How to distinguish adulterated sponges from pure sponges:
Look:The sponge process is mainly divided into two categories: foaming and PU. Doping makes the fake sponge foam uneven and the pores are large. The pure sponge pores are small and uniform;
touch:pure sponge feels smooth and smooth, doping makes the fake sponge feel rough, very poor elasticity.
extrusion:seemingly the same thickness and hardness of the sponge, doping so that the fake sponge is easy to appear concave once squeezed, sit for a long time can not play up; pure sponge support strong, long-term extrusion is also difficult to deform;
the price:doping makes the fake sponge greatly reduce the cost due to the addition of stone powder, the price is low; the polyurethane material used in pure sponge is more expensive than the adulterated sponge;
life:adulterated sponge because of the addition of stone powder, hand rubbing, easy to slip down; pure sponge is durable;
Comparison of tensile strength between adulterated sponge and pure sponge: the same sponge with the same appearance, the longer the tensile strength, the better the tensile strength.
Comparison of breaking strength between adulterated sponge and pure sponge:the same sponge as the appearance, pure sponge can be loaded with strong strength
