What is BS 4835- Plasticizer esters about?
BS 4835 describes general methods of test applicable to organic ester type plasticizers containing only carbon, hydrogen and oxygen but excluding esters of phenols and esters of hydroxy-acids.
An ester plasticizer, in its simplest concept, is a high-boiling organic solvent that when added to an elastomeric polymer reduces stiffness and permits easier processing.
Who is BS 4835- Plasticizer esters for?
BS 4835 on methods of test for plasticizer esters is useful for:
- Chemical manufacturers
- Chemical engineers
- Testing laboratories
Why should you use BS 4835- Plasticizer esters?
Plasticizer Esters are produced by esterification of phthalic anhydride or phthalic acid obtained by the oxidation of orthoxylene or naphthalene. BS 4835 provides you with methods for organic ester type plasticizers.
BS 4835 provides you with measurement colour and colour after heat treatment. BS 4835 provides you with the methods to determine water content, ash, acidity to phenolphthalein, ester content, saponification and ester values, viscosity, matter oxidizable by potassium dichromate, density at 20 °C, crystallizing point, refractive index and flashpoint.
