| HTB52是一种高结晶聚丙烯，具有优异的机械性能，包括弯曲模量、表面硬度和拉伸强度。它们的使用也会降低产品重量。 Description Made from high crystalline PP, compound PP TI51H, HTB52, HTB72 and HTH52 provide superior mechanical properties, including flexural modulus, surface hardness and tensile strength. Their use will also result in reduced product weight. Lightening of materials: Superior mechanical properties - Development of thin wall product - product weight reduction - Talc 30% grade substitution -reduced specific gravity Primary Applications: Heater cases, body consoles and center pillar-UPR. Due to their high scratch-resistance , they are ideal for use in for auto interior parts. In addition, owing to superior heat-resistant characteristics, these products can effectively be used in high-temperature conditions such as in engines and in air-conditioning system parts. Characteristics Outstanding mechanical properties including flexural modulus and surface hardness Remarkable plasticity due to low-shear stress and shear-viscosity at high shear rates, such as in injection molding Reduced cooling time and improved productivity due to the high crystallization speed unique to high crystalline PP Advantages over existing PP compounds due to significantly higher scratch- and heat resistance. Applications Interior parts for automobiles, body-consoles, pillars, trim and heater cases: Heat-resistance and weatherability. Prevents deformation and discoloration of car parts caused by heat within closed spaces and ultraviolet rays during summer. Anti-static characteristics, Prevent static-electricity, which can affect electronic systems in automobiles. Superior processability and scratch-resistance: Superior processability allows better finishes, while use of high crystalline PP affords excellent scratch and heat resistance; ideal for interior parts and air conditioner components. |

药物融入聚合物中 英国开发世界首款布洛芬高分子胶布
2015-12-31 英国华威大学(The University of Warwick)的研究人员和Medherant公司近日研究出一款新胶布，可将大量药物(超过胶布30%重量)融合到胶布的聚合物基体中。药物通过胶布，以平稳速度，逐渐渗透到患者皮肤中，渗透时间可超过12个小时。 据研究人员介绍，这款胶布将助力一系列新型且长效、缓解疼痛的非处方药品。这些药品能够用于治疗常见的慢性背痛和神经痛，无需口服存在潜在破坏性剂量的药品。 “目前市面上仅有少数现有聚合物适用于这种透皮胶布――能 |
