Here is the rubber compatibility chart that rates all popular rubber materials that comes into contact with various chemicals. Use this rubber chemical resistance chart to make sure that the elastomer or O-ring seal you choose will be compatible with the particular environment.

Plasticizers: Types, Uses, Classification, Selection &

Plasticizers are commonly classified based on their chemical composition. It is possible to understand the influence of structural elements (e.g. different alcohols in a homologous series of phthalates, adipates, etc.) on the properties of plasticizers and their effect Why Do PVC Pipes Crack & Become Brittle? | HunkerPVC pipe can become brittle due to chemical exposure. As a polymer, chemicals can have a profound negative effect on the makeup of PVC, causing loosening of bonds between molecules in the plastic and hastening the rate of plasticizer migration out of the pipe. PVC drains can become brittle if exposed to large amounts of chemicals, such as those

Shore Hardness Chart – Measuring Hardness of Thermoplastic

20/9/2017 · Thermoplastic Elastomers, or Thermoplastic Rubber compounds, as they're sometimes called, are a class of materials that behave a lot like rubber, but process like plastic.TPEs consist of hard and soft phase systems in the form of blends, alloys, or copolymers. Ductile / Brittle Transition Temperature – Plastics Standard to measure Ductile / Brittle Transition Temperature is ISO 6603-2 (multi-axial instrumented impact). It specifies a test method for the determination of puncture impact properties of rigid plastics, in the form of flat specimens, using instruments for measuring force and deflection. It is applicable if a force-deflection or force-time

Types and Causes of Concrete Deterioration

Corrosion of reinforcing steel and other embedded metals is the leading cause of deterioration in concrete. When steel corrodes, the resulting rust occupies a greater volume than the steel. This expan-sion creates tensile stresses in the concrete, which can Recent advances in bio‐based epoxy resins and bio‐based epox 13/7/2016 · To improve the mechanical properties of ESO-based polymers, ESO has been mixed with petroleum-based resins to create thermosetting polymers with minimal petroleum-based content. 59 Such is the case in a 2015 study by Cavusoglu and Çayli where ESO was polymerized with maleate half-esters of oil-soluble resols, p-tertiary butyl phenol (p-TBP) and p-nonyl phenol (p-NP), to yield tough

Everything You Need to Know About ABS Plastic

Acrylonitrile Butadiene Styrene (ABS) is an opaque thermoplastic and amorphous polymer. “Thermoplastic” (as opposed to “thermoset”) refers to the way the material responds to heat. Thermoplastics become liquid (i.e. have a “glass transition”) at a certain temperature (221 degrees Fahrenheit in the case of ABS plastic).
