Modification of PP, so the name implies is on the basis of the PP material to improve some performance, such as impact resistance, tensile strength. Concrete is divided into the following categories.
1. PP + powder or mica/borax - level is generally used in the production of heat-resistant modified PP. Main use used in home appliances shell, such as iron, rice cooker shell, etc.
2. PP + calcium carbonate - this actually not modification, because add calcium carbonate is expanded, the physical properties of materials without any improvement, on the contrary the toughness and strength is reduced, and good processability flow, adding calcium carbonate is mainly to reduce the cost.
3. PP + POE or EVA -. Modified mainly enhanced toughness and impact resistance of PP, sports equipment, automobile thing worthy of (such as bumper) can be used to..
4. PP + glass fiber GF - mainly reinforced material heat resistance and rigidity, reducing the size of the material shrinkage deformation. Much to tool shell, auto parts and so on.
5. PP + flame retardant, flame retardant reinforced material, mainly used in electrical accessories, instruments and meters.
