产品详细信息
纺粘非织造布用优质PP颗粒
PP颗粒,化学名称:聚丙烯,特点:密度低,强度刚度、硬度和耐热性优于低压聚乙烯,可在100度左右使用。绝缘性好,在低温下不易磨损,但在高温下不易损坏。适用于制造一般机械零件、耐腐蚀零件和绝缘零件
1。PP颗粒特征:PP颗粒是一种半结晶材料。它比聚乙烯更硬,熔点更高。由于均聚物类型的PP在温度低于0°C时非常脆弱,因此许多商用PP材料是添加1至4%乙烯的无规共聚物或乙烯含量比更高的钳形共聚物。共聚物PP材料具有较低的热变形温度(100°C)、较低的透明度、较低的光泽度和较低的刚性,但具有更强的冲击强度随着乙烯含量的增加,PP颗粒的强度增加。PP的维卡软化温度为150°C。由于高结晶度,该材料具有良好的表面刚度和耐刮擦性。PP不存在环境应力开裂的问题。一般来说,PP是通过添加玻璃纤维、金属添加剂或热塑性橡胶来改性的
聚丙烯颗粒的流速MPP在1到40之间。MFR较低的PP材料具有更好的抗冲击性,但延展性较低。对于相同的MFR材料,共聚物类型的强度高于均聚物类型的强度。由于结晶,PP的收缩率相当高,一般为1.8%至2.5%。收缩方向均匀性比PE-HD等材料好得多。加入30%的玻璃添加剂可以将收缩率降低到0.7%均聚物和共聚物PP颗粒均具有优异的吸湿性、耐酸碱腐蚀性和溶解性。然而,它不耐芳烃(如苯)溶剂、氯化烃(四氯化碳)溶剂等。PP也不像PE那样耐高温氧化

Product Details
High Quality PP Granule For Spunbonded Nonwoven
PP Granule, chemical name: polypropylene, characteristics: low density, strength stiffness, hardness and heat resistance are better than low pressure polyethylene, can be used at about 100 degrees. Has good electrical properties and high-frequency insulation is not affected by humidity, but becomes brittle at low temperatures, not wear-resistant, and easy to age. Suitable for making general mechanical parts, corrosion-resistant parts and insulating parts.
1. PP GranuleFeatures:
PP Granule
is a semi-crystalline material. It is harder than PE and has a higher melting point. Since the PP temperature of the homopolymer type is very fragile when the temperature is below 0 ° C, many commercial PP materials are random copolymers added with 1 to 4% ethylene or clamp copolymers with a higher ratio of ethylene content. Copolymer PP materials have a lower heat distortion temperature (100 ° C), lower transparency, lower gloss, and lower rigidity, but have stronger impact strength.
The strength of PP Granule increases with increasing ethylene content. The Vicat softening temperature of PP is 150 ° C. Due to the high crystallinity, this material has good surface stiffness and scratch resistance. PP does not have the problem of environmental stress cracking. Generally, PP is modified by adding glass fiber, metal additives or thermoplastic rubber.
The flow rate MPP of PP Granule ranges from 1 to 40. PP materials with low MFR have better impact resistance but lower ductility. For the same MFR material, the strength of the copolymer type is higher than that of the homopolymer type. Due to crystallization, the shrinkage of PP is quite high, generally 1.8 to 2.5%. And the direction uniformity of shrinkage is much better than PE-HD and other materials. Adding 30% glass additives can reduce the shrinkage to 0.7%.
Both homopolymer and copolymer PP Granule have excellent moisture absorption resistance, acid and alkali corrosion resistance, and solubility resistance. However, it is not resistant to aromatic hydrocarbon (such as benzene) solvents, chlorinated hydrocarbon (carbon tetrachloride) solvents, etc. PP is also not as resistant to oxidation at high temperatures as PE.
