Prevent Plasticizer Migration with Vinyl Bonding Solutions

vinyl bondingAccording to ChemistryViews.org, plasticizers are odorless, colorless and are mainly phthalates that are used to increase the elasticity of material such as Polyvinyl chloride (PVC). PVC is one of the top three most widely used synthetic plastic polymers following polyethylene and polypropylene.

Where Plasticizers are Used

PVC is often used to make things like vinyl flooring, siding, pipes, plumbing parts, hoses, automotive parts, cable and wire coatings, medical devices and more.  You can find PVC in many products such as housewares, upholstery, food packaging products, roofing membranes, the possibilities are endless.  Vinyl adhesives are used to bond vinyl to metal and other vinyl lamination applications to produce a wide variety of products.

Plasticizers are used in PVC to help make these products and can also be found in rubber products, adhesives, paints, and sealants for professional and industrial uses. The use of plasticizers in any application is strictly regulated.

Benefits of Plasticizers

Plasticizers are added to PVC formulations to add flexibility and softness. The use of plasticizers to make products bendable and flexible allows for a wide range of possibilities for new and existing applications. One of the greatest benefits that plasticizers provide is to add durability to products which provides benefits to many applications.

Plasticizers can help to provide longer-lasting performance of products, in some cases extending product performance to 50 years or more. Without the use of plasticizers, PVC would only be rigid such as the PVC type of pipes we are all familiar with.

Plasticizer Migration and Vinyl Bonding

Vinyl bonding poses unique challenges with many adhesives that risk impacting the integrity of the vinyl itself. Some applications require a pretreatment process to assist in mitigating plasticizer migration. Plasticizer migration occurs when plasticizers migrate from one material to another, typically from the vinyl to the adhesive which adheres it to the substrate itself.  Plasticizer migration occurs over time and can be accelerated with heat.  Examples could be a dashboard in a vehicle that gets dry and cracked without proper lubrication such as spraying the material with an Armor All type of product.

The use of additives in vinyl materials, particularly plasticizers, poses unique challenges to vinyl bonding and can make it difficult to bond vinyl to metal and other substrates. Plasticizers are chemicals that are constantly moving.  Some plasticizers are more prone to migrate to the surface of vinyl which in turn can cause applied vinyl adhesives to separate and de-bond as adhesive failure occurs.
