In the PU foam market, it is divided into two types: manual type and gun type. If you don’t know which PU foam is good, you might as well learn from the following aspects.
Check out the gun effect
If it is gun-type PU foam, check whether the glue is smooth and whether the foam effect is ideal. Normally, the foam should not be too thin or too thick, otherwise it will affect the filling effect.
Test it yourself
Before purchasing, you can spray PU foam on the newspaper to see if the ends of the foam are lifted. When this happens, the foam shrinkage is too high. If there is no warping, it means that the foam is of good quality and can perform stably. Cooperate with powerful suppliers, more assured, not only can focus on PU foam research, but also provide customized PU foam application solutions, which are widely used in new energy, military, medical, aviation, ships, electronics, Automotive, instrument, power supply, high-speed rail and other industries.
Look at the facet of the foam
In order to choose a better quality PU foam, it is recommended to cut the foam and take a look. Check whether the internal structure is uniform and fine. If the cells are large, the density is not good and it is not suitable for purchase.
Observe the foam surface
Take a closer look at the surface of the foam, the high-quality foam has a smooth and shiny surface, not as flat as the poor-quality foam surface. Look at the size of the cell, the high-quality foam is round and full, while the poor foam is small and collapsed, and has no high use value.
Touch the foam surface
Try it with your hand to see if the foam is elastic. Good foam has good elasticity, while poor foam feels hard and has a brittleness that cannot resist external extrusion.
