    Amorphous vs. Crystalline Polymers

    Polymers are unlike other types of materials because of their high molecular weight. Molecular weight is the value used to express the size of a molecule. Water, for example, has a molecular weight of 18 atomic mass units. Polymers are much larger, with molecular weights ranging from tens of thousa... read more

    The knowlage of Nitrile Elastomers

    Nitrile elastomers are emulsion polymers produced using rubber polymerization techniques. Also known as nitrile emulsions or nitrile latexes, these are dispersions of acrylonitrile and butadiene — or sometimes styrene — in water. Nitrile elastomers are true colloids, defined as a homogenous amorpho... read more

  • Moisture Vapor Transmission Rate

    Moisture Vapor Transmission Rate

    Moisture vapor transmission rate, also called water vapor transmission rate (WVTR), is the amount of water vapor that passes through a substance or material over a specific period of time.  Having the ability to measure MVTR is a key factor in controlling moisture in a wide range of products. Manuf... read more

    An Introduction to Vinyl Acetate-Based Polymers

    Vinyl acetate monomers (VAM) are essential building blocks for a large number of water-based polymers. Vinyl acetate is prepared from ethylene by reacting it with oxygen and acetic acid over a palladium catalyst. The basic chemical reaction is shown below, along with the chemical structure of vinyl... read more
