Pearl cotton bar is also from polyethylene foam, through a process of the machine made rod material. Pearl cotton should be very clear to all of you, it is composed of numerous independent bubbles produced by physical foaming of low-density polyethylene grease. It overcomes the shortcomings of ordinary foam adhesive, such as fragile, deformation and poor recovery. Pearl cotton bar not only has the above characteristics, but also has many advantages, such as water-proof and moisture-proof, shockproof, sound insulation, heat preservation, good plasticity, strong toughness, recycling, environmental protection, strong impact resistance and many other advantages, but also has good chemical resistance.

Application field: pearl cotton bar is widely used in our daily life, so how to distinguish the quality of pearl cotton tube rod when purchasing? Here we can introduce the following:
1. Touch the texture. Generally speaking, the coarse PE particles are likely to be mixed with impurities;
2. "Pinch" hardness. PE pipe strip has considerable hardness, and the deformed pipe can be easily pinched, which is definitely not PE pipe strip;
3. Look at the color. PE pipe is mainly white gray green, consumers often think that white is good, in fact, color is not the standard to judge the quality;
4. Smell the smell. The main material of PE pipe is polypropylene. The good pipe has no smell, and the bad pipe has a strange smell. It is likely that polyethylene is mixed with it instead of polypropylene. Master these technologies can be very good to screen high-quality products.
Pearl cotton bar is used in children's toys, soft ring filler materials, children's toys, soft ring materials to fill expansion joints, widely used in cement block expansion joints.
Compared with the traditional packaging material bar which is fragile, fragile and polluted, pearl cotton bar will become a powerful force in the packaging material market!
