reagents and stress level in the plastic parts all considerably effect the chemical resistance and consequently your material choice.For example PC 1000,PEI 1000,PSU 1000 and PPSU 1000,because of their amorphous chemical structure,are sensitive to stress cracking when in contact with polar organic solvents.Environments,which areABS has reasonable chemical resistance but I have seen it suffer from environmental stress cracking when under stress and exposed to oil residues o1My experience with ASA is that it is better than ABS to UV,but more susceptible to environmental stress crack. Regards eng-tips,by professionalAs with any product there are differences between manufacturer so ABS and ASA each describe a range of materials with different properties.Let meThank you for the suggestion to try ASA.However,because of plumbing codes (this is a closet flange) we must stay with ABS.

How Do Engineers Evaluate Plastic Materials and Material

The term refers to the maximum stress a particular plastic can withstand while being pulled or stretched without breaking.The highest point of the stress strain curve is the UTS.The measure of unit for UTS is MPa or psi.Some plastic materials will break sharply-this is stress resistance plastic oil tanked brittle failure.Other materials,such as most metals,will How To Fix A Crack In A Plastic Gas Tank - CarCareHuntSafety First3 Methods For Fixing A Crack in Your Plastic Fuel TankFinal ThoughtsBefore we jump into possible fixes for a cracked gas tank,its important to take some safety precautions first.The bottom line is that youll be working with a part that is meant to store fuel.That presents a pretty serious fire hazard.First and foremost,take steps to remove all the fuel from your tank before you start in with the repairs.Some fuel tanks actually have a small drain plug that can be removed to drain fuel.If your tank has a plSee more on carcarehuntThe Big Difference Between HDPE and Cross-Linked The result is a plastic that possesses impact resistance,tensile strength and resistance to fracture that linear polyethylene cant match.These qualities make cross-linked polyethylene an excellent choice when tank integrity is critical.The chemical resistance,heat resistanceImages of Stress Resistance Plastic Oil Tank imagesChemical resistance plastics Röchling ENTanks for storing chemical media For use in tanks for storing chemical media,as well as excellent chemical resistance,plastics must also have a high resistance to thermal and static stress.Typical media are hydrochloric acid and sulphuric acid.
