance of a plastic part, particularly when applications involve high operating ...
