Plasticizer Migration Vinyl Flooring
Over time the plasticiser chemical in the vinyl migrates out and is absorbed into.
Plasticizer migration vinyl flooring. Benzoflex rf 532 is a high solvating plasticizer that may be used in foam clear or wear layers. This is what is occurring in our example above. What is plasticizer migration. 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.
There exist important industrial applications such as hoses or plastic windows dealing with closely combining plasticized and rigid poly vinyl chloride. Nevertheless migration of plasticizer causes severe variation of the mechanical performance of the end products. Two common plasticisers are mineral oil and hydrocarbon oil. Most vinyl flooring contains plasticizers in order to confer flexibility and traditionally those plasticizers have been made from petroleum based phthalates though in recent years most suppliers.
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. Benzoflex rf 532 plasticizer benzoflex rf 532 is a benzoate ester specifically designed for resilient vinyl flooring applications. Plasticizers can also migrate from one plasticized material to another substrate. For example plasticizer can and does migrate from vinyl to the adhesive adhering it to a substrate.
The best way to avoid this in sheet vinyl is to prime and seal the sub floor. Landrock in adhesives technology handbook third edition 20156 3 28 polyvinyl chloride pvc solvent cementing is usually used for polyvinyl chloride pvc. Because plasticizer migration from vinyls to the adhesive bond line can cause problems adhesives selected must be tested for their compatibility with the plasticizer. When plasticizer migration happens sheet vinyl can soften discolor loosen crack or turn brittle.
Heat will accelerate this activity. 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. It s when the plasticizer chemicals within vinyl plastic or rubber migrates out and is absorbed by surrounding materials. Plasticiser migration plasticisers are used in vinyl flooring products to soften the material and improve its flexibility.
Plasticizer migration happens when the pvc found in some flooring tiles or backings reacts with adhesive left over from previous installations. They re also used in adhesives to improve tack or stickiness.
