灰色PPR棒是采用氣相共聚工藝使5%左右PE在PP的分子鏈中隨機地均勻聚合(無規共聚)而成為新一代PPR棒材料,是耐酸堿耐-腐蝕性最好的塑料棒。
它的主要特點是：
1：強度高。
耐酸堿耐腐蝕性的塑料棒 灰色PPR擁有良好的抗沖擊性能和長期蠕變性能 抗酸堿腐蝕性是最好的、抗溶解性。
2：耐腐蝕PPR 棒/灰色PPR棒/水灰色PPR棒/：英文名稱 Polypropylene 灰色PP 聚丙烯棒---具有高剛度，高硬度和高強度。PP R材料能承受張拉應力并易焊接

PPR棒的耐腐蝕
    PPR棒耐壓防震，耐沖擊，耐油、耐酸堿PPR棒具有優異的耐化學物品腐蝕性能
    
    PPR棒的用途:異型法蘭專用PPR棒,異型PPR法蘭,化工管道法蘭專用PPR棒,一般用PPR棒材加工,PPR棒外徑在500毫米-400MM-300MM-250MMPPR棒材長度為一米長,可以訂做二米長度
    一、耐腐蝕性：PPR棒材具有優秀的耐酸、耐堿、耐化學藥品，抗老化等性能，在同等條件下使用(相同介質，相同溫度，相同壓力)PP管至少比其它材質的管材壽命高出10年。PPR棒同時其材料特性還包括高強度，高剛度和高硬度，工作溫度范圍從零下15度到160度，可粘接，可焊接。 特性:耐腐蝕強，最適用于化工業之防蝕性設備。加工容易：切斷、焊接、。 高強度PPR棒，高剛度和高硬度；良好的電氣絕緣性；化工穩定性好；可自熄滅；低吸水性；易粘接，易油漆。 價格低廉。
    二、比重小、價格低，節省工程造價，PPR棒材質更輕，僅為PC、UPVC管材重量的60%，ABS管材的70%
    三、獨特的無毒性：PPR棒材是國家權威鑒定部門認可的無毒產品，即而成為醫療、制藥、環保，水處理、食品加工制造業的最佳適用產品。
    四、獨有的耐高溫高壓性：PPR棒耐溫性能卓越，在+110度以內，(常壓)可以長期使用，保證管材不變形、不開裂、不滲漏。
    五、PPR機械強度大：PPR棒具有極強的耐水壓、耐氣壓、耐沖擊能力，各方面指標都優于其它管材
    六、PPR棒機械加工性：PPR棒材具有好的機械加工性，如車、銑、刨、鉆、等、且加工簡單、易操作。
    七 電氣絕緣性好：PPR棒具有很好的電氣絕緣性，可廣泛應用于電信、電力的配制領域。
    良好的密封性能：PPR棒材可采用熱熔以及焊接和絲扣方法連接均具有良好的密封性能。
    　、焊接性能與管件：連接采用熱熔與焊接方式，操作簡單方便
    
    
    
    β（Beta）-PPR棒俗稱PP棒,米黃色β（Beta）-PPR棒俗稱PPR,有灰色,白色,β（Beta）-PPH棒俗稱PPR棒,米黃色PPR/，它經過β（Beta）-改性具有細膩的結晶結構，不但具有優良的耐化學性、耐高溫性以及良好的抗蠕變性，而且在低溫下還具有優異的抗沖擊性。增加了靜液壓強度，增進了耐化學品性能。根據PPR材料的特性，將PPR棒材制作為耐蝕設備配件，法蘭，廣泛應用于化工、冶金和電子等領域方面Stick uses of PPR: the profiled flange dedicated PPR rods, shaped PPR flange, chemical pipe flange PPR rods, general PPR Barstock PPR Rod Diameter 500 mm-400MM-300MM-250MMPPR bar length for meters long, two meters length can be customized
    Corrosion resistance: PPR bars have excellent resistance to acid, alkali, chemical resistance, anti-aging properties, under the same conditions (the same media, the same temperature, the same pressure) PP pipe at least compared to other pipe material life than 10 years.
    Second, the proportion of small, low-price project cost savings, PPR stick lighter materials, PC, UPVC pipe weight of only 60% and 70% of the ABS pipe
    Third, the unique non-toxic: PPR bars is non-toxic products, that is recognized by the authority of the state appraisal department and become the best application of medical, pharmaceutical, environmental protection, water treatment, food processing and manufacturing products.
    Unique autoclavable: PPR rod temperature performance excellence and +110 degrees (atmospheric pressure) can be used for a long pipe no distortion, no cracking, no leakage.
    PPR mechanical strength: PPR rod has a strong resistance to water pressure, air pressure resistance, impact resistance, all indicators are better than other pipes
    PPR bar machining: PPR bars have good machinability, such as cars, milling, planing, drilling, and processing is simple, easy to operate.
    The seven electrical insulation: PPR rod has good electrical insulation, and can be widely used in the preparation of the field of telecommunications, electricity.
    Good sealing performance: PPR bars can be hot-melt as well as welding and screwed connections with good sealing performance.
    Welding performance and fittings: connect using hot melt and welding operation easy
