PP plastic matching coating resin have what?

PP material is polypropylene, non-toxic, odorless, tasteless milky white high crystalline polymer, non-polar polymer, its surface free energy is small, low surface tension, generally 33mN/m (other materials such as steel 75 mM/m, glass 7375 mM/m). Theoretically speaking, if the surface tension of the object is lower than 33mN/m, the ordinary ink or adhesive cannot be firmly attached, so the surface must be treated.

PP plastic is currently one of the lightest varieties of all plastics. It is commonly used in various basins, furniture, films, woven bags, bottle caps, car bumpers, etc. Advantages: PP is light, has good toughness and good chemical resistance; Disadvantages: insufficient rigidity and poor weather resistance. For example, commonly used car bumpers are often placed outdoors and exposed to the sun. If the weather resistance is poor, they are easy to age and lose their original characteristics, but what we see is a painted bumper, even after a long time, Still relatively intact.

From the above simple review, we know that the performance requirements of PP coatings must be high. Our company has introduced a series of matching products for PP plastic coatings, which are currently divided into four categories: pp801 pp802 pp805 pp807. If you are interested, please contact us!
