Weather-resistant PP

characteristic

1. Through the addition of additives and special copolymerization modification technology, the resistance to ultraviolet rays is significantly improved, the speed of photooxidation and degradation is reduced, it can withstand the influence of ultraviolet rays, oxidation and humid environments, and the weather resistance is significantly improved, and the outdoor life of the product is significantly improved.

2. The density is about 0.91g/cm³, good water stability, low water absorption, good moldability, good surface gloss

3. Good heat resistance, continuous use temperature is 110-120℃, and can withstand high temperature of 150℃ in the short term. It can be used for steam disinfection. Its melting point is 164-176℃, and the Vica softening point is 150℃.

4 Except for strong acids such as concentrated sulfuric acid and concentrated nitric acid, it is relatively stable for various other chemical reagents, but low molecular weight aliphatic hydrocarbons, aromatic hydrocarbons and chloride hydrocarbons can soften and swell PP.

5 Through the related improvement of additives, the low temperature impact resistance of the material is significantly improved

6 The tensile strength can reach about 30MPa and has outstanding resistance to bending fatigue. Through copolymerization and other means, the impact strength of the material is significantly improved while maintaining a certain degree of rigidity.

7 Good processing performance, can be used for injection molding, extrusion, blow molding and other molding methods

Application

Household appliances shells, outdoor plastic products
