PVC or Vinyl Foam
PVC Foam or Vinyl Foam as it is sometimes known is a soft, low density closed cell foam which is conformable and HF (High Frequency) weldable. It is made up of polarized molecules (called dipoles).
When a high frequency alternating voltage is passed across it, the dipoles rotate within the foam at macroscopic level. This causes internal friction which generates heat and melts the foam to form a molten foam where the high frequency is applied. The HF welding tool is made of brass of and it is where the tool is in contact with the foam where the welding takes place.
Our foams have a good Tear Seal
Typically the density is 120Kg/m³ (though other densities are available) and is made in roll format for conversion as plain or self adhesive backed rolls or the can be log cut into coils. Higher densities are available and the higher the density the thinner the foam can be produced. A new low density foam was developed for the Stationery Market when a leading open cell PVC foam manufacturer ceased trading.
VP100
A PVC Vinyl foam of low density (100Kg/m3) with a skin on both sides.
Availability: 2 or 3mm white in roll format approx. 40m x 1.45m. VP100 has been replacing “ Duflex Open Cell Vinyl foam” in the market.
QR120 (quick recovery)
A PVC Vinyl foam of 120 Kg/m³. This is the basic grade that is used to create SR100.
Available in Black or White and widths 1m as standard up to 1.4m and a thickness from 2mm to 20mm.
SR100 (slow recovery)
A PVC Vinyl foam of 120 Kg/m³ vinyl foam with a skin on both sides. This is a product which has had its cells crushed to create a super soft, slow recovery grade.
Available in Black or White and widths 1m as standard up to 1.4m and a thickness from 2mm to 20mm
*150 and 200 Kg/m³ grades are also available in Quick Recovery versions
Typical Uses
