Corrugated Plastic Sheet Factory introduced that plastic hollow sheets can be widely used in many aspects because of their compressive strength and impact resistance. However, the quality of plastic hollow sheets is immediately related to the compressive strength.

The high-toughness plastic hollow board has the characteristics of more durability and stronger bearing capacity in normal applications, which can greatly improve the quality of the plastic hollow board and reduce the damage in the normal application, and the compressive strength of the plastic hollow board Related to many factors below, this is also the direction for hollow board manufacturers to improve the compressive strength:

The compressive strength of the plastic hollow board is expanded with the increase of butadiene content. In addition, the Vicat softening temperature of the PP hollow board is 150 ℃, because of the higher grain size, the surface bending stiffness and scratch resistance of this kind of raw material The mark characteristics are very good, and there will be no stress cracking problems in the natural environment. The PP can be modified by adding glass fiber, metal material preservative or thermoplastic vulcanizate. The loss rate of PP is in the range of 1-40. Low MFR PP raw materials have good impact resistance characteristics but low tensile compressive strength.

Because of the harm of crystals, the shrinkage rate of the plastic hollow board is generally very high, generally 1.8~2.5%, and the azimuth and symmetry performance of the shrinkage rate is much better than that of raw materials such as PE-HD. At this time, 30% of laminated glass can be added for corrosion protection. The agent can reduce the shrinkage rate to 0.7%, and the raw materials of the homopolymer and polymer plastic hollow boards have high-quality compressive strength characteristics. In addition, materials such as antistatic masterbatch and flame retardant rate can be added to improve the antistatic and flame retardant performance of the plastic hollow board!

Through the above introduction, China Corrugated Plastic Case Wholesaler hopes that you can simply refer to the content of this article in future use.
