PP products are light in weight, good in toughness and good in chemical resistance. Disadvantages of PP: low dimensional accuracy, insufficient rigidity, poor weather resistance, easy to produce "copper damage", it has the phenomenon of t shrinkage, easy aging, brittle, easy deformation after demoulding. In daily life, the commonly used fresh-kee box is made of PP material. In order to prevent photoaging, it is necessary to add UV absorber into PP, which can transform the UV absorption of 290 ~ 400nm into non destructive long wavelength light. For the PP plastic products buried in the soil or used indoors in the dark, only the main and auxiliary antioxidants can be added, and the ultraviolet absorber is not needed. The shrinkage and crystallinity of PP are lower than that of PE. PP has a certain permeability to oxygen, carbon dioxide and water vapor. Compared with nylon PA and polyester PET, PP is much worse than nylon PA and polyester PET, but it is much worse for high barrier plastics such as PVDC and EVOH. But compared with other non plastic materials, its air tightness is quite good. The air tightness can be greatly improved by adding barrier materials or coating barrier plastics on the surface. PP is a non-polar polymer with good propertiesPP的綜合性能優于PE料。PP產品質輕、韌性好、耐化學性好。PP的缺點:尺寸精度低、剛性不足、耐候性差、易產生“銅害”,它具有后收縮現象,脫模后,易老化、變脆、易變形。日常生活中,常用的保鮮盒就是由PP材料制成。為防止光老化需要在PP中加入紫外線吸收劑,它可將波290~400nm的紫外線吸收激化轉化為沒有破壞性的較長波長的光線。對于埋在土壤中或在室內避光使用的PP 塑料制品僅加入主輔抗氧劑即可,無須加入紫外線吸收劑。PP的收縮率和結晶度比PE低。PP對氧氣、和水蒸汽都有一定的透過性,比起尼龍PA和聚酯PET都有明顯差距,對于高阻隔性塑料,如PVDC、EVOH等就差得更多了。但與其它非塑料材料相比其氣密性還是相當好的。通過添加阻隔性材料或在表面涂敷阻隔性塑料,可以提高其氣密性。PP屬于非極性聚合物,具有良好的電絕緣性,且PP吸水性較低,電絕緣性不會受到濕度的影響。PP的介電常數、介質損耗因數都很小,不受頻率及溫度的影響。PP的介電強度很高,且隨溫度上升而。這些都是在濕、熱環境下對電氣絕緣材料有利的。另一方面PP的表面電阻很高,在一些場合使用必須行抗靜電處理Although PP has higher mechanical strength and modulus than recycled PE, the impact resistance, especially stress cracking resistance, and low temperature performance of recycled PP are poor, like the new PP resin. These properties are determined by the aggregation structure and macromolecular chain structure of PP, so it can be modified by polyethylene. When the blends of recycled PE (LDPE, HDPE) and PP are made, if there are more recycled PP materials, the alloy can be directly prepared. For example, if 10% - 25% HDPE is added into PP, the impact strength of the modified blend is increased by more than 8 times than that of PP at - 20 ℃, and the processing fluidity is increased, so it can be applied to the molding of large containers. In terms of structure, the addition of PE destroys the crystallization of PP, such as the fragmentation of macrospherulites, and also reduces the crystallinity of PP; if EPDM is added into the system, the crystallization of PP is also reduced. About 5% can improve the compatibility of PP and PE, and the impact strength can also be improved by adding a small amount of EPR rubber.PP力學性能 的拉伸強度和剛性都比較好,但沖擊強度較差,特別是低溫時耐沖擊性差。此外,如果制品成型時存在取向或應力,沖擊強度也會顯著降低。雖然抗沖擊強度差,但經過填充或增強等改性后,其機械性能在許多領域可與成本較高的工程塑料相競爭。PP 的表面硬度在五類通用塑料中屬低等,僅比PE 好一些。當結晶度較高時,硬度也相應增加一些,但仍不及PVC、PS、ABS 等。熱性質在通用塑料中,PP的耐熱性是。PP 塑料制品可在100℃下長時間工作,在無外力作用時,PP制品被加熱至150℃時也不會變形。我們的優勢:我們的產品均能為客戶提供***報告與COA出廠報告我們的市場行情信息準確我們及時提供售后技術支持我們的貨源充足穩定
