Plasticizer Migration Vinyl Flooring

Plasticizer migration can cause flooring tiles to discolor soften or in the worst case scenario slide around as the adhesives dissolve into an oozing mess and stop holding the floor tiles in place.

Plasticizer migration vinyl flooring.

Plasticizers can also migrate from one plasticized material to another substrate. They re also used in adhesives to improve tack or stickiness. Heat will accelerate this activity. It s when the plasticizer chemicals within vinyl plastic or rubber migrates out and is absorbed by surrounding materials.

Benzoflex rf 532 is a high solvating plasticizer that may be used in foam clear or wear layers. Because plasticizer migration from vinyls to the adhesive bond line can cause problems adhesives selected must be tested for their compatibility with the plasticizer. Benzoflex rf 532 plasticizer benzoflex rf 532 is a benzoate ester specifically designed for resilient vinyl flooring applications.

For example a rubber mat placed on a bathroom floor covered with vinyl may eventually leave a yellowish stain where the mat made contact with the vinyl. The best way to avoid this in sheet vinyl is to prime and seal the sub floor. For example plasticizer can and does migrate from vinyl to the adhesive adhering it to a substrate. Incorporation into the wear or clear layers of a construct imparts excellent stain and uv resistance.

Plasticizer migration happens when the pvc found in some flooring tiles or backings reacts with adhesive left over from previous installations. Nevertheless migration of plasticizer causes severe variation of the mechanical performance of the end products. When vinyl is made the resin and plasticiser are held together through electromotive forces as a solid solution. Plasticiser migration plasticisers are used in vinyl flooring products to soften the material and improve its flexibility.

Over time the plasticiser chemical in the vinyl migrates out and is absorbed into. There are many non reactive floor sealants available that can minimize the effects of a reaction and cover up old adhesive that may trigger them as well. What is plasticizer migration. There exist important industrial applications such as hoses or plastic windows dealing with closely combining plasticized and rigid poly vinyl chloride.

When plasticizer migration happens sheet vinyl can soften discolor loosen crack or turn brittle. This is what is occurring in our example above.
