Pearl cotton can not only package a lot of things, but also make a lot of things. Its advantages can also reflect its good performance. Its tube rod is also a derivative of pearl cotton production. How should we judge its quality? We should pay attention to these points when judging:
1. Feel the texture. The rough one is probably mixed with impurities.
2. Kneading hardness. It is not EPE pearl cotton tube with suitable hardness and deformation.
3. Look at the color. There are several important gray green, consumers often think that white is good, the color is not decisive quality of the scale.
4. Smell. The important material is polypropylene. Good EPE pearl cotton tube has no smell, and the bad one has strange smell. It is probably mixed with polyethylene, not polypropylene.
5. Flexibility. Good PP-R pipe, good resilience, easy to crush, natural is not a good PP-R pipe. But hardness is not good elasticity, some manufacturers through the participation of too much calcium carbonate and other impurities to improve hardness, how can not be broken, used for a long time easy to brittle.
6. Smell the smoke. PE pipe strips mixed with plastic and other impurities will emit black smoke with pungent smell. The material is clean and has no smoke after melting.
It can be seen that pearl cotton is widely used. We can judge the quality of the tube rod according to the above methods, smell the smell, measure the hardness, and look at the color. According to these, we can help you correctly judge and avoid buying fake goods.
