| 聚丙烯PPH 12020是一种澄清的高流动性均聚物，其熔体流动指数为60 g/10 min。聚丙烯PPH 12020的设计具有很高的刚度和出色的透明度。适用于透明包装的注塑成型。 Unreinforced grades have abundant strength and flexibility, and have strong characteristics against brittleness. UL-certified slow-burning(94HB) and self-extinguishing grades(94V-0,V-2) exist, and electrical properties exhibited are the highest of any thermoplastic. Low water absorption is exhibited, and excellent electrical properties(CTI and GWIT) are retained over extended periods of usages, even with widely varied temperature and humidity conditions. The surface of molded products is smooth, and a low coefficient of friction is exhibited.As the amount of froction is low, PBT is suitable for use in application requiring friction and wear properties. The material is exceptionally reliable, with small in-use dimensional variation, and superior molding stability and dimensional precision. Long-term chemical resistance is exceptional, and at room temperature, there is almost no degradation in properties after. Both unreinforced and reinforced grades exhibit exceptional flowability, and excellent processability. Application:VCD drive frames Connectors Trimmers Switch buttons for gas-fired instantaneous water heaters Relay blocks Driers Rectifiers Outer handles Height sensor cases Door mirror stays Drive component housings Energy saving lamp. |

春风无常 农膜有何影响
2018-04-23 4月5日长江以北地区有4-6级偏北风，阵风7-8级，西北地区、华北、黄淮等地的部分地区有浮尘或扬沙。4月5日至4月10日数日，大风黄色预警不断。此次大风的力度我们有目共睹，再到大棚种植基地去逛一逛，那就真的让人伤心了。 据当时大棚种植基地现场拍摄的视频观看，大棚膜在狂风中飞舞，不少大棚膜被掀开，尤其是大棚两侧的围栏用膜，很容易吹开。农户刚铺好的姜膜，主要是土壤覆盖，有些也被吹的到处漏风或已掀开。 春天虽然气候逐渐转暖，但是大风无常，倒春寒还是时有发生。据了解 |
