Benzoflex rf 532 plasticizer benzoflex rf 532 is a benzoate ester specifically designed for resilient vinyl flooring applications.
Plasticizer migration vinyl flooring.

Benzoflex rf 532 is a high solvating plasticizer that may be used in foam clear or wear layers.

Incorporation into the wear or clear layers of a construct imparts excellent stain and uv resistance.
There exist important industrial applications such as hoses or plastic windows dealing with closely combining plasticized and rigid poly vinyl chloride.
They re also used in adhesives to improve tack or stickiness.
Because plasticizer migration from vinyls to the adhesive bond line can cause problems adhesives selected must be tested for their compatibility with the plasticizer.
Heat will accelerate this activity.
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 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.
Nevertheless migration of plasticizer causes severe variation of the mechanical performance of the end products.
Plasticizer migration happens when the pvc found in some flooring tiles or backings reacts with adhesive left over from previous installations.
Over time the plasticiser chemical in the vinyl migrates out and is absorbed into.
Plasticiser migration plasticisers are used in vinyl flooring products to soften the material and improve its flexibility.
It s when the plasticizer chemicals within vinyl plastic or rubber migrates out and is absorbed by surrounding materials.
When vinyl is made the resin and plasticiser are held together through electromotive forces as a solid solution.
Two common plasticisers are mineral oil and hydrocarbon oil.
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.
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.
When plasticizer migration happens sheet vinyl can soften discolor loosen crack or turn brittle.
Plasticizers can also migrate from one plasticized material to another substrate.
