The development of inorganic filled polypropylene load materials is very rapid, which is due to the addition of inorganic fillers, reducing the shrinkage of plastic products, improve the dimensional stability, overcome the warping deformation of the products, while the heat resistance of the products, stiffness is also obtained, reducing the cost, commonly used inorganic fillers are talc, calcium carbonate and so on.
inorganic material filled polypropylene load material development is very rapid, this is due to the addition of inorganic filler, reduce the shrinkage of plastic products, improve the dimensional stability, overcome the warpage of the product, while the heat resistance of the product, stiffness is also obtained, reduce the cost, commonly used inorganic filler talc, calcium carbonate and so on.
Due to the difference in the properties of inorganic fillers and plastics and the affinity between the two, with the addition of fillers, the elongation at break, impact toughness and fluidity of the material will go down the well, which will bring difficulties to the design of materials and the teaching of products.
Barium sulfate filled polypropylene material is a kind of new composite material with high filling, high stiffness, high toughness and high elongation. New and more capable of physical mechanics.
